This is awesome! (in a "possible doom for all mankind" kind of way):
Time is running out - literally, says scientist
Scientists have come up with the radical suggestion that the universe's end may come not with a bang but a standstill - that time could be literally running out and could, one day, stop altogether.
The idea that time itself could cease to be in billions of years - and everything will grind to a halt - has been set out by Professor José Senovilla, Marc Mars and Raül Vera of the University of the Basque Country, Bilbao, and University of Salamanca, Spain.
The motivation for this radical end to time itself is to provide an alternative explanation for "dark energy" - the mysterious antigravitational force that has been suggested to explain a cosmic phenomenon that has baffled scientists.

The team's proposal, which will be published in the journal Physical Review D, does away altogether with dark energy. Instead, Prof Senovilla says, the appearance of acceleration is caused by time itself gradually slowing down, like a clock that needs winding.

In some number of billions of years, time would cease to be time altogether - and everything will stop.
"Then everything will be frozen, like a snapshot of one instant, forever," Prof Senovilla tells New Scientist magazine. "Our planet will be long gone by then."
However, he adds that the team is only assuming there is one dimension of time. Itzhak Bars of the University of Southern California in Los Angeles has put forward the bizarre suggestion that there are two dimensions of time, not the one that we are all familiar with.
Prof Senovilla says: "One thing that is definitely not included in our models is the possibility of having more than one time dimension."
