Hello,(adsbygoogle = window.adsbygoogle || []).push({});

A physics friend of mine said that there is mathematical evidence that the world is a hologram. From what I understand this means that the world is closer to light or the workings of a computer than what we usually think matter to be. However, my question is what math has to do with trying to prove this theory. Math can measure physical motions, but I don't understand how it can be show to prove a theory like this. I also came across a similar theory that said basically if we can create a black hole, this would prove that there are other worlds in other dimensions and that math backs this up. Is the only explanation of this human accomplishment other dimensions? And what has math to do with the demonstration? Thanks very much
