I would like to start be saying I'm no Physicist.
Anyway, my question is: Could black holes be driving the expanding universe (dark energy)?
When I think of the image that the effect of massive objects have on space/time (gravity) and the so-called curvature it creates, it makes sense to me as far as moons, planets, stars etc.
But what interests me is, what is the extent that a black hole has on space/time curvature?
Rather than stretching space/time down into a well, could the stretching be happening in reverse so to speak? Is it mathematically possible to estimate all the black holes and their sizes and to account for this much stretching/energy?
Okay, I see where my wording has gone wrong to the question I was initially trying to ask. The question was not about the 'curvature' of space/time but rather the 'creating' of space/time with black holes. Kind of like space/time fabric creating/expanding machines. The systems that gravitate towards each other, such as the Milky Way and Andromeda would not seem to be affected or stretched apart due to gravitational forces but everything outside of these gravitational forces would expand away.
Take a sun for instance, it has a finite impact on the curvature of space/time fabric, but take that same sun and make it a black hole and the impact on the curvature of space/time seems different to me at or in the event horizon. Infinite stretching so to speak. With the results of the fabric expanding outward in all directions.
