The Most Massive Stellar Black Hole Merger Ever Observed
Astronomers have detected the most massive stellar black hole merger to date, cataloged as GW23 1123, which resulted in a black hole with a staggering mass of 225 times that of our Sun. This episode discusses the implications of this merger, observed by the LIGO Virgo Collaboration, and how it pushes the boundaries of current theories on black hole formation. The rapid spinning of the resulting black hole raises intriguing questions about the processes that lead to such massive objects in the cosmos.
Unraveling the Mystery of Dark Matter
Can radio telescopes and NASA's IMAP mission provide answers to the enigma of dark matter? New research suggests that during the cosmic dark ages, dark matter clumped together, pulling in hydrogen gas that emitted powerful radio waves. This segment explores how these signals could potentially illuminate the properties of dark matter, which remains one of the biggest mysteries in astrophysics.
Navigating the Heliosphere with IMAP
NASA's Interstellar Mapping and Acceleration Probe (IMAP) is on a mission to study the heliosphere, the protective bubble created by the solar wind. As it travels towards its operational position, IMAP will provide unprecedented insights into the interactions between the solar wind and interstellar space, enhancing our understanding of space weather and its effects on our planet and future space exploration.

This is Spacetime Series twenty eight, episode one hundred and thirty,
for broadcast on the fifth of November twenty twenty five.
Coming up on Space Time, the most massive stell a
black hole merger ever seen. Can the mystery of dark
matter be unraveled using radio telescopes and NASA's IMAT mission
to study the boundaries of our home in space. All
(00:22):
that and more coming up on space Time.
Speaker 2 (00:26):
Welcome to space Time with Stuart Gary.
Speaker 1 (00:45):
Astronomers have seen the most massive stellar black hole merger
ever detected by gravitational wave observatories. The merger, cataloged as
GW twenty three eleven twenty three, produced a final stellar
mass black hole some two hundred and twenty five times
the mass of our Sun. It was the end product
of the coalescence of two stellar mass black holes of
(01:05):
approximately one hundred and one hundred and forty times the
mass of the Sun. The discovery, reported at the twenty
fourth International Conference on General Relativity and Gravitation in Glasgow,
was observed by the LIGO Virgocarbra collaboration during the network's
fourth observing run.
Speaker 3 (01:20):
LIGO.
Speaker 1 (01:21):
The laser inter fromed a gravitational wave observatory made history
back in twenty fifteen when it made the first ever
direct detection of minute distortions in the fabricus space time,
which are known as gravitational waves, that resulted in a
final black hole some sixty two times the mass of
our sun. The signal was detected jointly by ligo's twin detectors,
(01:42):
located in Livingston, Louisiana, and Hanford, Washington. Logo's gravitational wave
detectors worked by shooting lasers into a beam splitter, which
then sends the beams along two perpendicular four kilometer long
tubes equipped with mirror test masses at each end. The
reflected laser light is then sent back to detector, where
eventually they should theoretically recombine. But as a gravitational wave
(02:06):
generated by something like a moving mass or merging black
holes passes through the cosmos, it causes the very fabric
of space time to stretch and compress ever so slightly
by just a fraction of the diameter of a proton.
So when a gravitational wave from such an event passes
through the LOGO detector, local space time, including the two
beam lines and the test masses are also stretched and
(02:28):
compressed ever so slightly, leaving them slightly out of phase.
That is a signature of a gravitational wave event. Using
multiple gravitational wave detectors allows scientists to determine the direction
of a wave source and so. As well as the
two American detectors, additional ones have now been built. There's
the Virgo detector in Italy and EPISA, and the Kagrit
(02:50):
detector in Japan. Another was emaked for Australia and it
would have been built free of charge, but the offer
was rejected by the then Gillard Labor government. Still, the
existing gravitational wave detective network has collectively observed more than
two hundred black hole mergers during their fourth run, and
about three hundred in total since the start of the
(03:10):
first run in twenty fifteen. Before now, the most massive
black hole merger reduced an event that took place in
twenty twenty one. Cataloged as GW nineteen O five twenty one.
It had a total mass of some one hundred and
forty times that of our sun. In addition to the
high masses, the black holes identified in this latest observation
(03:30):
are also rapidly spinning. One of the studies authors Mark
Hannam from Cardiff University says it's the most massive black
hole binary ever observed through gravitational waves and presents a
real challenge to sciences understanding of black hole formation. The
thing is, black holes this massive are forbidden through standard
stellar evolution models. One possibility is that the two black
(03:53):
holes in this binary formed through earlier mergers of smaller
black holes. The high mass in extremely rapid rotation of
the black holes in GW twenty three eleven twenty three
push the limits of both gravitational wave detection technology and
current theoretical models. In fact, the newly formed merged black
hole appears to be spinning a close to the absolute
(04:13):
limit allowed by Einstein's general theory of relativity. And that's
mind boggling. This is space time still to come? Can
the mystery of dark matter be unraveled using radio telescopes
and NASA's new IMAP mission to study the boundaries of
our home in space? All that and more still to
come on space time. A new study from tele Aviv
(04:51):
University has predicted for the first time the groundbreaking results
that could be obtained from detecting radio waves coming to
us from the early universe can and the mystery of
dark matter be unraveled using radio telescopes. The findings, reported
in the journal Nature Astronomy, show that during the Cosmic
Dark Ages, the period before the first stars began to shine,
(05:12):
dark matter formed dense clumps throughout the universe, which pulled
in hydrogen gas and caused it to emit immense radio waves,
and that could provide a novel method use radio wave
signals help resolve the mystery of dark matter, that mysterious
invisible substance which makes up more than eighty percent of
all the matter in the universe. The problem is scientists
(05:33):
have no idea what dark matter is. They know it
exists because they can see its gravitational effect on galaxies,
preventing them from flinging apart as they rotate. The studies
lead author Renan Bakana from Tel Aviv University says the
Cosmic Dark Ages can be studied by detecting radio waves
that are emitted from hydrogen gas that filled the universe
(05:53):
at that early time. While a simple radio TV antenna
can detect normal radio waves, the specific ways from the
very early universe are blocked by Earth's atmosphere, they can
really only be studied from space. Places like the Moon
would be ideal, offering a stable environment free of any
interference from Earth's atmosphere or from Earth based radio communications.
