Very interesting Mombat I am out of my depth with all this but I share my views ... Cosmology is not set in stone there is still some stuff to work out so think away...
U]If this is the case then will the black hole at the center of our galaxy eventually engulf the milky way.[/U]
I doubt it but who knows.
I think that black holes clean out the material available to them and observations I have read support this.. but it suggested to me that the influence of the black hole in effect left an eaten out region. AND I think a black hole has little gravitational influence outside that region ...but my point is, it therefore seems not a case where stuff is banked up waiting to drop in....which does not present a picture of eventual disappearance of the galaxy down its own black hole.
Is the great attractor to which our own local group, and supercluster is speeding towards an enormous black hole which will engulf our galaxy or perhaps by then our milky way black hole.
Well at those scales it is difficult to image it is attraction that is producing the move we observe... without doing the sums I bet we would find difficulties in determing attraction is doing all we observe... for mine to understand what we observe I feel we need an extenal influence at the scales you mention... pretty big...in fact very big... consider the distance spread for the region that appears related and then how any message of gravity could produce such unison...maybe it is dark energy that is holding all of that in place but I think there may be a problem in establishing gravitational relationships and explain them using current theories.
Sorry my mind is not in gear yet.
If this is the case could that be what our Universe ends up being a series of immense balck holes seperated by distances beyond which gravity cannot over come the expansion of space time.
Well one of the reasons I like push gravity ...is gravity will always rule and not see the Universe you consider.
I can not consider that the Universe will "suck" all matter to certain spots (black holes) such that the voids that remain are absent of all forces....and if you think it through that is what your hypothetical can only lead you to. The black holes will have all the matter .... mmm if nothing can escape a black hole how does the message of gravity make it...is that not curious?
Whatever the voids that remain maybe they will have no light or gravity... in fact nothing in the absolute meaning of the word. Sounds silly but that is to only result if we extrapolate to a situation where there be only black holes...what else can be on their outside??
Still if we consider what came before the BB maybe where you are going is correct...maybe finally all the black holes gather into one (man how long for everything to come home to unite as one) and as one we have a new singularity to set the seen for a new BB... if it is to go this way even starting right now how long would it take the universe to finally colapse...with out a reverse inflation theory ...trillions of years to the power of 50... so we are either very young in the scheme of things or its never going to happen...
Bearing in mind that i am talking about a timeline of several times the age of the current universe.
Take some time to think about ruffly how much time... first how big is the Universe at the moment...well we get all figures from infinite (forget that if using the big banf model) to about 160 billion light years...I dont know if that is the diameter of us as a sphere or a disk or what but just think using the force of attraction to bring all that back to one place with take "ages"...but as we observe the universe is still expanding so we would be looking at some time before we even saw a turn around....maybe the great attractor is a sign that the tide has changed
...you may have something here
...dont worry about a longer time line than you feel comfortable with just work out how long that time line may be... ruff of course.
That was confusing even to me.
Well you are embracing interesting concepts and this is not the stuff one brings up when chatting about the footy so dont worry..and you seemed very lucid to me.
