I don't know if this is science or philosophy, but the idea of something from nothing has been on my mind a lot recently. I've been told countless times that it is physically impossible for something to come from nothing because of the law of conservation of energy, but there's a couple things I don't understand about the whole thing. First, wouldn't the very first something have to come from nothing by default? If it came from something else, then it wasn't really the very first something. Second, isn't it a generally held belief that the Universe will one day end? If so, isn't its energy lost since it no longer has a field in which to exist? Sorry if my question is naive, I tried looking this up before posting, but the only answers I got were religious ones or things along the lines of "Because it can't, that's why."
