Ask HN: Assume the universe is a simulation. Why is c the speed of light?

If you were to reverse engineer the universe from your observations, what would you say is the significance of the speed of light?

I'd say it's the clock-speed of the processor. The rate at which the universe ticks, always constant.

Or perhaps they used a primitive MAX_SPEED that can't hold anything larger than C.

I'd say it's a hack, and so is the whole quantum "you can't find both momentum and position of a particle" thing. There's something weird about the Simulator's 256-bit computer that we're running on that makes a constant C and some quantum physics oddities run faster. They didn't think it would matter, but we figured it out.
