I have entertained ideas that our universe is being ripped apart by bigger, older objects that are so old that they have gone cold and radiate nothing but gravity. Our universe could be like like an explosion in vacuum where, after the initial violence and heat, continues to expand faster to reach equilibrium due to the gravitational pull to fill a much larger reality than our observable universe. I suspect that “dark matter” is a flawed theory that will be disproved.

Gravity decreases by the square of the distance e between ... If you were correct, such ‘old objects’ would be ripping things apart at the edges, and astronomers aren’t observing that.
