Everything, apparantly, gets to a point where it can be rounded off to zero, so therefore it doesn't exist, but some numbers get to one, meaning that everything that 'exists' is a collecrtion of ones and zeros, just like binary code, which is quite an irritating thought, because if I just made a mistake, and everything is a zero, it means that nothing exists, but if I was right, and everything is in binary, then the most likely explanation is that we are all in a computer simulation.

That's Quite a depressing thought, so nothing really exists.
but what if all that's in an even bigger simulation, and could go on to infinity, or possably run in a massive circle, ful of simulations, each in a simulation that is run by another simulation, and eventually going round to the beggining again, which would still mean that nothing really exists, we're not thinking, this web address isn't real, nothing whatsoever is real
