This theory about quanta, the building blocks of all matter, was fine and good until physicist Erwin Schrödinger pointed out that it doesn't make sense in reality. He asked what would happen if a cat was in a box that was set up to release poison and kill the cat if a quantum was fired at it and hit a certain spot. If quanta don't gel into particles and therefore are unable to 'hit a certain spot' until we observe them, and we fire one at the box, what happens to the cat before we make our observation? Is it dead or alive, neither or both?
He was saying that contrary to quantum theory, reality must exist independent of our observation of it.
Reality, therefore, does not condense out of the realm of all possibilities into one point in space and time until we observe it.
Very simply put, this theory is the scientific way of saying existence is mind over matter.
