I am not a university student. I am just in high school but am studying physics and chem. I am just sitting here wondering why do we have energy. I mean look at computers communication there is 0 and 1. on and off. Off will always be a granted but why is there an on. nothing has a purpose because for something "not to be real" makes more sense, because It is nothing (empty) there is no reason for it to exist. but for things to exist makes zero sense.
So if energy can be off why do we have
