It has long been proposed that any civilization of sufficient size and intelligence would eventually create a simulated universe that mirrored itself. Now physicists may have found evidence that our universe is indeed nothing more than a simulation. Researchers at the University of Bonn in Germany have published a paper titled “Constraints on the Universe as a Numerical Simulation” in which they point out that any simulated universe will include limits on its physical laws – boundaries that simulation participants would bump into when they reached an edge of the simulator. As it turns out, our universe incorporates those limits itself. Greisen-Zatsepin-Kuzmin, or GZK cut off, is an apparent boundary of the energy that cosmic ray particles can have (its caused by interaction with cosmic background radiation). The researchers argue that their measurement of these cosmic ray particles is consistent with what you might expect from a computer simulation.
According to Wired Magazine:
“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 to 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.”
In other words, if our universe were not a simulation, cosmic rays should be able to have as much energy as they want. On the other hand, if our universe were a simulation, those cosmic rays would be limited in energy, constrained by the granularity of the simulator’s capabilities.
Of course it could also be that we are incorrectly interpreting evidence of certain fundamental laws that we are as yet unfamiliar with.
