WARNING : Please add me to your ignore list if you dont like my random babbles on here. I would like to appologize to those who dont but I have so many questions that I cant figure out how to word that I need to do a random babble once in a while so please stop reading now if you are not into that sort of thing


I was randomally thinking about eternity. What eventually happens in an expanding universe.

At the same time I was thinking about a contracting universe model where parts of the universe are contracting. For example I believe that near a black hole space is contracting.

Then I thought that how can we say the universe is expanding when there are parts of the universe that are contracting.

Then I started to think about what would happen over time.

If the universe continues to expand forever what would happen?

Galaxies would move farther and farther away ( I have questions about this also but lets address that at a different space-time )

however galaxies themselves would eventually be sucked into the blackhole in their center ( is this mainstream??? ).

so we would have a universe of distant blackholes moving farther away from each other.

Then again my question arose as to what is space-time and how could there be nothing in space-time. My understanding is that space-time can not exist without gravity. ( would it even make sense ??? ) So if all we had were massive gravitational forces then how could the universe still expand when their tendancy would be to contract?


The next thought that came into my mind was this:

Picture two funnels connected by the small end ( who knows maybe the big end, maybe both ends ) with stuff flowing from the large end into the small end into the connected small end then out the larger end of the other funnel.
picture this flow in both directions.

As stuff exits either the small end or the big end of either funnel it has to travel at relatively the speed of light.

Now I am not sure but I thought that at the speed of light time stops and that mathmatecally time reverses at speeds past the speed of light. If ther ewas a time reversal ... maybe into another funnel ( either connected at the large end or the small ) it would flow either into the small end or the large ...


I guess what I am saying is that there seems to be some flow into black holes or off the edge of our universe ... at both places it seems that the universe is pulling back time equal to the speed of light ... if on the other end there was another universe that was contracting ( blue shifting ) or time reversed ... then it would absorb from either end and could in theory emmit back into our universe ( or a similar universe ).

OK ... my brain hurts ...
Not sure if any of this is a question but would love if people could correct me where I am wrong.
