As crazy as it sounds, the entire universe - including you - could just be a hologram. And here's the science to back it up.

Information is basically the mathematical term for matter, basically the arrangement of the atoms and subatomic particles and their position in spacetime.
So we know that information including light is sucked into a black hole at such a rate that nothing can escape it.
But where does it go from there? According to our favorite half/man, half/robot, it basically ceases to exist.
Which violates some pretty serious laws of physics, especially some quantum physics.
Because a fundamental law of quantum mechanics says that information is encoded into the wave function of subatomic particles, which according to the rule of unitarity, means that information is conserved in the quantum sense.
In other words, information has a mathematical copy in the quantum world, so no information can ever really be lost.
But general relativity, which Hawking specializes in, says that the information is lost.
And that became known as the Hawking Paradox. Because when you’re really smart, you get to have things named after you.
So along came Leonard Suskind, a quantum physicist who had his own idea about black holes.
Coming from the quantum side, he postulated that all the information doesn’t fall into the black hole at all, but instead gets encoded into the event horizon and what falls into the black hole is a projection of that information.
Kind of like the surface of the black hole is a film strip, and it’s being projected into the inside.
Now, I need to say, this involves math far beyond my pay grade… and abilities.
But suffice it to say, Suskind was able to back this up with math that showed this could be possible, effectively tying together Relativity and Quantum mechanics.
This means that inside a black hole is a perfect projection of what’s on the outside. So there’s 2 of everything.
If you were living inside a black hole, you would never know that you were just the projection and the real you was up there somewhere.
Which leads to the next obvious question… Are WE just a projection?
How do we know whether we are real or the copy? There’s absolutely no way we could possibly know.
So the idea was met with a healthy amount of skepticism. Still, it was solid enough that mathematicians got to work to perfect the theory. And someone cracked it.
Juan Maldecena mathematically proved the holographic principle in what he called the AdS/CFT correspondence, the conjecture about the equivalence of string theory on anti-de Siter Space, and a conformal field theory defined on the boundary of the AdS Space.
So with the math in place, the holographic principle won out, leading even Stephen Hawking to concede, saying that going against it was one of the biggest blunders of his career.
