Speaker 1 (00:01):
Did you see all these reports about interstellar Comet three
I at liss, I mean the reports are everywhere. Is
this thing another comet? Is it alien technology? Is it
some new type of classification that scientists and astrophysicists don't
even know what it is? Hello Future, it's me keV.
(00:22):
This is a dispatch from the Digital Frontier. The year
is twenty twenty five. The planet is Earth. My name
is Kevin Surreally. This article in BBC Sky at Night
magazine Interstellar Commet threeiat list is currently making its way
through our solar system, offering an incredible opportunity to observe
(00:42):
an ancient relic from deep space. The problem is three
iat lists is soon set to disappear from view as
its trajectory takes it around the opposite side of the
Sun from Earth's perspective. It then won't be visible from
Earth based telescopes until early decent number twenty twenty five.
That's according to the BBC. My guest today is someone
(01:05):
who has captured the attention not just of the scientific community.
He's captured the attention of NASA, which put out a
statement in response to his commentary, but also ordinary folks
like me who are just trying to figure out what
is this thing? What is this thing? It's the third
interstellar object that humanities technology has been able to capture
in the last decade or so. His name is doctor
(01:25):
Avi Loeb. Avi Lobe is a Harvard astrophysicist who has
spent decades at the frontiers of theoretical physics and astronomy,
and who has never shied away from the bold controversial questions.
He is best known for suggesting and researching interstellar objects
that we don't have a plan for on planet Earth,
(01:47):
including Umuamua and now comment three I atlass He joined
Harvard University in nineteen ninety three and earned tenor in
just three years. He went on to serve as the
chair of the Astronomy Department from twenty eleven to twenty twenty,
and today he directs the Institute for Theory and Computation
at the Harvard Smithsonian Center for Astrophysics. He is also
(02:10):
the founding director of Harvard's Black Hole Initiative. But there's
something else. He's a founder of the Galileo Project. This
is an ambitious research initiative dedicated to systemically searching for
evidence of extraterrestrial technology. Near Earth and in our solar system.
He's also a best selling author. But enough of his introduction,
(02:32):
Doctor Low, thank you so much for joining us. I
want to start things off by just catching folks up
to speed. What is comment three I at list in
very simple terms.
Speaker 2 (02:43):
Thank you so much for having me.
Speaker 3 (02:45):
Well, the fundamental question is whether it's a comet or
something else, And then it was an object discovered on
the first of July twenty twenty five. It has several
anomalous characteristics. I mean, first of or, we know that
it came from outside the Solar system because it's moving
at sixty kilometers per second relative to the Sun. That's
(03:07):
way above the speed necessary to escape from the gravitational
pool of the Sun. So it definitely came from outside
the Solar system. And what was unusual about it is
that it moves along a trajectory that is aligned with
the planets around the Sun to within five degrees. And
the chance of that happening at random is one in
(03:27):
five hundred, which raises the question of whether this trajectory
was fine tuned by some intelligence. The object itself is
of an unknown size, but if we assume that the
brightness that it exhibited early on is just the reflection
of sunlight from a solid surface. It has to be
(03:49):
in the tents of kilopaters range bigger than Manhattan Island,
and that means that it's a mass is somewhere between
ten thousand to a million times bigger than the previous
two interstellar objects that were discovered over the past decade.
Speaker 2 (04:04):
This is a new frontier.
Speaker 3 (04:05):
Only now we have those survey telescopes that allow us
to find objects from outside the Solar System and are
offering a completely new way of searching for extraterreational civilizations.
Because in the past we were waiting for a radio
signal to reach us from another civilization. It's just like
waiting for a phone call. Now we can search for
(04:27):
a tennis ball that may have landed in our backyard,
and that's a very different approach. May well be that
the civilization who sent it is not around anymore, that
they are dead now. This object was also unusual in
several other ways. The best image we have of it
was obtained by the Hubble Space telescope, and it features
(04:48):
a glow ahead of the object towards the Sun, rather
than behind it the way we see for comets. In
the case of comets, there is dust that is scuttering
sunlightness that is a myth or shed This.
