We are a computer simulation that has created a computer simulation of what things would be like if we were a computer simulation. That seems to be what these people are saying. There apparently is a belief that any good-sized civilization competent enough to do so would eventually create a simulated universe. Since the only logical place this thought could go to would be that this simulation would then create other simulations it is more likely than not that our world is not what it seems.
A group of researchers at the University of Bonn In Germany claim to have evidence that this is true. They point out in a paper named ‘Constraints on the universe as a numerical situation’ that current computer simulations naturally put limits on physical laws. They claim that a simulated universe would have an “underlying lattice construct” that would put a limit on the amount of energy that could be represented by energy particles. Silas Beane, the led scientist, and his team say they have found that there are limits very much like those that exist within our universe. One example of this that is being passed around is the Greisen-Zatsepin-Kuzmin limit. According to the Wikipedia definition this is the “theoretical upper limit on the energy of cosmic rays (high energy charged particles from space) coming from “distant” sources”. “The limit is set by slowing-interactions of cosmic ray protons with the microwave background radiation over long distances.”
This could possibly explain other dimensions. Since the idea is that any civilization would eventually create a simulation, even if that civilization is a simulation, then there is an infinite number of simulated universes floating around out there. Could it then be possible that at certain points universes could overlap? Could that be the possible cause for places such as the Bermuda Triangle?
