Holographic Universe? Are we living on a hologram? Or inside a black hole? Our perception is that we live in a three dimensional world. What if our three dimensions, can be equally represented on a two dimensional surface? Does this mean we live in a hologram? Or could we be inside a black hole? To understand the idea of the holographic universe, we have to start with two things, a black hole, and Stephen Hawking. A black hole is an object with so much gravity that even light cannot escape it. Near a black hole, there is something called the event horizon, that is the point beyond which light is stuck, it cannot escape the gravity. Space itself is falling inside the blackhole at the speed of light. The event horizon of a black hole forms a sphere around the black hole. We don’t really know much what happens inside the black hole. Things falling in seen to leave our universe and end up elsewhere. Stephen Hawking, in 1981, proposed that this event horizon may be breaking one of the fundamental rules of physics - conservation of information. He showed that things that fall into the black hole seemingly disappear from this universe forever, that information is destroyed. This is the information paradox. How is information destroyed? You can burn a book. Doesn’t that destroy information? Not exactly, the information is still available in the universe. If we had the right quantum tools to recapture all the energy and matter from the burning process, we could theoretically put all the information back together again. Nothing is lost in terms of quantum mechanics. Stephen Hawking was saying something different. This was so earth shattering to quantum physicists. Two physicists that were shocked by Hawkings paper were Gerard t’ Hooft and Leonard Suskind. They proposed a solution to the information paradox, and in 1997, Argentinian physicist Juan Maldecena, put it in very precise mathematical terms. What they showed is that even though infor
