If we are it works really well with a religion/non-religion that's been around for a really long time. It's called Deism. (not theism) I didn't want to hijack your post but on my blog yesterday I wrote a blog called The little religion history has forgotten... Deism have some quotes from Einstein and other famous people. I mention Elon Musk and the matrix stuff at the end.

So I don't see why what you wrote is not possible. I do think it'd be difficult to find out for sure if we were in a simulation. The only way we'd likely ever be able to find out is if we manage to detect the boundaries (not like a box) of the simulation.

How far can we zoom in on particles before things start getting weird? We may have already reached such a place with a lot of the Quantum stuff that we are running into.

The other direction would be how far out can you go.

I kind of view it like it would be if I was coding the simulation. How well can my simulation handle the concepts of infinity both inward and outward.

(none of this last stuff was in my blog... just reserved it for yours)

EDIT: Funny thing is me and friends talked about this at parties in the early 90s before the Matrix. :) We liked inventing different explanations for reality back then as a party gag.
