Quantum physics. I like reading books about it. But I don’t really understand. Schrodingers cat is in a box. There is a phial of poison in the box with it, but no one knows if the cat us alive or dead unless you open the box. What causes the phial to break depends on entangled electrons…… Which is where I’m lost and can’t remember what I read.
Books I would recommend, that I’ve had for years. In Search if Schrodingers Cat, by John Gribben, and In Search of Schrodingers kittens, by the same author. He also wrote In search of the Edge of Time.
So it’s up to you. It’s a tricky subject, but worth looking into.
