Regardless of whether anything seems random to an observer, it must ultimately be an illusion, not existing at the fundamental level, because there’s nothing random about a mathematical structure. Yet the physics textbooks on my office bookshelves are full of that word: quantum measurements are said to produce random outcomes, and the heat in a cup of coffee is alleged to be caused by random motion of its molecules. Again traditional physics embraces something that the MUH rejects: what are we to make of this?
