Its funny how some people refuse to believe the depth of our universe and how small we truly are in the scheme of things! I liked how Halle explained the world of the water flea and how it related to our own understanding of the universe..We are just trapped in a little tank called earth and we cannot understand the full functionality of the physics at work in the universe..Some get a glimpse of a higher understanding but its not enough to explain the universe we live in..A multiverse could easily explain the big bang, singularities, black holes, worm holes(possibility of), white holes(possibility of). The physics of a black hole point in the direction of a white hole being absolutely necessary...Unless somehow allllll that matter is somehow turned into x-rays and gamma rays but i find that somewhat hard to believe. To me it seems much more probable that the black hole is a ripple or connection of some sort between two dimensions or universe's...Possibly opposites..which is why we never see white holes..perhaps they are only possible in another dimensions..Or it could be governed by similar physics where high matter areas go to low mater areas...Which is exactly what our universe seems to be doing at the present time..Perhaps a black hole's contents gets trapped in between two universe's where other black holes also dump their contents until it gets to the point where it cannot hold anymore matter and creates a big bang in another universe or even our same universe...
Gravity is maybe one way to get two dimensions to touch each other..One of the most basic laws of physics, gravity, and we dont even fully understand how it works..what a bummer! perhaps the graviton...or perhaps not...superstring theory postulates the existence of the graviton, no?
