My own theory without any scientific knowledge of such things is that the multiverse theory is true but different than imagined today. Imagine a cluster of balloons or grapes would be more appropriate, touching each other and having a common orifice (black/white hole)... Our biggest puzzle right now is the cosmic expansion at an accelerated rate. Well, as one balloon deflates, the other inflates exchanging all matter that has been "recycled" through the black hole... The force that is acting and regulating the cosmic inflation/deflation probably has to do with entropy or "cosmic osmosis".
If anyone asks how I know this... it came to me in my sleep during an afternoon nap.
