If the entire universe expands from a single point in spacetime, and expands in a uniform manner, then the universe has a boundary, regardless how fast or whether or not it’s still expanding. If it has boundaries, then what’s on the other side? One might say that the big bang was/is only the expansion of matter into nothingness. But then the question arises: if, the universe has borders, how did something come to exist in the infinity of nothingness? This gives rise to another question: how do we differentiate nothingness from the near absolute vacuum of deep space? So by deduction, there must be more to empty space if it is to be different from nothingness-if there is nothingness on the outside. i cant make much sens of it. can anyone else?!
