I feel swayed by the passion but unfortunately can only say I dont go along with your model

.. dont be put out because yours is not the only one

.. but it is interesting, conceptually tidy, reasonable without going into detail.
I think the observed expansion may be inconsistent with the prospect of black holes eventual consumption of everything.
In your Universe one would expect the Moon to be getting closer to the Earth not moving away... maybe its being pushed away or is following a bend in space time I dont know but in a cycle such as you suggest it would seem the Moon could be orbiting closer as time passes.. to speed up the black hole gobble up in an efficient manner...the Earth doing the right thing and merging with the Moon for a take away down the track... maybe.
How will the black holes gather up the last bit of Hawking radiation prior to demise or rebirth ... reverse inflation?
I dont know if the Universe will die, but I dont believe it will.. drawing the conclusion it will die is only supported by the big bang notion and the influence of human experience, ...
I once thought black holes were gravitationally relevant to the galaxy but it seems their mass is so relatively small they have little relevance.
If there are any at the center of our galaxy they must orbit the galaxy centre and not be at the galaxy centre... such is their insignifficant gravitational influence on the galaxy... under an attraction system or a "push" system I think the numbers suggest what I see.
The vast out flow of material from the center of a spiral galaxy makes me think a different system is responsible other than the suggested resident black hole shooting matter out of the galaxy.
And how does this out flow of matter fit in to the galaxies lining up like buttons on a string I always wonder... if a black hole is relevant it must provide a reason for its part in the apparent passing of material between galaxies on the string. Why is material cast out of the gallaxy I wonder.
And in this context why does the black hole reject any matter at all and not consume the lot. I know the same as a comet being flung out the back.
The biggest black hole believed to exist will only form a very small part of the total mass of a galaxy , can a black hole consume an entire galaxy? if so how long will it take, say for the Milky Way? Can we have a black hole the mass of approx 300 billion Suns? Now that would bend space time beyong repair.. time would never get going...maybe.
How will all the black holes link up given the current inverse laws on gravity also.. Would they not necessarily be so far apart theycould never get back together... or at this point will space reverse its expansion and we see bodies growing closer in much the same manner as we now see bodies growing apart via expansion.
Interesting propositions raised for me I must say.
As the black holes reduce the density of the uncleared space.. time must speed up given the elimination of matter one would think... the sums will say so.
Well if nothing else Ron you got me thinking.. thanks.
