Schrödinger’s cat is a physics thought experiment that postulate that a cat inside a box could be either dead or alive, but that state can only be determined by looking inside the box. Until you look inside that box, the cat is neither dead nor alive.
The basic idea behind Schrödinger’s cat is that an object can be in multiple positions and states at the same time until something snaps them in place. However physicists believe that gravity is not responsible for determining the fate of Schrödinger’s cat.
That’s good news for all cats but that still fails to answer the question on why someone put Schrödinger’s cat inside a box in the first place?
