Superdeterminism

Superdeterminism is an idea that says that everything that happens in the universe has been determined - or caused - by events that happened in the past. It suggests that no matter what you do, the future is already set and there is nothing you can do to change it. For example, if you throw a rock, it was already decided before you threw it which way the rock will go and where it will land. This idea might sound a little confusing but it's similar to the idea that a movie is already made before you go to the theatre to watch it. The storyline is already written and nothing you can do will change it.
