Assume that we have access to a computer with unlimited computing power.
As with the Lattice QCD can try to prove that we live in a simulated universe?
Apparently, one may use the issue of cosmic rays.
If we were living in a simulator, we'd expect to find evidence of that lattice if we looked close enough to the edges of the observable universe - and that's what Silas Beane from the University of Bonn and colleagues have calculated, in a paper published in arXiv. As cosmic particles fly through the universe, they lose energy and change direction and spread out across a spectrum of energy values. There's a known limit is how much energy Those particles have, though, and Beane and his colleagues have calculated That this seemingly arbitrary cliff in the spectrum is consistent with the kind of boundary that you ''d find if there was an underlying lattice governing the limits of a simulator. It should also, if present, scatter the particles in a Certain Way as they come up against it, and the should be able it investigate Whether that's the case.
Do you have any idea?
