I guess I'm quite dumb, because what I can't get my mind around are black-holes. I don't know very much, but still I find the sky inspiring. I don't know at what rate this said increasing rate is at, or if ... it can exceed that of light ... if gravity is ultimately stronger than light, via black-hole, how could anything ever really expand to begin with, unless like there is something that can trap light, there is something that can accelerate it?
I find it very strange indeed, some shows I have seen, professing that quite possibly black holes are not the abnormality they were once thought to be, but much rather ... the more common opposite. And like mega hurricanes, tornadoes, and volcanoes ... there are even mega black-holes looming in the hub of galaxies! Holy yin-yang Batman!!
Would there be a mega-ultra-ginormous black-hole at the center of the universe? How did anything ever escape it? Would all these black-holes eventually collect each other and everything, or just everything in their way as the are pushed ever outward by something with a greater effect on gravity, over that which swallows light?
To me the question almost seems like saying, how big or small is infinitely ... either. Could it work both ways? I think of the "universe" like bubbles ... some expand till they pop, some cave in on themselves, like stars .... and there is seemingly an unquantifiable amount of them like stars ... did, does, will, the big-bang ever stop? Do black holes .. ever ... stop? How many of them are there? My little brain is about to pop, I'll stick to science-fiction.
I admire the hunt for more, and can only suggest that we simply do not have enough data, or the right kind, if we know what that is.
