I'm a complete and utter layman here, so please forgive any misunderstandings, but I'm just curious about something and wonder if people could say some words on the subject. So as we understand it, the universe is constantly expanding, but expanding at an accelerated rate, so wouldn't this have some effect on the way in which bodies of matter can gravitate towards each other later in the universes life? If we take that into consideration, wouldn't it then become more difficult for black holes to form later in the universes life since the expansion of space is pulling matter further and further apart and thus consequentially weakening those gravitational interactions? Wouldn't that then imply that it would be impossible for all particles of matter to be eliminated due to black hole radiation since the gravitational forces between residual particles would be so weak that black holes simply couldn't be formed? If we took a relativistic view, couldn't we then say that the distribution of space in the universe is in fact static and that gravity is simply getting weaker as a force over time? I know observations tell us that the expansion of the universe is accelerating, and gravitational forces seem to remain constant (G), but if we considered that gravity as a force was weakening over time, wouldn't that then prevent Einstein's model of a static universe from collapsing and allow it to remain static? A lot to ask, a lot to take in, and probably a lot of educational mistakes, but the thought just crossed my mind and was tempted to ask. I'd like to further my layman's knowledge and perhaps understand it a little better, and just gain a little enlightenment. Thanks for your time.
