    Interesting item in the latest New Scientist.

    The great British mathematician, Roger Penrose, playing with the maths of cosmology, came up with ...

    "According to the standard view, dark energy will lead the universe into an eternal accelerating expansion. Every bit of matter will eventually lose contact with every other bit. "It all just seemed unbelievably boring to me," Penrose says.

    Then he found something interesting within it: at the very end of the universe, the only remaining particles will be massless. That means everything that exists will travel at the speed of light, making the flow of time meaningless. After a few mathematical manipulations of infinity, out popped a never-ending universe, where new big bangs are the inevitable result of a universe's demise. In Penrose's theory, one cosmos leads to another. "I used to call it a crazy scheme, but I'm starting to believe it now," he says."

    So the end of the universe may lead to new universes being created via new Big Bang events. Anyone care to comment?
