We don’t see the effects of quantum physics outside the submicroscopic scale. But why, exactly, is this true? According to physicists who’ve recently published a paper on that question, the theory of Quantum Darwinism can answer it. Let’s take a look.

The Simulation Hypothesis is the idea that our universe is actually an algorithm being run on a mysterious supercomputer. In a recent paper, a group of physicists say they’ve disproved this theory by using Goedel’s theorem. Let’s take a look.
