Submission + - Is the Universe a Simulation? (phys.org) 2

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.

Is the Universe a Simulation?

  • 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.

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

Nobody said computers were going to be polite.
