Physicists have proposed a mechanism for "cosmological collapse" that predicts that the universe will soon stop expanding and collapse in on itself, obliterating all matter as we know it. Their calculations suggest that the collapse is "imminent"—on the order of a few tens of billions of years or so—which may not keep most people up at night, but for the physicists it's still much too soon.

In a paper published in Physical Review Letters, physicists Nemanja Kaloper at the University of California, Davis; and Antonio Padilla at the University of Nottingham have proposed the cosmological mechanism and analyzed its implications, which include an explanation of dark energy.

"The fact that we are seeing dark energy now could be taken as an indication of impending doom, and we are trying to look at the data to put some figures on the end date," Padilla told Phys.org. "Early indications suggest the collapse will kick in in a few tens of billions of years, but we have yet to properly verify this."

Whew!  For a second there, I thought it read in a few tens of millions of years. ;-) To read more, click here.