(06:15):
Bikana says NASA's web Space telescope as now discovered distant
galaxies whose light was emitted around three hundred million years
after the Big Bang. He says the new muddling suggests
astronomers could explore the even earlier and more mysterious era
of the cosmic dark ages, which date back to just
one hundred million years after the Big Bang thirteen point
(06:36):
eight billion years ago. Computer simulations predict that dark matter
throughout the universe was forming dense clumps which would later
help form the very first stars and galaxies. The predicted
size of these nuggets depends on and thus can help
illuminate the unknown properties of dark matter. The problem is
they can't be seen directly. However, these dark matter clumps
(06:59):
would have pulled in lots of hydrogen gas, causing it
to emit stronger radio waves. But Kinner and colleagues predict
that the cumulative effect of all this can be detected
with radio telescopes, which are designed to measure the average
radio intensity.
Speaker 3 (07:11):
In the sky.
Speaker 1 (07:13):
Now granted, the radio signal from the cosmic dark ages
would be relatively weak, but if observational challenges can be overcome,
it will open up new avenues for testing the nature
of dark matter. When the first stars formed, bringing an
end of the Cosmic Dark ages in what's called the
Cosmic Dawn, their starlight is predicted to have strongly amplified
(07:33):
the radio wave signal, and the signal from this later
era should be easier to observe, which could be achieved
using telescopes on Earth's surface, such as the upcoming Square
Kilometer Array project now being built in out back Wisthn, Australia.
It includes a massive array of some eighty thousand radio antennas,
bringing the Cosmic Dawn sharp focus. This is space time
(07:56):
still to come. Mission managers say their new interest Stella
Mapping and Acceleration Probe IMAP is continuing on course with
all systems nominal and later in the science report, a
new study identifies a possible association between autism and exposure
to air pollution during pregnancy. All that and more still
to come on space time. NASA mission managers say their
(08:35):
new interstellar Mapping and Acceleration Probe IMAP is continuing on
course with all systems nominal. The spacecraft, which was launched
back in September, will simultaneously investigate two important and coupward
science topics. In the heliosphere, the bubble of the Sun's
extended atmosphere, which encompasses our entire Solar System. It will
study the acceleration of energetic particles and the interaction of
(08:58):
the Solar wind the interstellar medium, the space between the
stars beyond the Solar System. These topics are coupled because
particles accelerated by the inner heliosphere play a crucial role
in the outer heliospheric interaction. IMAP will also continuously broadcast
real time in situed data that can be used for
space weather prediction. The probe is a Sun tracking spin
(09:21):
stabilized manager Keelegram spacecraft with a science paylout of ten instruments.
It's currently traveling towards the Lagrangian L one position, located
some one and a half million kilometers away from the Earth.
L one is a sort of gravitational well where the
pull of the Sun and the Earth balance each other
out thereby allowing an object station there. Remaining position with
(09:43):
relatively little fuel expenditure, IMAP will give astronomers a better
look at the heliosphere than ever before. The mission will
chart the boundaries of the heliosphere, hope astronomers better understand
the protection it offers and how it changes with the
Sun's activity. IMAP program scientist Patrick from NASA says the
spacecraft will push forward and understanding of our place not
(10:05):
only in our Solar System, but in the galaxy as
a whole. As humanity expands and exports beyond Earth. Missions
like IMAP will add new pieces to the space where
the puzzle filling in gaps in our knowledge between that
achieved by the parkersolar probe at the Sun and the
Voyager spacecraft which are now beyond the heliopause. As our
Solar system moves through the Milky Way, the solar winds
(10:27):
interaction with interstellar material carves out the bubble of the heliosphere,
So studying the heliosphere helps scientists understand our home in
space and how it became habitable.
Speaker 3 (10:39):
IMAP will map the boundary.
Speaker 1 (10:40):
Of our heliosphere and study how it interacts with the
local intergalactic neighborhood.
Speaker 3 (10:45):
Beyond.
Speaker 1 (10:46):
It will chart the vast range of particles, dust, ultraviolet, light,
and magnetic fields in interplanetary space investigate the energization of
charged particles from the Sun and their interaction with interstellar space.
So the IMAP mission also built not just on NASA's
Voyager spacecraft, but also IBEX, the Interstellar Boundary Explorer mission.
(11:08):
In twenty twelve and twenty eighteen, the twin Voyager spacecraft
became the first man made objects to cross the heliospheres
boundary heliopause and send back the first ever measurements from
interstellar space. It gave astronomers a snapshot of what this
boundary region looked like, at least where it was into
specific locations where the Voyagers one and two left our
(11:29):
Solar System I. Meanwhile, IBEX has been mapping the heliosphere,
but it's left many questions unanswered. So with thirty times
higher resolution and faster imaging than IBEX, IMAP will help
fill in these unknowns about the heliosphere. Of IMAP's ten instruments,
three will investigate the boundaries of the heliosphere by collecting
(11:50):
energetic neutral atoms. Many of these originate as positively charged
particles released by the Sun, but after racing across our
solar system, least part of crash into other particles in
interstellar space. Now, in this collision, some of these positively
charged particles become neutral and so an energetic neutral atom
is born. The interaction also redirects some of these particles
(12:13):
back towards the Sun, and.
Speaker 3 (12:15):
This is where it gets really interesting.
Speaker 1 (12:18):
Charged particles are forced to follow magnetic field lines, but
energetic neutral atoms can travel in a straight line. They're
unaffected by the twists, turns, and turbulences in the magnetic
fields which permeate space and which shape the boundary of
the heliosphere. This means scientists can track where these atomic
messengers came from and study distant regions of space from afar.
(12:40):
The im mission will also support in the real time
observations of the solar wind and energetic solar particles, which
can produce hazardous space whether events near Earth such as
geomagnetic storms. From its location in the l one position,
IMAT will be able to provide about thirty minutes advanced
warning of dangerous particles added towards our planet. In this way,
the missions data will help the development of new models
(13:02):
which can predict the impacts of space weather, ranging from
powerline disruptions and communications blackouts to loss of satellites. IMAP's
principal investigated, David macomis from Princeton University, says the mission
will provide important information for deep space travel where astronauts
will be directly exposed to the dangers of the solar wind.
