Did White holes create galaxies?

​Are there many universes? Is at the other end of a black hole deflating a universe a white hole inflating another universe? Each galaxy in our universe was created by a white hole spewing out spacetime matter and energy from another universe. Now those white holes have become black holes which are spewing this matter and energy back into another reality/ dimension/ universe.
What is gravity? Perhaps spacetime is exiting our reality into another dimension/ universe through the center of the Earth trying to pull us down with it :) ?
And, yes, I have been known to make people's brains hurt!
