The Swan Song of the Universe

What if, taking Steven Hawking's elevation of the notion that there are subatomic particles that blip into and out of existence and combining it with the idea that the increasing expansion of the universe will some day reach a point where the atoms of the universe will no longer be able to hold together, and the idea that at the moment when the Big Bang occurred all the bulk and scope of the universe was compressed into an atom-sized space (you see where I'm going), what if every atom of the universe at the end spawned another universe? What a swan song that would be.