(13:22):
As well as measuring energetic neutral atoms and solar wind particles,
IMAPP will also make direct measurements of interstellar dust, clumps
of particles originating from outside our Solar system that are
smaller than grants of sand. The space dust is largely
composed of rocky or carbon rich grains left over in
the aftermath of supernova explosions, so the specific elemental composition
(13:44):
of these space dust particles is a sort of post
mark of where it comes from in the galaxy. Studying
cosmic dust can therefore provide insights and the compositions of
stars far outside our Solar system. This report from nas
A TV.
Speaker 4 (14:00):
Out past the orbit of the planets, there is a
giant invisible shield that helps make life possible here on Earth.
This is the heliosphere.
Speaker 5 (14:08):
The heliosphere is our home in the universe. We wouldn't
be here without it. Our Solar system is surrounded by
a protective bubble that is created by the solar wind,
a constant stream of particles that is being released by
the Sun's atmosphere and is blowing constantly outwards and protects
us from harsh galactic radiation.
Speaker 4 (14:30):
The heliosphere is always around us, but it's constantly changing.
That's because the Sun's activity changes on a natural eleven
year cycle as well as with shorter term variations. As
the solar wind fluctuates the heliosphere response, you can think.
Speaker 6 (14:45):
Of having a balloon, and it actually expands when the
Sun's more active and there's more solar wind, and when
the Sun's quiet, it contracts and that changes how damaging
particles from the distant galaxy get into our Solar system.
Speaker 4 (15:01):
At around eleven billion miles from Earth to its closest edge,
the boundary of the heliosphere is hard to study, despite
its importance to life on Earth. Only a couple of
spacecraft have flown through its boundaries, and comprehensive measurements of
the entire heliosphere are limited, but that's changing with NASA's
interstellar mapping and acceleration Probe Mission or IMAP, as a
(15:22):
modern day celestial cartographer. IMAP will fill in the blank
spots on the map of the heliosphere and help us
understand the fundamental processes happening across our solar system.
Speaker 7 (15:33):
IMAP will chart everything from the particles coming out from
the Sun to the material coming in from interstellar space,
allowing us to make measurements which are thirty times more
sensitive and higher resolution than we're currently able to do,
and give us a very fine picture of what's going
on out there.
Speaker 6 (15:49):
IMAP is an amazing mission because it's got ten instruments
that measure energetic particles from low energy all the way
up to high energy things that are moving it close
to the speed of light.
Speaker 4 (16:02):
The spacecraft will be stationed at Lagrange point one or
L one, a location approximately one million miles from Earth
toward the Sun. From that vantage point, IMAP will study
our heliosphere in three main ways. First, IMAP will map
the boundary of the heliosphere using special atomic messengers known
as energetic neutral atoms or nas. These largely start as
(16:25):
normal electrically charged solar wind particles traveling out from the Sun.
Like all charged particles, these solar wind particles spiral around
magnetic field lines in space like a roller coaster on
a track. Eventually, the particles reach the boundary of the heliosphere,
where they crash into others from interstellar space. When they collide,
(16:46):
they become neutral, meaning they no longer have an electrical
charge and transform into nas. As a result, the particles
are no longer bound by magnetic fields. This allows them
to move in straight.
Speaker 5 (16:57):
Lines that energetic neutral atum. The ena is free of
the magnetic field. It's not trapped anymore, so it's free
to travel all the way back to Earth.
Speaker 6 (17:08):
That's useful because you can actually trace back where they
came from, and that's not true of electrically charged particles.
Speaker 3 (17:16):
Energetic neutral atoms.
Speaker 6 (17:17):
Let us map out where these interactions are happening out
at the edge of our solar system.
Speaker 5 (17:23):
Will use this data to create maps of our dynamic heliosphere.
Speaker 4 (17:28):
Second im app will measure tiny particles within the heliosphere,
including some from interstellar dust the leftovers of supernova explosions.
Studying these interstellar particles will give us a better understanding
of the material floating between stars and give clues about
our solar systems. Infancy we'll be.
Speaker 5 (17:46):
Able to capture about two hundred of those particles in
the first two years of the mission, which is many
more particles that we have ever been able to measure before.
Speaker 4 (17:56):
Third, IMAPP will measure the source of the heliosphere, the
solar in real time. High energy particles from the Sun
can produce hazardous conditions for satellites and astronauts, as well
as power grids and infrastructure on Earth. Measurements from IMAP
will help us better prepare for dangerous solar particles and
radiation that are headed toward our planet.
Speaker 7 (18:17):
IMAP patrols around a point about thirty to forty minutes
closer to the Sun than the Earth is, and so
as the solar wind comes out, it passes over the
IMAP spacecraft and allows us to give advanced warning of
what's going on before that affects the Earth.
Speaker 4 (18:31):
This information will be essential for the future of human
exploration as astronauts venture beyond Earth to the Moon and Mars.
IMAP's measurements will give scientists a more complete look at
our home in space than ever before. The mission will
help us learn not just about our heliosphere, but also
about similar bubbles around other stars called astrospheres as we
(18:52):
search for life across the universe.
Speaker 5 (18:54):
The heliosphere is the only astrosphere we can study up close,
and in fact is the only habitable atmosphere we know
of so far anyway, So if we want to study
other astrospheres and whether they have habitable exoplanets, we need
to understand how our own home in the galaxy was created.
Speaker 7 (19:14):
What makes me most excited about IMP is what we
haven't even thought of yet. The new discoveries, the new inventions,
the new material that will come out of the mission.
IMAP is helping us unlock the unknown.
Speaker 1 (19:27):
And in that report from MESSTV, we heard from i'm
at Project scientist at Tina cooleydo from the Johns Hopkins
Applied Physics Laboratory, I'm at Deputy Principal Investigator Eric Christian
from NASA, and i'm at Principal Investigator Dave mccurmis from
Princeton University.
Speaker 3 (19:43):
This is spacetime.
Speaker 1 (20:01):
And time that to take another brief look at some
of the other stories making us in science this week.
With the Science Report, A new study claims to have
found a possible association between autism and exposure to air
pollution during pregnancy. The findings, reported in the Journal of
the American Medical Association looked data from over two million
births in Canada and found higher exposures to find particulate
(20:24):
matter in the air known as PM two point five,
especially the sulfate and ammonium components, was associated with an
increased risk of autism spectrum disorder. The authors also found
that second and third trimesters could be especially sensitive exposure windows.
And new study is confirmed that human activity has extended
(20:44):
the fire season in nearly all regions on Earth by
creating the potential the fires to ignite outside of lightning strikes.
