Ah, yes. The simulation hypothesis. Now - as scary as this sounds - the sad truth is that being in a simulation would solve many physics mysteries in our universe today. Quantum indeterminacy? Check. The Many-Worlds theory? Also check. The upper limit on the speed of light? Well, unfortunately, that's also solved by our beloved simulation hypothesis. (Don't worry, though, just to keep things level, we'll also tackle why this theory is so controversial in the first place.) So sit back, put on your seatbelt, and enjoy your ride - it's going to be a freaky one.
