Do we live in a simulation?

 Nah, really. Read this first ...

Do we live in a simulation? Here's why we may never know. (msn.com)

Pretty radical idea. But not really.

First of all, there is some pretty compelling 'evidence' in the apparent quantization of many physical things, at least in theory. For some phenomena we know a lot (electron states) and for others we know little (entanglement).

Simulations, at least as we know them, are digital and ruled by mathematics.  Physics, essentially, is ruled by what can and cannot be. Things that cannot be proven to be impossible are therefore possible.

Now here comes the interesting problem, at least in my mind. Many people believe in a God or Spirit of some sort. I am that way also but more Universalist. Is that not possibly a translation of a longing for the programmer of the simulation?

Now before I get into the metaphysical, let me drop one more bombshell. Maybe the illusion of self and reality that each of us has (even animals and plant) constitute the many worlds? Perhaps this is how the simulation works out?  

Now this is of course just conjecture. But an interesting thought experiment. Is such a thing possible to know and so what?
