Well
The Many Worlds theory implies that all possible universes are ... possible. Probable even. So it's likely that another universe exists in which our universe is a computer simulation.
If our universe were a simulation in a computer, it would explain a lot of things. For instance, a quantum particle doesn't have to make up its mind until someone performs a read on the location. It would also explain a minimum resolution (Planck length) and clock speed (Planck time). It would also explain why, in regions with a lot of stuff, the calculations slow down because there is more crunching to be done. This explains relativistic time dilation. It explains the speed of light - how quickly signals can propagate across the simulation.
I'm assuming that the simulation runs in a container or a VM. If we could break through to the host or bare metal, then we would have incredible power - time crystals and the like.
And since you ask, yes I have been drinking