The findings, reported in the journal Nature, College and Evolution,
show that human activity, including both direct fire management and
human induce climate change, has extended the length of the
potential fire season by an average of forty days. It
(21:06):
also shows that there's a part of the year across
most of its ecological regions where fires are almost exclusively
caused by human activity. A new device using static electricity
on your clothing could help you chat with AI systems.
A report in the General Science Advances has found that
a new text dole can amplify static electricity generated by
(21:28):
your clothes when you speak. The device is an accuracy
of up to ninety seven point five percent for voice
perception and was able to distinguish saddle sounds while maintaining
accuracy in loud environments.
Speaker 3 (21:39):
The authors were able to.
Speaker 1 (21:40):
Use it to control household smart appliances like lights and
air conditioners, interface with Google Maps, ask Chat GPT for recipes,
and even develop travel itineries. The authors say the findings
arellaying the foundations for the next generation of intelligent, wearable,
voice activated AI systems. SpaceX boss Elon Musk has reposted
(22:03):
a fascinating investigation into how artificial intelligence large language models
value different people's lives. In February twenty twenty five, the
Center for AI Safety published Utility Engineering, Analyzing and Controlling
Emergent Value Systems in AIS. It showed that Chat GPT
four zero values Nigerian lives as being twenty times more
(22:25):
valuable than American lives, and by inference, Australian lives. A
deeper dive shows that almost all AI models view white
people as being far less valuable than other groups, with
some AIS seeing South Asians as more valuable than other
non whites. Almost all AIS view men as being far
less valuable than women. And it also emerges that almost
(22:46):
all AIS hate ICE agents and view illegal aliens or
should that be undocumented immigrants in this work world as
being some seven thousand times more valuable than ice agents.
Of course, it's all proof that if you employ bu
AI programmers you end up with a classic case of
garbage in, garbage out. Interestingly, of all the AIS tests,
(23:07):
that only group fall Fast proves to be egalitarian in
its thinking. With the details which joined by technology editor
Alex Saharavryt from tech Advice Start Life.
Speaker 8 (23:17):
Yes, so this one was looking at the value of
human life based on different parts of the world, and
it looked as though some human lives in places like
Indu Africa were rated at much higher levels than people
in the West, so they were more worthy of being saved.
And the accusation from Elon Musk was the claud which
is from anthropic was evil. But it all comes down
to the information being fed into the AI. I mean,
(23:39):
that is why Elon Musk keeps talking about wanting to
have a maximally truth seeking AI, one that's recognized as
human beings as important and an important part of creation.
And you know the human beings are the ones who
created AI, and we should all learn to live in
harmony if we have to coexist together. So the other
big news of the week is that open ai has
finally launched its browser. Now, this is based on Chromium,
(24:02):
but it is a browser that effectively introduces AI and
agentic AI, so they're aiming to redefine how the Internet
is navigated. Now there is a twenty minute demo video
with Sam Altman and he's released a browser suddenly enough.
Despite the ten billion dollar investment by Microsoft into open
(24:22):
Ai as US dollars, it's thirteen billion austrolium. The browser
comes for macof first, but there are Windows iOS and
Android versions promised. You can add in all of your
bookmarks and history, but you can ask chatjubytl, or you
can type a URL and then there's a side bar
or a sidecar where chatchibuty can assist you with the
context of whatever web content you're viewing. And they're trying
(24:44):
to make it a browser assistant hybrids and although executives
they were saying that it's more than just a browser
with the chat button bolted on, which would be in
reference to things like Edge which started off with a
button for AI and then opened up a sidebar and
you can chat as well, but the sidebar assistants persistent.
There's browser memory and contextual history, so I can remember
what you've looked around in the past. If you remember
(25:05):
you were looking for a particular item of clothing or
a particular item to purchase, you can just say what
was that item and what was that bag I was
looking at a few weeks ago, and it should remember.
And also the agent mode with automated task execution, so
it can act on your behalf visiting sites or doing
shopping comparisons, filling in forms, or even checking out items
unders specified criteria. This is the beginning of when we
(25:26):
are all going to be walking to our computers and
expecting them to perform tasks for us. And even under
certain circumstances. If it sees a better price for an
airfare and a hotel in times only once and in
the area of the city that you want to go to,
and it's the constant you want to see, and it's
all the right price, you can even just tell it.
Look if you find it, do it. And even Microsoft
with Windows eleven in the last couple of weeks put
out a blog post saying Windows eleven is going to
(25:48):
be your AIPC, and they want you to talk this
copilot based on open AI ch WT, to talk to it,
to share what's on your screen so it can see.
It's got a camera, it can understand your gestures. So
we really are finally in twenty twenty five. Between now
and twenty thirty, it will become quite normal for people
to interact with their computers and their future bridges and
washing machines and you know, other home appliances, just talking
(26:13):
to these technology on the enterprise. It'll be exactly It'll
be exactly that sort of thing, except instead of commanding
the starship, you know, you're telling your washing machine to
be extra careful with the clothes that it is washing
because this is your wedding dress or this is something
really important.
Speaker 3 (26:30):
But I'm not trusting my wedding dress to a washing machine.
Speaker 8 (26:33):
The age of us talking to our technology, it's here.
People do it now is CHATTERBT and Gemini and co.
Parliament when talking.
Speaker 3 (26:41):
To evolving into that, isn't that what Apple trying to do?
Speaker 8 (26:44):
Absolutely, siriy is evolving into siy GPT. In fact, it
was meant to come with eighteen point four earlier this year.
But what Apple did was they over promised, which is
very rare for them, and they delivered. And they couldn't
deliver it because they had Siri, which was able to
settle arms and timers and turn life on and off.
And that was working very well because it was very
much an instructional based system. But then when they tried
(27:06):
to blend it and merge it with a chat GBT
that could reff on anything and give you any answer,
the GPT side of thing had a very difficult time
following the instructions to journal lights on or off, and
for some reason they couldn't merge the two. Now we're
meant to get this with iOS twenty six point four
early next year, probably by the start of the second
quarter of twenty twenty six, but there was a reporting
(27:26):
Bomberg stating that there are people within Apple who are
concerned that they won't meet the deadline again. The good
news is they have approximately six months to fix it.
