Mind-blowing Overview

More science than you can handle

Episode Transcript

Speaker 1 (00:00):
Hello, listeners of the Internet. I cannot thank you enough
for stopping by. It's time for another episode of Science
Stuff to Blow Your Mind podcast. It usually blows my
mind too. This podcast is dedicated to blowing every one's
mind with science. Today's episode is going to be a scattering.

(00:25):
We're going to try and blow as many minds as
possible with as much crazy mind blowing a science as possible.
We're going to start off to day with something that
I didn't even know was a thing, but I'm sure
glad it is. There is a hypothesis of a holographic universe. Yes.

(00:50):
The holographic principle suggests that our three dimensional reality is
actually encoded on a distant two dimensional surface. This concept
originates from theoretical physics and string theory, with profound implications
for our understanding of space, time, and reality itself. How

(01:16):
did this become a thing. In the nineteen seventies, physicist
Jacob Berkenstein proposed that the information contained in a black
hole is proportional to the area of its event horizon,
not its volume. Later, Suscand and Girard Hoofed expanded this idea,

(01:39):
suggesting that all the information within a region of space
can be described by data on its boundary, just like
a hologram, where a too D plate encodes a three
D image. Here some supporting evidence, the black hole information paradox,

(02:01):
presented by Stephen Cocking, showed that black holes evaporate over
time via Hawking radiation, aptly named. But if they vanish,
what happens to the information inside? The holographic principle provides
a possible solution. Information is never truly lost, but is

(02:25):
encoded on a lower dimensional boundary. In string theory, one
Maldasina proposed a mathematical model where a lower dimensional quantum
field theory fully describes a higher dimensional gravitational system. This

(02:46):
idea strongly supports the holographic nature of reality. What does
this mean to us? Well, if the universe is holographic,
our perception of depth and volume might be an illusion,
similar to how a video game world exists on a
flat screen despite appearing three D. This could revolutionize how

(03:12):
we think about space, time, and even cautiousness itself. If
that wasn't enough to blow your mind, then quantum entanglement
and spooky action at a distance surely will. Quantum entanglement

(03:33):
occurs when two or more quantum particles become linked, so
that measuring one instantly affects the other, no matter how
far apart they are. Albert Einstein famously disliked this concept,
calling it spooky action at a distance. He argued that

(03:56):
quantum mechanics must be incomplete and propose used hidden variables
to explain it. In nineteen sixty four, physicist John Bell
formulated Bell's theorem, which showed that any hidden variable could
not fully explain entanglement without contradicting experimental data. The Aspect

(04:23):
experiment in nineteen eighty two by French physicist Allan Aspect,
who conducted experiments, confirmed that changes to one entangled particle
affected the other instantaneously, even when separated by kilometers. In
nineteen ninety seven, scientists successfully transferred quantum information via entanglement

(04:47):
without physically moving the particle itself. This could lead to
secure communication through quantum key distribution that uses entanglement to
detect ease droppers attempts. Entanglement enables quantum bits or cubits
to perform calculations exponentially faster than classical computers. Next on

(05:12):
our list is the simulation hypothesis. What if our entire
universe is just an advanced computer simulation. This hypothesis suggests
that reality, including consciousness, is artificial and exists within a program.

(05:37):
Nick Bolstrom argued that if technical civilizations survive long enough,
they would create simulated realities. If many such simulations exist,
then statistically it's likely we're living in one. Elon Musk

(05:58):
famously stated that the chance we're when a base level
reality is one in billions. Some aspects of physics, like
the speed of light as an absolute limit, resemble rules
in a programmed environment. Theoretical physicists suggest that space time

(06:21):
might be composed of discrete, indivisible units, just like pixels
in a video game. The observer effect is where a
quantum particle behaves differently when measured. This could be a
sign that our reality only renders when observed. Next up,

(06:48):
what about time dilation and the relativity of time. Turns
out time does not flow the same everywhere. It depends
on speed and gravity. Einstein's theory of relativity dictates this.

(07:11):
The theory of special relativity says that if you travel
close to the speed of light, time slows down for
you compared to someone's stationary. General relativity states that the
stronger the gravitation will feel, the slower time will pass.
There have been some proven experiments. The I Feel keating

(07:33):
experiment in nineteen seventy one used atomic clocks on airplanes
traveling around the Earth. They tick at slightly different rates
than those on the ground, proving time dilation. Similarly, GPS
satellites must adjust for time dilation effects due to both

(07:53):
their speed and weaker gravity in orbit, or else GPS
locations would be off by miles. The implications of this
mean that at near a black hole, time could slow
to nearly a standstill. Theoretically, if we travel fast enough,

(08:15):
we could reach the future while experiencing only a short
amount of personal time. What about the many world's interpretation
of quantum mechanics that says that every quantum decision may
create an alternate reality. This was proposed by Hugh Everett

(08:42):
the Third in nineteen fifty seven. This interpretation suggests that
every quantum event causes a branching into parallel universes. There
is supporting evidence. The double slit experiment saw a single
particle behave as though it passes through multiple paths simultaneously

(09:06):
until observed. This implied multiple outcomes exist. There may be
infinite universes where every possible outcome happens. If true versions
of us might exist where we made different life choices.

(09:27):
If the universes teeming with habitable planets, why haven't we
found extraterrestrial civilizations. This question is known as the Fermi paradox.
It challenges our assumptions about life beyond Earth. The possible
explanations of this is the rare Earth hypothesis, which life

(09:50):
is extremely rare. While habitable planets may exist, the precise
conditions for intelligent life might be exceedingly rare. Factors like
plate tectonics, stable climat and large moon for title stability,
and a Jupiter like protector to deflect asteroids may all

(10:12):
be necessary. Folks. Unfortunately, that's all the time that we've
got for today's episode of Science Stuff to Blow Your
Mind Podcast, a show dedicated to blowing your mind one
episode at a time. Can't thank you enough for listening,
and until next time,
