So what's the tickrate for nature's physics simulations? I want to see it one tick after inception.

That would be a Planck time, but 1) we can't measure with a precision anywhere remotely close to that, and 2) if we could time things that finely, we couldn't take a photograph of it because there isn't enough time for the photons to hit your receptor. For perspective, this photo took more than a decillion Planck times.

(Disclaimer: I'm not a physicist of any sort, but I'm pretty sure this is all right.)

I might be wrong but I think it's this: http://en.wikipedia.org/wiki/Planck_time

...which if my math is right, comes out to 1/100,000,000,000,000,000th of the amount of time post explosion of this photo...

I don't think it would like much!

its really interesting that a discrete time unit exists. Perhaps this could be construed as evidence that the world we live in is actually a simulation.
