Maybe I’m not that smart, but we’re supposed to believe that the universe was created from a thimble full of mass that exploded, but no one can tell us where the thimble full of mass come from?
Believing in one system or another may not alter the reality of our existence. It does, however, satisfy an important human need to understand our place in the universe. Without beliefs we wander aimlessly.
Though I dont understand gravity, I do believe in it. And have a great respect for it as well!