Speaker 1 (05:01):
Is important, and I want to come back to the
civilization comment that you made, But this is important because
when you don't have to have an astrophysicist agree to
see that this interstellar object is different. I mean, when
people hear the word comet, they think of the tail
of the comet bursting through the sky and they can
see the light. But what you're saying is that the
(05:23):
light of this interstellar object is in the front.
Speaker 3 (05:27):
Right in the sand facing sun facing direct Well, that's
an interesting question. But moreover, that scattered light, it looks
more like a cigar that is ten times longer than
it is wide, ten times longer than wide. I mean,
we see it mostly edge on because we are almost
the same direction from the object as the Sun is.
(05:50):
But nevertheless we see it elongated towards the sun rather
than away from the Sun. And the question is why.
That's an excellent question. And if it's a natural object,
you might say, Okay, that's the sun facing side is
the warm side, and it sheds ices, and perhaps those
ices evaporate before they have a chance to trail the object.
(06:13):
So if it was regular dust that is made of
refractory elements, it would have survived the sunlight and would
have been pushed behind the object.
Speaker 2 (06:23):
That's why usually you see a tail. But if it's just.
Speaker 3 (06:26):
The fragments of ice, then they disappear and they don't
have a chance to actually go behind the object. That's
one way to explain it. But maybe there is another
way and we just don't. It's the first time we
see such a phenomenon. We've never seen it for comets.
So when NASA or other people, I saw some news
articles saying NASA disputes that it's not a coin, it's
(06:47):
definitely a comet. Well, how do you explain the lack
of a cometary tail and instead the existence of a
glow stretched towards the sun.
Speaker 1 (06:57):
So you're not buying it because you're not a conspiracy
theorist scientists. So you're saying that there's not enough information
to disprove that it's not alien technology.
Speaker 3 (07:07):
Correct, Well, I'm saying there are normally is that. Let
me give you another one that cannot that are not
found in natural objects that we've seen before. Another one
is we observe Nickel without iron. In the plume of
gas around it, it's mostly carbon dioxide, but there is
also nickel but no iron, and usually nickel and iron
(07:29):
come together in nature. In all the comets we've seen before.
The only place where they don't is when we make
industrially nickel alloys, you know, for example, for spacecraft. So
an artificial production of the surface of the object would
have resulted in nickel without iron, and that's what we
see in the gas around it. However, you know, the
(07:51):
astronomers that discovered it with a very large telescope in Chile,
they suggested that maybe it's the same chemical pathway that
we use in our industries that is called the carbonil pathway,
that is making it in nature. But we haven't seen
it before, so that's another peculiar fact. Now the point is,
as we get more evidence about it, it will become
(08:12):
clear what it is. I define a new scale that
is called the lobe scale, whereas.
Speaker 2 (08:17):
The robes scale.
Speaker 1 (08:18):
I've read this and for folks you can go online
and just google the lobe scale and tell us what
this does. Because it was alarming to me as someone
who has been very much Again, I didn't go to
Harvard but someone who very much has been curious why
Washington lawmakers and policymakers around the world are not doing
(08:40):
more to disclose information, why government officials for decades have
not taken these questions seriously. It shouldn't take Paul Revere
for extraterrestrials to sound the alarm. I mean, these are
really concrete questions. And only now that we have the
technology with the telescopes to be looking into these things,
starting to realize that, oh, there's been three in the
(09:02):
last decade, I would I mean again, you would know
better than me. I would assume that those are just
a three that we've been able to find from interstellar
objects in our solar system. So the lobe scale tell
us what it is in very simple, simple terms.
Speaker 2 (09:15):
Yeah.
Speaker 3 (09:15):
So now that we're entering a new phase where the
rubyin Observator in Chile, we'll find an interstellar object every few.
Speaker 2 (09:21):
Months, and every few months every few months.
Speaker 3 (09:24):
It's an amazing telescope that has a camera with three
point two gigapixel started operating just a few months ago.
