Is the Universe a Simulation?

olsmeister writes: Ever wonder if the universe is really a simulation? Well, physicists do too. Recently, a group of physicists have devised a way that could conceivably prove one way or the other whether that is the case. There is a paper describing their work on arXiv. Some other physicists propose that the universe is actually a giant hologram with all the action actually occurring on a two-dimensional boundary region.

the universe is:

The universe is something we can't know from the inside of it.

It could be representable as a simulation in 2 or 3 or 4096 dimensions? cool achievement, but no proof.

Take a game of life simulation: from the point of view of the simulation itself you can reason it needs at least N bits of memory to run. Have you proven anything about the infrastructure it is running on? no way, it could be run by hand by a kid, or by the latest supercomputer, from the POV of the simulation you can't tell.

reality is a simulati

So cool..

That's kinda creepy, to imagine that we are all possible living in a hologram.
