The article explains a ridiculous theory, that's actually not very new. First, a little background knowledge on Black Holes, they're infinitely dense, small, and hot, and vacuum up everything near it. Supposedly Black Holes instantly eliminate out of existence all the matter it sucks in, and is so dense it does not emit light. But this theory says that there is actually another doorway in every Black Hole, the other side is called the White Hole, and all the matter it sucks in ends up on that other side. So that other side would be an entire parallel, alternate universe. Then that matter slowly forms back into planets and stars again. So the big idea is that our universe is infinitely sinking back down the drain - all the Black Holes - and fills up into another universe, a constant fluctuation between two universes.
This theory is extremely far out and is not taken very seriously or importantly by most major atronomers in the world. it completely breaks far away from many very old, concrete laws and logic in astronomy. The article explains the testable flaws and the proababilities and possibilities. Personally I can't ever even grasp the concept of the epic known universe so I can't understand why this theory could be possible or impossible, but I think it's a frigging cool idea.
