Quantum superposition is like a never-ending game of "choose your own adventure" for particles. They're all like, "Hey, I'm a particle, but also I'm not a particle." And you're just like, "Okay, which one are you, really?" But they're all, "Nah, we're all both, man." It's like the ultimate state of confusion, but with math.
So, imagine you have a particle that's both in New York and Tokyo at the same time. And not just that, but also in Paris, Berlin, and Sydney. It's like the particle is all, "I'm a world traveler, but also a stationary observer."
