All States at Once

Superposition means a quantum particle exists in all possible states at once until measured. An electron doesn't have a definite position — it has a cloud of probabilities.

This isn't ignorance. The electron genuinely doesn't have a set position until something forces it to commit.

Schrödinger pictured this with his famous box: a cat sealed inside with a device that has a 50% chance of killing it, triggered by radioactive decay. Until you open the box, quantum rules say the cat is in a superposition of alive and dead. He meant it as a criticism — he thought that conclusion was absurd.
