This have been bugging me for a long time.I am referring this to time, not vacuum, etc.Our perception of time may be false but lets put that aside and think about it. To people who think time doesnt exist: lets just say time exists, and think about before the big bang.Mathematics is also a concept people made in order to benefit society, just like time, etc. Just like any other tool, it helps in our everyday life.This infinity thing is not going to help our everyday life but its intriguing so if you have any idea on this kind of matter, share with me. Someone said this concept is like a circle, no start no end. But someone may ask where did the circle come from. It could just be our brain that is programmed to think there is a start, or the person answered may be right.What are your thoughts on this matter?There are things in life which we may not be able to conceptualize but that doesnt mean we shouldnt try to understand it.Something cant come from nothing, nothing is a human concept, there cannot be completely nothing, because energy may have been always existed, that is why i asked this question.A lot of physicists are coming up with theories why this whole thing 'began'. Again, i believe absence of everything is nonexistent, same logic as what i mentioned above.I believe in multiple universe theory, i think its plausible but i dont think it should be categorized as something 'infinte' because it doesnt seem like a right term to use.Seems like you are talking about cyclic universe theory thing, i dont think that makes sense, it lost its credit when dark energy was introduced, how can the universe suddenly shrink when the expansion is accelerating? Gravitation 'potential' wont be able to overcome dark energy. Again, i dont believe pure 'nothingness' exists.
