In the 1930s, the German physicist Erwin Schrodinger proposed a thought experiment.
I’ll spare you the detail, as it was an experiment about quantum mechanics, and quantum mechanics is a bit weird. And it involved a cat, in a box, which may, or, may not, have been alive, or dead, or possibly both, or possibly neither.
But the upshot was this: If you have an equal chance of an event happening or not happening, a cat my or may not be alive or dead.

Schrodinger concluded that, until you actually observe the outcome, the cat is neither dead nor alive, but both.
I told you quantum mechanics was weird.
