SchrÖdingers Cat is silliness. The cat is in fact alive or dead, one or the other, wether you can see/know it or not. A=A

That's what Einstein thought too, and he spent the second half of his career trying to disprove the theory of quantum mechanics. But Einstein was wrong. Physicists have known since the 1950s that all elementary particles in the universe exist in multiple states at once, until it is measured of observed, then its superposition collapses to a known state.

Schrodinger's cat really is dead and alive at the same time until someone or something makes an observation or takes a measurement. Quantum mechanics is best described as: "the moon doesn't exist unless a mouse looks at it."
