"As if you didn't have enough to worry about, the universe in recent decades was discovered to wield a mysterious pressure that issues forth from the vacuum of space and that acts opposite cosmic gravity. Not only that, this "negative gravity" will ultimately win the tug-of-war, as it forces the cosmic expansion to accelerate exponentially into the future." Neil deGrasse Tyson, from his new book Astrophysics for People in a Hurry.
