What is the origin of the universe？
I believe in reproduction of the universe---- as in the birth and death of star's, planet's and black holes. Death.... for celestial body's comes in many forms.
Dark matter.... is the mysterious substance that probably bonds everything else in the cosmos. I believe, that the birth of our universe----came from a massive black hole explosion, where 99.99% of antimatter in the universe was spent during the explosion; that will continue to expand forever and forever.
