My theory on black holes, white holes, worm holes, and the Universe...?

Your white hole theory is actually similar to the M theory that is very popular right now. Have you considered that the big bang is actually a "white hole" as you call it? In M theory our Universe is a little bubble that formed after 2 membranes collided and caused a breach in the multiverse, and thereby a "big bang." The largest bang, besides the big bang, is actually a hypernova, otherwise called a gamma ray burst. A supernova actually forms a neutron star, not a black hole. It takes a hypernova to form a black hole. A hypernova occurs when 2 neutron stars collide, or from the death of a wolf-rayet type of star which is a super-mive and very volatile type of star which lives a short time until it goes "hypernova" and dies with a gamma ray burst and forms a black hole.
