So if I understood correctly, Schrodinger's Cat is a thought experiment that puts a cat inside a box, and there's a mechanism that kills the cat with 50% probability based on a quantum process. The argument is that the cat now must be in a superposition of dead and alive. But, is the cat really in a superposition?
This is my argument against superposition. Say someone drew a line and said to measure it. When you look at the line, you don't know how long the line is until you measure it. The line can't be different lengths, it already has a defined length. So if you don't know the spin of a particle until you measure it, it's like not knowing the length of the line right? My question is, is a particle really in a superposition before we observe it? The spin may be unknown, but it's still has a defined spin right?
