What if your reality is not what it seems to be?

程度副詞

What if you are you're just a 2D projection

stretched on the surface of a black hole?

if everything around us is three-dimensional?

Well, prepare yourself for a big reality check.

Because this unified theory can explain everything

about the fundamental laws of our existence.

We talked about it a little in the episode

your mass increases by the mass of that bagel.

With your mass increased, your volume grows,

and not the volume, that increases with every bite.

It's like the swallowed matter or energy doesn't make it inside the black hole,

Or like if you, instead of eating the bagel,

just taped it to the outside of your stomach.

Black holes themselves are three-dimensional,

but their contents can be projected on their two-dimensional surface.

And that gave scientists the idea of the holographic world.

You, me, and everything else in the Universe

Atoms and molecules are made up of smaller subatomic particles.

And those particles, in turn, are made up of something even smaller -

the information about their state in time and in space.

These particles are so small, that our eyes can't detect them.

And we know they don't answer to the the classical laws of physics.

It's up to quantum mechanics to interpret their nature.

One of the ways to understand the smallest fundamental particles

and the mathematics behind is complicated.

But maybe, we can change the rules a little bit.

If you're trying to solve a complicated problem,

you can map all the volume of the Universe across its boundary.

because, for the two-dimensional Universe,

we don't need to count quantum gravity in.

That turns the nearly impossible-to-crack mathematics of the string theory

you can transform the solution into our three-dimensional space.

Congratulations, you solved the mystery of the Universe

But does that mean we ourselves are living inside a hologram?

When you take a selfie, you lose some of the information about yourself.

The holograms are designed to preserve all of that information.

If you experienced the world in a holographic way,

you could look at someone else's skin and tell everything about their organs,

what they ate for lunch, even their thoughts.

Is it just me, or does that sound creepy?

from black holes, to the smallest particles,

with the help of the holographic principle.

It doesn't necessarily mean we live inside a hologram.

But if we did, we wouldn't be able to tell the difference anyway.
