Since there appears to be evidence of multiple "black holes, isn't it possible that we live in a dynamic universe with both expansion and contraction. Perhaps more than one 'bang.' After all, might something like a black hole be necessary to create that ultracompact unity that then expanded into our "universe?"

when we (physicists) refer to the universe as expanding, we mean as a whole. it is true that parts of it are being pulled into black holes, but it seems that the universe as a whole is expanding. It is also possible that there have been multiple creations of the universe.

On a large scale, the universe is increasing. it is properly accepted and measured. On an section scale there is contraction, somewhat with techniques from the demise of stars forming neutron stars and black holes. we may be able to in elementary words talk for the 'seen universe', this is all factors in area-time close adequate for his or her gentle to attain us. We only assume even with is previous it truly is an identical in nature as what's interior. even as the prepare reaches the station, its dense mass of bodies studies a 'vast bang' even as the doorways open, and the mass expands over the community. different mass right now contracts back on the Starbucks for the time of the line. i comprehend of no data that black holes will ever 'bang'. The also variety in personality from what's considered to be the initial mass concentration of the vast bang.
