I think the concept of emergence is something religious people have a tough time understanding.

53. Entertaining idea

I just came by: assuming multiverse, simulated universe is the most likely case, as universes with capability of simulating universes can create simulated universes that can create simulated universes etc - and turtles upon turtles... (and also the simulators in a simulated universe being level up "gods" of the level down simulated universe.)

Some say that such idea might be testable - and hence a 'theory' - assuming no full theory of all behind the simulations and hence observable program glitches (e.g. constants being variables of the simulation program and changing values during the simulation etc). But Chalmers makes a strong case that Matrix simulations and "envatments" are not really separable from theories of physics, as both are based on math, number theory and computability. (http://consc.net/papers/matrix.html)

Also there is strong support for the idea that digital computers would not be enough to do the trick, but quantum computers might be. Strongest support is IMHO the very fact that we have developed/found quantum theory and and quantum computation, and that theory is quite testable, when we manage to build quantum computers complex enough.
