In quantum mechanics, superposition is the state of being in multiple places at once. Sounds fun, right? It's like being in multiple places, but not really. Like, you know, you're not really in any of those places. But you're kinda in all of them? Maybe?
It's like, have you ever been to the beach and the park at the same time? Nope, just us.
Or maybe you've been in two places, but not really. That's quantum superposition for you!
