My view is that matter and energy has always existed, and did not appear out of a vaccume or nothing. Space itself may have infinite volume, but there appears to be a finite amount of matter and energy within this infinite space.
The big bang implies that all matter and energy at one point was condensed into a singularity that exploded scattering the finite amount of matter and energy through out infinite space.
I imagine we have this expansion, and gravitational centers form as matter starts to recombine into stars and black holes. Eventually certain points within the Universe will start to form massive gravitational points causing a retraction of matter into these centers as they start to consume all matter.
This form of gravitational decay eventually starts to slow expansion and the intensity of these super gravitational systems, black holes will eventually recombine to one massive point in the Universe that will become the new point of singularity where by everything will swirl around like a toilet flushing in this final vortex and the singularity can form once again.
Another big bang, and the process could repeat for infinity. If this is true, we might be able to calculate the time of expansion, the collapse of systems into gravitational hot spots, the recombining of these hotspots into a massive center.
It may take 37 billion years, 109 billion years, I am not sure how to calculate that math because I really don't know the finite volume of matter vs the gravity it creates to affect the current expansion into contraction. I'm sure someone will get it if it's true.
