If there had been a lot more matter then all of space would have been consumed (and time ended) in the The Big Crunch. However, the Big Bang, Inflation and Dark Energy have all been having a field-day generating new space (i.e., diverging spacetime) such that the nibbling of matter doesn't really matter all that much.
Thanks for the encouragement, Neufer .. can you tell me why a Black Hole is said to increase in mass when everything that enters it is said to go into a singularity .. which as I understand it at this point is a mathematical point only .. having no mass at all. Or is my current understanding completely wrong? (As it could easily be as my most recent reading easily points out that singularities are a very, very, very complex topic.
Art spun up an artfully obtuse "answer" which was true, but failed to directly address warming3
's question, so I'm not copacetic
with just leaving this alone. A very important principle of nature is conservation of energy. Energy (matter is made of energy, E=mc2
) that enters a black hole is not lost to the universe, it adds to the three (and only three) properties of a black hole that can potentially be observed from the outside; mass, electric charge, and spin, aka angular momentum. There is no reason to believe that a BH's singularly has "no mass at all". But, otoh we can't even say for sure that BHs really have singularlies at their cores.
Was that helpful?
Copacetic... certainly one of the most adorably abstruse words of the English language!
Bruce, I quite agree with you that there is no reason to believe that a black hole's singularity has no mass at all. I would think that while the amount of mass in a singularity simply can't be infinite, it might, indeed, be infinitely compressed!
Art, if time and space would have been utterly consumed in a Big Crunch, does that mean that time and space was regurgitated by the Big Bang?
Or would it be more accurate to think of the Big Bang as a tremendously fertile womb, nurturing the beginnings of the universe inside its near-infinitely tiny uterus, and then explosively bringing the baby cosmos forth in a matricidal parturition of the universe?