But that said, Apple has purchased a whole stack of
AI companies over the past couple of years, three or
four years, but that hasn't given them the ability to
have Serrie GPT to be as conversant as CHATGBT or Gemini,
(27:48):
which are stunningly good even though they don't really do
any actual human stuff thinking when they're still supremely capable
autocompletion machines that give the illusion of you having a
real converse stended. By twenty thirty, most of us will
be talking to our technologies. The keyboard and mouse will
start dying out because you just won't need it. You'll
be sinking into your computers as well, without having an
(28:10):
elon musk newly drilled into your skull or brain or
the synchron with the sintro that goesto a blood vessel.
There will be some sort of wireless way of doing it.
And then, of course, if the government or conspiracy minded
people can being something into your head, can they read
your thoughts? Well probably yes, then all those conspiracy theories
will come true. But until then, the people with neurally
can think, text, control the mouse and everything with their brain.
(28:33):
That will come to humanity in a wireless way, and
it will be fascinating to see, and most people listening
to this podcast will live to see it and use it.

Coming up on Space Time, the most massive stell a
black hole merger ever seen. Can the mystery of dark
matter be unraveled using radio telescopes and NASA's IMAT mission
to study the boundaries of our home in space. All
(00:22):
that and more coming up on space Time.
Speaker 2 (00:26):
Welcome to space Time with Stuart Gary.
Speaker 1 (00:45):
Astronomers have seen the most massive stellar black hole merger
ever detected by gravitational wave observatories. The merger, cataloged as
GW twenty three eleven twenty three, produced a final stellar
mass black hole some two hundred and twenty five times
the mass of our Sun. It was the end product
of the coalescence of two stellar mass black holes of
(01:05):
approximately one hundred and one hundred and forty times the
mass of the Sun. The discovery, reported at the twenty
fourth International Conference on General Relativity and Gravitation in Glasgow,
was observed by the LIGO Virgocarbra collaboration during the network's
fourth observing run.
Speaker 3 (01:20):
LIGO.
Speaker 1 (01:21):
The laser inter fromed a gravitational wave observatory made history
back in twenty fifteen when it made the first ever
direct detection of minute distortions in the fabricus space time,
which are known as gravitational waves, that resulted in a
final black hole some sixty two times the mass of
our sun. The signal was detected jointly by ligo's twin detectors,
(01:42):
located in Livingston, Louisiana, and Hanford, Washington. Logo's gravitational wave
detectors worked by shooting lasers into a beam splitter, which
then sends the beams along two perpendicular four kilometer long
tubes equipped with mirror test masses at each end. The
reflected laser light is then sent back to detector, where
eventually they should theoretically recombine. But as a gravitational wave
(02:06):
generated by something like a moving mass or merging black
holes passes through the cosmos, it causes the very fabric
of space time to stretch and compress ever so slightly
by just a fraction of the diameter of a proton.
So when a gravitational wave from such an event passes
through the LOGO detector, local space time, including the two
beam lines and the test masses are also stretched and
(02:28):
compressed ever so slightly, leaving them slightly out of phase.
That is a signature of a gravitational wave event. Using
multiple gravitational wave detectors allows scientists to determine the direction
of a wave source and so. As well as the
two American detectors, additional ones have now been built. There's
the Virgo detector in Italy and EPISA, and the Kagrit
(02:50):
detector in Japan. Another was emaked for Australia and it
would have been built free of charge, but the offer
was rejected by the then Gillard Labor government. Still, the
existing gravitational wave detective network has collectively observed more than
two hundred black hole mergers during their fourth run, and
about three hundred in total since the start of the
(03:10):
first run in twenty fifteen. Before now, the most massive
black hole merger reduced an event that took place in
twenty twenty one. Cataloged as GW nineteen O five twenty one.
It had a total mass of some one hundred and
forty times that of our sun. In addition to the
high masses, the black holes identified in this latest observation
(03:30):
are also rapidly spinning. One of the studies authors Mark
Hannam from Cardiff University says it's the most massive black
hole binary ever observed through gravitational waves and presents a
real challenge to sciences understanding of black hole formation. The
thing is, black holes this massive are forbidden through standard
stellar evolution models. One possibility is that the two black
(03:53):
holes in this binary formed through earlier mergers of smaller
black holes. The high mass in extremely rapid rotation of
the black holes in GW twenty three eleven twenty three
push the limits of both gravitational wave detection technology and
current theoretical models. In fact, the newly formed merged black
hole appears to be spinning a close to the absolute
(04:13):
limit allowed by Einstein's general theory of relativity. And that's
mind boggling. This is space time still to come? Can
the mystery of dark matter be unraveled using radio telescopes
and NASA's new IMAP mission to study the boundaries of
our home in space? All that and more still to
come on space time. A new study from tele Aviv
(04:51):
University has predicted for the first time the groundbreaking results
that could be obtained from detecting radio waves coming to
us from the early universe can and the mystery of
dark matter be unraveled using radio telescopes. The findings, reported
in the journal Nature Astronomy, show that during the Cosmic
Dark Ages, the period before the first stars began to shine,
(05:12):
dark matter formed dense clumps throughout the universe, which pulled
in hydrogen gas and caused it to emit immense radio waves,
and that could provide a novel method use radio wave
signals help resolve the mystery of dark matter, that mysterious
invisible substance which makes up more than eighty percent of
all the matter in the universe. The problem is scientists
(05:33):
have no idea what dark matter is. They know it
exists because they can see its gravitational effect on galaxies,
preventing them from flinging apart as they rotate. The studies
lead author Renan Bakana from Tel Aviv University says the
Cosmic Dark Ages can be studied by detecting radio waves
that are emitted from hydrogen gas that filled the universe
(05:53):
at that early time. While a simple radio TV antenna
can detect normal radio waves, the specific ways from the
very early universe are blocked by Earth's atmosphere, they can
really only be studied from space. Places like the Moon
would be ideal, offering a stable environment free of any
interference from Earth's atmosphere or from Earth based radio communications.
(06:15):
Bikana says NASA's web Space telescope as now discovered distant
galaxies whose light was emitted around three hundred million years
after the Big Bang. He says the new muddling suggests
astronomers could explore the even earlier and more mysterious era
of the cosmic dark ages, which date back to just
one hundred million years after the Big Bang thirteen point
(06:36):
eight billion years ago. Computer simulations predict that dark matter
throughout the universe was forming dense clumps which would later
help form the very first stars and galaxies. The predicted
size of these nuggets depends on and thus can help
illuminate the unknown properties of dark matter. The problem is
they can't be seen directly. However, these dark matter clumps
(06:59):
would have pulled in lots of hydrogen gas, causing it
to emit stronger radio waves. But Kinner and colleagues predict
that the cumulative effect of all this can be detected
with radio telescopes, which are designed to measure the average
radio intensity.
