Scientists zero in on why time flows in one direction
The big bang could be a normal event in the natural evolution of the universe that will happen repeatedly over incredibly vast time scales as the universe expands, empties out and cools off, according to two University of Chicago physicists.
“We like to say that the big bang is nothing special in the history of our universe,” said Sean Carroll, an Assistant Professor in Physics at the University of Chicago. Carroll and University of Chicago graduate student Jennifer Chen will electronically publish a paper describing their ideas at http://arxiv.org/.
Carroll and Chen’s research addresses two ambitious questions: why does time flow in only one direction, and could the big bang have arisen from an energy fluctuation in empty space that conforms to the known laws of physics?
