Are the various physical limits of our universe (e.g. the cutoff in the amount of energy a cosmic ray can have) evidence that our universe is the creation of technology with limited capabilities? Huffington Post explains:
A long-proposed thought experiment points out that any civilisation of sufficient intelligence would eventually create a simulation universe if such a thing were possible. Since there would therefore be many more simulations (within simulations, within simulations) than real universes, it is more likely than not that our world is artificial.
Now a team of researchers at the University of Bonn in Germany say they have evidence this may be true. They point out that simulations of the universe naturally put limits on physical laws. By just being a simulation, [a] computer would put limits on, for instance, the energy that particles can have within the program. These limits would be experienced by those living within the sim – and as it turns out, something which looks just like these limits do in fact exist.
For instance, something known as the Greisen-Zatsepin-Kuzmin, or GZK cut off, is an apparent boundary of the energy that cosmic ray particles can have. This is caused by interaction with cosmic background radiation. But Beane and co’s paper argues that the pattern of this rule mirrors what you might expect from a computer simulation.