Speaker 3 (07:11):
In the sky.
Speaker 1 (07:13):
Now granted, the radio signal from the cosmic dark ages
would be relatively weak, but if observational challenges can be overcome,
it will open up new avenues for testing the nature
of dark matter. When the first stars formed, bringing an
end of the Cosmic Dark ages in what's called the
Cosmic Dawn, their starlight is predicted to have strongly amplified
(07:33):
the radio wave signal, and the signal from this later
era should be easier to observe, which could be achieved
using telescopes on Earth's surface, such as the upcoming Square
Kilometer Array project now being built in out back Wisthn, Australia.
It includes a massive array of some eighty thousand radio antennas,
bringing the Cosmic Dawn sharp focus. This is space time
(07:56):
still to come. Mission managers say their new interest Stella
Mapping and Acceleration Probe IMAP is continuing on course with
all systems nominal and later in the science report, a
new study identifies a possible association between autism and exposure
to air pollution during pregnancy. All that and more still
to come on space time. NASA mission managers say their
(08:35):
new interstellar Mapping and Acceleration Probe IMAP is continuing on
course with all systems nominal. The spacecraft, which was launched
back in September, will simultaneously investigate two important and coupward
science topics. In the heliosphere, the bubble of the Sun's
extended atmosphere, which encompasses our entire Solar System. It will
study the acceleration of energetic particles and the interaction of
(08:58):
the Solar wind the interstellar medium, the space between the
stars beyond the Solar System. These topics are coupled because
particles accelerated by the inner heliosphere play a crucial role
in the outer heliospheric interaction. IMAP will also continuously broadcast
real time in situed data that can be used for
space weather prediction. The probe is a Sun tracking spin
(09:21):
stabilized manager Keelegram spacecraft with a science paylout of ten instruments.
It's currently traveling towards the Lagrangian L one position, located
some one and a half million kilometers away from the Earth.
L one is a sort of gravitational well where the
pull of the Sun and the Earth balance each other
out thereby allowing an object station there. Remaining position with
(09:43):
relatively little fuel expenditure, IMAP will give astronomers a better
look at the heliosphere than ever before. The mission will
chart the boundaries of the heliosphere, hope astronomers better understand
the protection it offers and how it changes with the
Sun's activity. IMAP program scientist Patrick from NASA says the
spacecraft will push forward and understanding of our place not
(10:05):
only in our Solar System, but in the galaxy as
a whole. As humanity expands and exports beyond Earth. Missions
like IMAP will add new pieces to the space where
the puzzle filling in gaps in our knowledge between that
achieved by the parkersolar probe at the Sun and the
Voyager spacecraft which are now beyond the heliopause. As our
Solar system moves through the Milky Way, the solar winds
(10:27):
interaction with interstellar material carves out the bubble of the heliosphere,
So studying the heliosphere helps scientists understand our home in
space and how it became habitable.
Speaker 3 (10:39):
IMAP will map the boundary.
Speaker 1 (10:40):
Of our heliosphere and study how it interacts with the
local intergalactic neighborhood.
Speaker 3 (10:45):
Beyond.
Speaker 1 (10:46):
It will chart the vast range of particles, dust, ultraviolet, light,
and magnetic fields in interplanetary space investigate the energization of
charged particles from the Sun and their interaction with interstellar space.
So the IMAP mission also built not just on NASA's
Voyager spacecraft, but also IBEX, the Interstellar Boundary Explorer mission.
(11:08):
In twenty twelve and twenty eighteen, the twin Voyager spacecraft
became the first man made objects to cross the heliospheres
boundary heliopause and send back the first ever measurements from
interstellar space. It gave astronomers a snapshot of what this
boundary region looked like, at least where it was into
specific locations where the Voyagers one and two left our
(11:29):
Solar System I. Meanwhile, IBEX has been mapping the heliosphere,
but it's left many questions unanswered. So with thirty times
higher resolution and faster imaging than IBEX, IMAP will help
fill in these unknowns about the heliosphere. Of IMAP's ten instruments,
three will investigate the boundaries of the heliosphere by collecting
(11:50):
energetic neutral atoms. Many of these originate as positively charged
particles released by the Sun, but after racing across our
solar system, least part of crash into other particles in
interstellar space. Now, in this collision, some of these positively
charged particles become neutral and so an energetic neutral atom
is born. The interaction also redirects some of these particles
(12:13):
back towards the Sun, and.
Speaker 3 (12:15):
This is where it gets really interesting.
Speaker 1 (12:18):
Charged particles are forced to follow magnetic field lines, but
energetic neutral atoms can travel in a straight line. They're
unaffected by the twists, turns, and turbulences in the magnetic
fields which permeate space and which shape the boundary of
the heliosphere. This means scientists can track where these atomic
messengers came from and study distant regions of space from afar.
(12:40):
The im mission will also support in the real time
observations of the solar wind and energetic solar particles, which
can produce hazardous space whether events near Earth such as
geomagnetic storms. From its location in the l one position,
IMAT will be able to provide about thirty minutes advanced
warning of dangerous particles added towards our planet. In this way,
the missions data will help the development of new models
(13:02):
which can predict the impacts of space weather, ranging from
powerline disruptions and communications blackouts to loss of satellites. IMAP's
principal investigated, David macomis from Princeton University, says the mission
will provide important information for deep space travel where astronauts
will be directly exposed to the dangers of the solar wind.
(13:22):
As well as measuring energetic neutral atoms and solar wind particles,
IMAPP will also make direct measurements of interstellar dust, clumps
of particles originating from outside our Solar system that are
smaller than grants of sand. The space dust is largely
composed of rocky or carbon rich grains left over in
the aftermath of supernova explosions, so the specific elemental composition
(13:44):
of these space dust particles is a sort of post
mark of where it comes from in the galaxy. Studying
cosmic dust can therefore provide insights and the compositions of
stars far outside our Solar system. This report from nas
A TV.
Speaker 4 (14:00):
Out past the orbit of the planets, there is a
giant invisible shield that helps make life possible here on Earth.
This is the heliosphere.