So when we entered this phase, we should check if
among the rocks that are natural in origin, there might
be any spacecraft. You know any technological object. I define
zero as a definitely natural object like a comet or
(09:47):
an asteroid, and ten as a technological object that could
be a threat to humanity. And so far I give
three I at last, this new object, I give it
a rank of four, but as we get more data,
I may bring it down to one or two, or
up closer to ten. It depends what the data shows.
(10:10):
So just to give you a teaser, on October third,
this object will come close to Mars within twenty nine
million kilometers. And there are lots of orbiters around Mars
that were put by NASA, by the European Space Agency,
but the Chinese Space Agency, and so for example, there
is a high raise camera on both the Mars Reconnaissance
(10:32):
orbiter that NASA put there that would be able to
resolve the object three I atlast, with a pixel size
of thirty kilometers, and that would be a resolution that
is better by a factor of one hundred than what
the Hubble Space telescope could achieve simply because of the proximity,
the fact that this object is coming so close to Mars.
(10:52):
And then you know, if we see that it's a
big object. I mean, currently we don't know its size,
but it could be much bigger than Manhattan Island, and
in that case, it's you know, it's so much more
massive than the previous interested are objects that it could
very well and not be a rock. So let's see
what this telescope finds, what this camera finds. Moreover, if
(11:17):
when it comes close to the sun on October twenty ninth,
so that's just a month away.
Speaker 2 (11:22):
If it's a technological object, it might.
Speaker 3 (11:24):
Maneuver, It may release mini probes that could come and
visit planets, so we will know much more about it,
and we might decide that it's actually a comet, in
which case, don't worry about it.
Speaker 1 (11:35):
You've been so generous with your time. I just want
to take a step back for the last portion of this,
which is the reason I have followed you, is because
you don't say this is what it is. But you
debate and many you do many things, but one of
the things you do is you debate how we even
ask questions and the systems that we even utilize to
(11:56):
deploy answers. Right, the point that you're making is is
that we are not even prepared to ask these questions.
And all you have to do is google the reaction
of how polarizing your comments have been to see that
in many ways you remind me of the scientists and
a science fiction novel. Again, like a Paul Revere who's
(12:17):
been saying, I've been warning you people to ask these questions,
and I just don't think the mainstream consciousness has caught
up to you. What is your point though, I mean,
talk to people like me who really are frustrated that
these questions aren't being taken seriously and aren't even being asked.
Speaker 2 (12:36):
What would you say to people like me?
Speaker 3 (12:37):
Well, first, I should say science is fun because it's
a learning experience. If you are sufficiently modest and humble,
you will be willing to learn something new just by
looking at the data. Don't try to assume that everything
you see is what you already know and know. Or
even though it was said in the Old Testament there
is nothing new under the sun. I do believe that
(12:58):
three I atlas is something new under the sun. Let's
figure out what it is now. The second thing is,
you know, we really need humanity as a whole. It
needs a wake up call because we are currently focused
on conflicts on this rock that we were born on
and there is much more real estate out there. And
you know, we could get inspiration if we find alien
(13:20):
technologies that are far more advanced than what we possess.
It will inspire us to do better to explore space,
change our priorities. Instead of fighting each other, let's work together,
cooperate explore the space beyond the Earth, because eventually, you know,
there would be some catastrophe here on Earth, and we
(13:41):
want to preserve humanity in the long term, and to
think about Darwin's principle of the fittest surviving in the
long term. The fittest is a species that is capable
of escaping from the rock that it was born on.
And you know, perhaps other civilizations did that already because
their star predated the sun. Most stars formed billions of
(14:04):
years before the Sun, and there was plenty of time
for them to.
Speaker 2 (14:07):
Arrive at our neighborhood.
Speaker 3 (14:09):
So they could serve as good role models for us,
those that were successful. And I very much see that
as a sort of an uplifting message for humanity.
Speaker 2 (14:19):
Look up and don't look down on each other. Thank
you so much.
Speaker 1 (14:23):
This is the first of many conversations that we're going
to be having. We cover you extensively on MTF dot
TVs Meet the Future. Thank you for coming on Hello Future.
I will check back in with you later. Thank you sir.
Speaker 3 (14:33):
Thanks Kevin, it was a real pleasure speaking with you.
