Not necessarily, and a majority of cosmologists, according to researcher Leonard Susskind, are leaning in that direction.My perception of infinity is that includes all things. Apparently "things didn't happen until the expansion of the universe. Therefore, as a concept, infinity didn't exist until the universe.
And it may be logical as what we see all the time is a chain of cause & effect that seems never-ending, so why should we conclude that all magically started at just one previous point in time? It would be this latter concept that's actually far less logical based on what we see on a day-to-day basis.
BTW, the vast majority of cosmologists do not believe that there was nothing prior to be BB, instead they strongly have been leaning more to the concept of "singularity" prior to the expansion.