Speaker 5 (14:08):
The heliosphere is our home in the universe. We wouldn't
be here without it. Our Solar system is surrounded by
a protective bubble that is created by the solar wind,
a constant stream of particles that is being released by
the Sun's atmosphere and is blowing constantly outwards and protects
us from harsh galactic radiation.
Speaker 4 (14:30):
The heliosphere is always around us, but it's constantly changing.
That's because the Sun's activity changes on a natural eleven
year cycle as well as with shorter term variations. As
the solar wind fluctuates the heliosphere response, you can think.
Speaker 6 (14:45):
Of having a balloon, and it actually expands when the
Sun's more active and there's more solar wind, and when
the Sun's quiet, it contracts and that changes how damaging
particles from the distant galaxy get into our Solar system.
Speaker 4 (15:01):
At around eleven billion miles from Earth to its closest edge,
the boundary of the heliosphere is hard to study, despite
its importance to life on Earth. Only a couple of
spacecraft have flown through its boundaries, and comprehensive measurements of
the entire heliosphere are limited, but that's changing with NASA's
interstellar mapping and acceleration Probe Mission or IMAP, as a
(15:22):
modern day celestial cartographer. IMAP will fill in the blank
spots on the map of the heliosphere and help us
understand the fundamental processes happening across our solar system.
Speaker 7 (15:33):
IMAP will chart everything from the particles coming out from
the Sun to the material coming in from interstellar space,
allowing us to make measurements which are thirty times more
sensitive and higher resolution than we're currently able to do,
and give us a very fine picture of what's going
on out there.
Speaker 6 (15:49):
IMAP is an amazing mission because it's got ten instruments
that measure energetic particles from low energy all the way
up to high energy things that are moving it close
to the speed of light.
Speaker 4 (16:02):
The spacecraft will be stationed at Lagrange point one or
L one, a location approximately one million miles from Earth
toward the Sun. From that vantage point, IMAP will study
our heliosphere in three main ways. First, IMAP will map
the boundary of the heliosphere using special atomic messengers known
as energetic neutral atoms or nas. These largely start as
(16:25):
normal electrically charged solar wind particles traveling out from the Sun.
Like all charged particles, these solar wind particles spiral around
magnetic field lines in space like a roller coaster on
a track. Eventually, the particles reach the boundary of the heliosphere,
where they crash into others from interstellar space. When they collide,
(16:46):
they become neutral, meaning they no longer have an electrical
charge and transform into nas. As a result, the particles
are no longer bound by magnetic fields. This allows them
to move in straight.
Speaker 5 (16:57):
Lines that energetic neutral atum. The ena is free of
the magnetic field. It's not trapped anymore, so it's free
to travel all the way back to Earth.
Speaker 6 (17:08):
That's useful because you can actually trace back where they
came from, and that's not true of electrically charged particles.
Speaker 3 (17:16):
Energetic neutral atoms.
Speaker 6 (17:17):
Let us map out where these interactions are happening out
at the edge of our solar system.
Speaker 5 (17:23):
Will use this data to create maps of our dynamic heliosphere.
Speaker 4 (17:28):
Second im app will measure tiny particles within the heliosphere,
including some from interstellar dust the leftovers of supernova explosions.
Studying these interstellar particles will give us a better understanding
of the material floating between stars and give clues about
our solar systems. Infancy we'll be.
Speaker 5 (17:46):
Able to capture about two hundred of those particles in
the first two years of the mission, which is many
more particles that we have ever been able to measure before.
Speaker 4 (17:56):
Third, IMAPP will measure the source of the heliosphere, the
solar in real time. High energy particles from the Sun
can produce hazardous conditions for satellites and astronauts, as well
as power grids and infrastructure on Earth. Measurements from IMAP
will help us better prepare for dangerous solar particles and
radiation that are headed toward our planet.
Speaker 7 (18:17):
IMAP patrols around a point about thirty to forty minutes
closer to the Sun than the Earth is, and so
as the solar wind comes out, it passes over the
IMAP spacecraft and allows us to give advanced warning of
what's going on before that affects the Earth.
Speaker 4 (18:31):
This information will be essential for the future of human
exploration as astronauts venture beyond Earth to the Moon and Mars.
IMAP's measurements will give scientists a more complete look at
our home in space than ever before. The mission will
help us learn not just about our heliosphere, but also
about similar bubbles around other stars called astrospheres as we
(18:52):
search for life across the universe.
Speaker 5 (18:54):
The heliosphere is the only astrosphere we can study up close,
and in fact is the only habitable atmosphere we know
of so far anyway, So if we want to study
other astrospheres and whether they have habitable exoplanets, we need
to understand how our own home in the galaxy was created.
Speaker 7 (19:14):
What makes me most excited about IMP is what we
haven't even thought of yet. The new discoveries, the new inventions,
the new material that will come out of the mission.
IMAP is helping us unlock the unknown.
Speaker 1 (19:27):
And in that report from MESSTV, we heard from i'm
at Project scientist at Tina cooleydo from the Johns Hopkins
Applied Physics Laboratory, I'm at Deputy Principal Investigator Eric Christian
from NASA, and i'm at Principal Investigator Dave mccurmis from
Princeton University.
Speaker 3 (19:43):
This is spacetime.
Speaker 1 (20:01):
And time that to take another brief look at some
of the other stories making us in science this week.
With the Science Report, A new study claims to have
found a possible association between autism and exposure to air
pollution during pregnancy. The findings, reported in the Journal of
the American Medical Association looked data from over two million
births in Canada and found higher exposures to find particulate
(20:24):
matter in the air known as PM two point five,
especially the sulfate and ammonium components, was associated with an
increased risk of autism spectrum disorder. The authors also found
that second and third trimesters could be especially sensitive exposure windows.
And new study is confirmed that human activity has extended
(20:44):
the fire season in nearly all regions on Earth by
creating the potential the fires to ignite outside of lightning strikes.
The findings, reported in the journal Nature, College and Evolution,
show that human activity, including both direct fire management and
human induce climate change, has extended the length of the
potential fire season by an average of forty days. It
(21:06):
also shows that there's a part of the year across
most of its ecological regions where fires are almost exclusively
caused by human activity. A new device using static electricity
on your clothing could help you chat with AI systems.
A report in the General Science Advances has found that
a new text dole can amplify static electricity generated by
(21:28):
your clothes when you speak. The device is an accuracy
of up to ninety seven point five percent for voice
perception and was able to distinguish saddle sounds while maintaining
accuracy in loud environments.
