For the moment, we're going to pretend that we actually have the ability to explain this in a way that is not insane.
Back in Einstein's day, Big Al and his colleagues discovered a problem: The laws of physics didn't seem to work once you got on a subatomic scale. In fact, even today, no one has been able to marry Einstein's theory of relativity with quantum physics, and not for lack of trying. One attempt you might have heard of is string theory, which simply suggests that once you get smaller than an atom, everything is a string. Specifically, a 2-D unit called a quantum string. So far, so good? FANTASTIC.
Above: String theory. Apparently.
Now. String theorists think that everything we see, feel, hear, touch, taste and screw is nothing more than the vibration of those strings, a theory so far out there that string theorists are known as the Cheeches and Chongs of the physics world. Holographic universers took that theory further by suggesting that maybe, just maybe, everything we feel, hear, touch, taste and screw could be a 3-D projection of cosmic data encoded on a 2-D surface.
