We are in a black hole inside out ! What holds the space from collapsing in from gravity is dark matter expanding "space" dark energy is the gravity against it. there will be 3 things that can occur in the end !
#1 The universe keeps expanding and stars and galaxies drift further apart until all the stars burn out and there is total darkness and cold.
#2 Dark matter "space" will sling shot back at some point and we will die in a crack or splat
#3 The universe will keep expanding and growing in velocity until the fabric of space will be ripped and in a blink we will all die in an explosion of energy like the beginning of this universe began , Thank You for reading.
Consider a black hole as being the portal between two universes. On the one side it is sucking matter in (death of an old universe) and on the other it is spewing it out (big bang, start of new one).
When a universe is created it expands like a balloon (as matter from elsewhere is pumped into it) until enough black holes have formed and it starts draining energy and shrivelling up.
I think of it as a multi dimensional lava lamp. Are there any obvious faults with my idea?
