Is the Universe a Simulation?

The Matrix 2

olsmeister (1488789) 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: (1)

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 simulation vs. reality is real? No difference between the two. Reality is, by mere definition. Or even better, I am, by definition. I am part of reality or imagining it as a corollary. Sum, ergo cogito.
