Universe may be on the brink of collapse (on the cosmological timescale)

(Phys.org)--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.
