I have no idea of the math behind this idea but I thought it was interesting to think about. Say we have a universe like our own in that,and that the following are true: a.Galaxy that are not close enough to have strong gravitational force to each other are moving away from eachother at an expanding rate. b. In some distant time, the clumps of galaxies are so far apart that the acceleration seems to exceed c, ei. that light can no longer be seen of other galaxy clusters, therefore only an observer could only know of there own galaxy cluster. c. Eventually, gravity overcomes the matter and space in the area is contracted to a singularity. Little Bang Could the universe just simple continue dividing itself it smaller and smaller clumps of matter? I see a few problems with this of course. That the big bang was an explosion of space not in space. But it it possible perhaps that within a larger universe a portion of it is contracted to a singularity, or does that not make sense?
