"The details are complex, but the basic idea is simple: Some of today’s computer simulations of our cosmos produce distinctive anomalies — for example, there are telltale glitches in the behavior of simulated cosmic rays." I would like to know more of the details.. But, surely we can't use knowledge of physics and computer-science from simulations we run in our simulated universe, to make predictions about the simulation we are in, which is running in the universe above us, which may have utterly different physics, even logic, and ways of doing computation? The the idea just immediately seems paradoxical to me.
