If we’re an alien computer simulation, could we ever know this?
Religions turn me off. Science turns me on. And in the science books I read, the notion that we could be living as artificial intelligences within a computer simulation keeps popping up. I'm fascinated by this possibility (see previous blog posts here and here). I've finished physicist Brian Greene's new book, "The Hidden Reality." He talks about simulated universes in a Universes, Computers, and Mathematical Reality chapter. My interest here is in those who would be drawn by the purity of electrical impulses to program simulated environments populated by simulated beings that would exist within a computer's hardware; instead of…
