Mind-blowing Overview pt2

More science than you can handle con't

Episode Transcript

Speaker 1 (00:00):
Hello, listeners, I cannot thank you enough for stopping my
of for another episode of the Science Stuff to Blow
Your Mind podcast, a show dedicated to blowing your mind
with science. And you should be aware that today's episode
is a continuation of last week's episode. If you didn't

(00:24):
catch last week's episode, you want to go back and
check it out. We started a general overview of mind
blowing science stuff. We talked about the fact that we
may actually be living in a holographic universe. We talked
about quantum entanglement. We talked about the simulation hypothesis. We

(00:51):
talked about the many world's interpretation of quantum mechanics. Folks,
it was a lot in one episode. Today's episode, we're
going to talk about possible explanations of the absence of aliens.

(01:14):
I know you've seen Star Trek and Star Wars and
all the other space shows. There should be aliens all
over the place, but there's not. There is the rare
Earth hypothesis. It says that life is extremely rare. While

(01:37):
habitable planets may exist, the precise conditions for intelligent life
might be exceedingly rare. Factors like tectonics, a stable climate,
a large moon, for tidal stability, and a Jupiter like
protector to deflect asteroids may all be necessary. There is

(02:03):
the zoo hypothesis that aliens are indeed watching us. Advanced
civilizations might be deliberately avoiding contact, observing us as we
would animals in a zoo. Earth might be a big zoo.

(02:25):
As a matter of fact, some theorists suggest they may
be enforcing a cosmic quarantine until humanity reaches a certain
level of technological maturity. That's a euphemism, if I've ever
heard one. Humanity just needs to be nice. The Great

(02:50):
Filter states that something wipes out intelligence civilizations. This concept
suggests that somewhere along the timeline of evolution there is
a nearly insurmountable barrier that prevents most civilizations from reaching
interstellar expansion. If the Great Filter is behind us, meaning

(03:15):
life rarely evolves past single cell organisms, we may be
among the first intelligent beings. If the Great Filter is
ahead of us, then advanced civilizations inevitably destroy themselves by
nuclear war, ai catastrophe, or environmental collapse. If this is true,

(03:44):
we may be doomed. The next topic to blow your
mind black holes, Yes, yes, but what about white holes?
Black holes are among the most mysterious objects in the universe,
But what if they have posits white holes that spew
matter and energy instead of consuming it. Black holes form

(04:09):
when massive stars collapse under their own gravity. Their core
becomes so dense that nothing, not even light, can escape.
The boundary surrounding a black hole is called the event
horizon point of no return. Mathematically, general relativity allows for

(04:31):
white holes regions of space time that can never be
entered but constantly emit energy. Some theorists suggest white holes
might be linked to black holes via wormholes. That's a
lot of holes. These would act as exit points in

(04:52):
a different part of the universe or another dimension. If
this is true, a black hole could be a portal
to another universe. This is not science fiction, folks. Some physicists,
as a matter of fact, propose that the Big Bang

(05:13):
itself was a massive white hole explosion. Instead of forming
from a collapsing star, it could have resulted from matter
escaping from another universe's black hole loop. Quantum gravity suggests
that instead of a singularity inside of a black hole,

(05:35):
there may be a bridge to another universe. If this
is true, then every black hole could lead to the
birth of a new cosmos. The next topic to blow
your mind is the mystery of dark matter and dark energy.

(05:57):
The maturity of the universes made up of stuff that
we can't see and don't understand. Think about that for
a minute. When astrophysicists observed galaxies, they notice they spin
much faster than expected based on their visible mass. Something

(06:20):
unseen dark matter must be adding extra gravity. Possible candidates
for dark matter include whimps, weekly interacting massive particles. These
are hypothetical particles that barely interact with normal matter. Axions

(06:43):
are tiny ultra light particles that could explain dark matter
in primordial black holes are tiny black holes formed in
the early universe. Observations of distant supernovae revealed that the

(07:04):
expansion of the universe is accelerating, meaning some unknown force
dark energy is pushing galaxies apart. It makes up sixty
eight percent of the universe. Possible explanations for dark energy.

(07:26):
The cosmological constant was proposed by Einstein. It suggests space
itself as energy that causes expansion. Quintessence is a dynamic
evolving the field that influences cosmic expansion. Some suggest dark

(07:51):
energy effects are caused by interactions with parallel universes, thus
having a multi influence. If dark matter and dark energy
turn out to be misinterpretations of gravity, our entire understanding

(08:13):
of physics may need to be rewritten. Next topic is
planked time, the smallest unit of time. How small can
time get? Is reality continuous or does it operate in

(08:39):
tiny indivisible chunks? The planked scale is where physics breaks down.
Planks time tend to the minus forty third power of second.
That's really fast. Is the smallest meaningful measurement of time.

(09:06):
Below this scale, classical physics no longer works, and quantum
gravity effects dominate. Time may stop existing. If time is quantized,
it means that time doesn't flow continuously, but in discrete ticks.

(09:31):
Reality may be pixelated. The universe could be made up
of fundamental units of space time like pixels on a
screen quantum foam. Yes, you heard that correctly. At tiny scales,
space time itself may be turbulent and chaotic, constantly fluctuating.

(09:58):
The implications for black holes and the Big Bang is
that if space time is discreet, it could solve the
black hole singularity problem, where equations currently break down. The
Big Bang may not have been a singularity, but a
quantum fluctuation from another universe. I know my mind is blown, folks. Unfortunately,

(10:28):
that's all the time that we've got for today's episode
of science Stuff to blow your mind. I can't thank
you enough for listening, and until next time,
