We want to understand the rules, or laws of nature, which apply to the universe, but the universe is too complicated… so sometimes we try to guess based on simple experiments, like end games in chess If a rule we guess after watching 100 moves turns out not to work for the 200 th move, we must give up or refine our guess, and keep observing. Nature has the final word. That’s physics!...
