Sir/Ma'am I had previously asked a question of "where exactly does the space expand into....." I received an answer -if space was infinite it wouldn't be expanding into anything because it was already infinite .. But( to the best of my knowledge), i feel that I could simply rule out the space being infinite because- If we had started with some amt of matter then to spread that in an infinite area we would require a density (of space) to be zero exactly , however we even in vaccum find some or the other form of atomic and/or subatomic "substance".... You can object me by telling that we had started with an infinite amount of matter but then we should have a density of exactly 1 unit because -infinity by -infinity=1 Which is not the real case .. What now ,is this some sort of a paradox
