ELI5: There's a theory that states that free will is an illusion - explain ?
gpt
Think about the universe, and everything that has happened since the Big Bang, as a pool game. The pool game is huge and super complicated, but the truth is that the behavior of all of the moving parts was determined by the way the break happened on the table. Everything was set into motion by that original input, and so everything that happens was predetermined by that, and if you could understand the break in enough detail you could guess where everything was headed, and where it would end up. Free will is an illusion, because we live in a deterministic universe and every choice you make can be explained by looking at all the events that led up to now. Or at least some people think.
