Could the Big Bang Have Been A Cyclical Event? I am a layperson...this is a long-pondered question. Is it possible that Black Holes serve a greater purpose...to facilitate a massive contraction...which will then lead to another big bang? It's logical that the Big Bang was precipitated by a contraction. It would explain the consistency of matter. All matter could have been mixed together in a single contractive gathering of massive black holes...reached a critical point and exploded outward. The explosion could have also created new and smaller black holes...that would continue to grow as they travel outward (also - are all black holes shaped the same?). If the black holes could become massive enough they could re-gather and the cycle could be repeated infinitely. The question is this...as the Big Bang started with a finite quantity of mass...and continues to expand infinitely...would there ever be enough mass concentrated in expanding and outwardly travelling black holes that would allow a re-contraction? Or, is the space/time of expansion too great to provide for a gathering and re-contraction? How can this be calculated...at what distance will/did a re-contraction become impossible?
