Are we living in a simulation?

Things that might suggest the universe is a simulation:


1. Accelerating expansion of universe suggests non-cyclical nature of universe (i.e. the simulation started at the big bang)

2. We've yet to discover physical "stuff" -- so far it's rules & information all the way down.
- Counter-argument: would physical stuff look any different to this? Would we know it when we saw it?

3. The apparent inaccessibility of "hidden variables" in quantum physics. Perhaps there are causal mechanisms behind the apparent randomness of wave collapse, but these might be inaccessible within our universe.