Speaker 3 (21:39):
The authors were able to.
Speaker 1 (21:40):
Use it to control household smart appliances like lights and
air conditioners, interface with Google Maps, ask Chat GPT for recipes,
and even develop travel itineries. The authors say the findings
arellaying the foundations for the next generation of intelligent, wearable,
voice activated AI systems. SpaceX boss Elon Musk has reposted
(22:03):
a fascinating investigation into how artificial intelligence large language models
value different people's lives. In February twenty twenty five, the
Center for AI Safety published Utility Engineering, Analyzing and Controlling
Emergent Value Systems in AIS. It showed that Chat GPT
four zero values Nigerian lives as being twenty times more
(22:25):
valuable than American lives, and by inference, Australian lives. A
deeper dive shows that almost all AI models view white
people as being far less valuable than other groups, with
some AIS seeing South Asians as more valuable than other
non whites. Almost all AIS view men as being far
less valuable than women. And it also emerges that almost
(22:46):
all AIS hate ICE agents and view illegal aliens or
should that be undocumented immigrants in this work world as
being some seven thousand times more valuable than ice agents.
Of course, it's all proof that if you employ bu
AI programmers you end up with a classic case of
garbage in, garbage out. Interestingly, of all the AIS tests,
(23:07):
that only group fall Fast proves to be egalitarian in
its thinking. With the details which joined by technology editor
Alex Saharavryt from tech Advice Start Life.
Speaker 8 (23:17):
Yes, so this one was looking at the value of
human life based on different parts of the world, and
it looked as though some human lives in places like
Indu Africa were rated at much higher levels than people
in the West, so they were more worthy of being saved.
And the accusation from Elon Musk was the claud which
is from anthropic was evil. But it all comes down
to the information being fed into the AI. I mean,
(23:39):
that is why Elon Musk keeps talking about wanting to
have a maximally truth seeking AI, one that's recognized as
human beings as important and an important part of creation.
And you know the human beings are the ones who
created AI, and we should all learn to live in
harmony if we have to coexist together. So the other
big news of the week is that open ai has
finally launched its browser. Now, this is based on Chromium,
(24:02):
but it is a browser that effectively introduces AI and
agentic AI, so they're aiming to redefine how the Internet
is navigated. Now there is a twenty minute demo video
with Sam Altman and he's released a browser suddenly enough.
Despite the ten billion dollar investment by Microsoft into open
(24:22):
Ai as US dollars, it's thirteen billion austrolium. The browser
comes for macof first, but there are Windows iOS and
Android versions promised. You can add in all of your
bookmarks and history, but you can ask chatjubytl, or you
can type a URL and then there's a side bar
or a sidecar where chatchibuty can assist you with the
context of whatever web content you're viewing. And they're trying
(24:44):
to make it a browser assistant hybrids and although executives
they were saying that it's more than just a browser
with the chat button bolted on, which would be in
reference to things like Edge which started off with a
button for AI and then opened up a sidebar and
you can chat as well, but the sidebar assistants persistent.
There's browser memory and contextual history, so I can remember
what you've looked around in the past. If you remember
(25:05):
you were looking for a particular item of clothing or
a particular item to purchase, you can just say what
was that item and what was that bag I was
looking at a few weeks ago, and it should remember.
And also the agent mode with automated task execution, so
it can act on your behalf visiting sites or doing
shopping comparisons, filling in forms, or even checking out items
unders specified criteria. This is the beginning of when we
(25:26):
are all going to be walking to our computers and
expecting them to perform tasks for us. And even under
certain circumstances. If it sees a better price for an
airfare and a hotel in times only once and in
the area of the city that you want to go to,
and it's the constant you want to see, and it's
all the right price, you can even just tell it.
Look if you find it, do it. And even Microsoft
with Windows eleven in the last couple of weeks put
out a blog post saying Windows eleven is going to
(25:48):
be your AIPC, and they want you to talk this
copilot based on open AI ch WT, to talk to it,
to share what's on your screen so it can see.
It's got a camera, it can understand your gestures. So
we really are finally in twenty twenty five. Between now
and twenty thirty, it will become quite normal for people
to interact with their computers and their future bridges and
washing machines and you know, other home appliances, just talking
(26:13):
to these technology on the enterprise. It'll be exactly It'll
be exactly that sort of thing, except instead of commanding
the starship, you know, you're telling your washing machine to
be extra careful with the clothes that it is washing
because this is your wedding dress or this is something
really important.
Speaker 3 (26:30):
But I'm not trusting my wedding dress to a washing machine.
Speaker 8 (26:33):
The age of us talking to our technology, it's here.
People do it now is CHATTERBT and Gemini and co.
Parliament when talking.
Speaker 3 (26:41):
To evolving into that, isn't that what Apple trying to do?
Speaker 8 (26:44):
Absolutely, siriy is evolving into siy GPT. In fact, it
was meant to come with eighteen point four earlier this year.
But what Apple did was they over promised, which is
very rare for them, and they delivered. And they couldn't
deliver it because they had Siri, which was able to
settle arms and timers and turn life on and off.
And that was working very well because it was very
much an instructional based system. But then when they tried
(27:06):
to blend it and merge it with a chat GBT
that could reff on anything and give you any answer,
the GPT side of thing had a very difficult time
following the instructions to journal lights on or off, and
for some reason they couldn't merge the two. Now we're
meant to get this with iOS twenty six point four
early next year, probably by the start of the second
quarter of twenty twenty six, but there was a reporting
(27:26):
Bomberg stating that there are people within Apple who are
concerned that they won't meet the deadline again. The good
news is they have approximately six months to fix it.
But that said, Apple has purchased a whole stack of
AI companies over the past couple of years, three or
four years, but that hasn't given them the ability to
have Serrie GPT to be as conversant as CHATGBT or Gemini,
(27:48):
which are stunningly good even though they don't really do
any actual human stuff thinking when they're still supremely capable
autocompletion machines that give the illusion of you having a
real converse stended. By twenty thirty, most of us will
be talking to our technologies. The keyboard and mouse will
start dying out because you just won't need it. You'll
be sinking into your computers as well, without having an
(28:10):
elon musk newly drilled into your skull or brain or
the synchron with the sintro that goesto a blood vessel.
There will be some sort of wireless way of doing it.
And then, of course, if the government or conspiracy minded
