If you're interested in going a bit deeper on this, Nick Bostrom ( http://nickbostrom.com/ ) has pulled together an intriguing case: http://www.simulation-argument.com/simulation.html A provoking question: if we found evidence that convinced us, beyond a reasonable doubt, that we were living in a computer simulation, would you change your behavior?

Could you?

Already have!

I really hope they don't accidentally trigger a divide by zero error and we have to start over again.

I'm sure they do checkpointing and can roll back in the event of a problem. This has probably happened many times already.

Checkpointing does require a lot of resources and very large scale simulation like a simulation of whole universe may prohibit such checkpointing.

Earlier quoted context omitted.

Imagine if you not only realized you were living in a simulation but that the simulation involved randomness (god playing dice) and you could somehow force backtracking with a simple button so that different values were chosen. Now, play the lottery and hit that button whenever you don't win; you could then surface an unlikely universe where you get really lucky.

It's unlikely to work unless the button is so reliable that you have a better chance of winning the lottery than the button/mechanism failing in some (possibly undetectable) way. It's the same argument against trying to use quantum immortality to force a miracle by killing yourself, or constructing a machine to kill you, unless some desirable event occurs. It's much more likely that your machine will fail, or you'll…

We could imagine that the simulation naturally backtracks given a paradox or dead end. So if the lottery is rigged, I would never get rich, and the simulation would just backtrack to where I would never decide to try this.

If we were created like this, wouldn't it be feasible to say that the creators could just patch this up so the experiment will appear to work but is indeed, rigged.

Could? Probably; depends on the nature of the simulation.

Would? If they could, they might, or they might be pleased we figured it out :-P

That depends on the scales involved in the universe where the simulation is being run. Maybe we're easy :-P
