I can't even properly explain this because were going into metaphysical territory which is nonsense. In this universe there is time and space. Because of time and space the universe operates based on the law of cause and effect. Every action has a reaction etc. We know that the big bang created time and space, otherwise.......we wouldn't be able to record the universe as starting 14 billion years ago. It would mean that wherever there "is" time, it has to be within this universe. And is therefore measurable and applicable to our understanding.
I agree with what the above person stated read up on physics and quantum mechanics there's a lot of questions and shit to be discovered and who knows who'll make the next massive leap of understanding.
