Comments in here take me back to the membrane theory. This theory....to me....offers an explanation of how the universe can start from a single point and have inflation... If you have 2 sheets of paper representing the seperate universes and you touch them flat against each other then you get a single point of contact along the entire sheets of paper. That makes the beginning of the universe a single point but the bang occurs along the entire plane, making it appear to be....inflation? Who knows, maybe our universe is over 300 b light years along the plane but only a 15-90 b from top to bottom....
