Well thank you all for the responses. It definitely clarifies some concepts for me, and of course only begs more questions.
Phi - I can definitely see how some models would reflect that. Especially thinking of an earlier universe, where photons, gluons, and potential other unstable mass-less particles would be the only thing in existence in that period of time. In the concept of another potential universe, that would mean it most likely started with less energy that would suffer from a heat death scenario at a much younger age, without the ability for clusters of mass to form black holes right?
Strange - Your answer really made me think of think of space-time in a purely boundless and existential manner. It demanded more clarity for me, and I did some looking into cosmic radiation and the particle horizon concepts and I think those helped me be able to visualize more along the lines of what has/is more likely happened/happening, which leads into AJB's post.
AJB - I definitely see how this can make my hypothesis way less probable. If black holes are creating space-time in between galaxies it would be far less probably to see galaxies colliding, unless on a faster trajectory towards each other faster than the space-time is being created in between the two.
Which leads me to think, it is simply our perspective of distance and the expansion of the universe, but it also only makes me want to look into alternative relationships black holes may have with dark matter / dark energy and space-time. The explanations and answers you guys gave have led me down a road to more insight, so thank you for that. Definitely have some reading to do
