|Universe on edge of collapse, at least on cosmological time scale |
By Stephen Morgan Mar 26, 2015 in Science
Astronomers believe the universe is on the edge of "imminent" detruction, at least when viewed on a cosmological time scale.
According to some scientists, we are far closer to a "cosmological collapse" than we think. They now believe that the so-called "Big Crunch" will start far earlier than previously thought, leading to the destruction of all matter and the end of time. From the point of view of science, this collapse is "imminent," but, sleep peacefully, for us that means a few tens of billions of years.
Physicists Nemanja Kaloper at the University of California, and Antonio Padilla at the University of Nottingham have published a paper in Physical Review Letters, which proposes a new model of cosmological collapse and its implications.
Their ideas are based on the theory that the Big Bang will be followed by a "Big Crunch," when the universe will collapse in on itself destroying everything in existence. The increase in the mass of matter in the universe will eventually cause gravity to become so powerful that it sucks the universe down into a centripetal spiral of self-destruction.
Matter in the form of planets, suns, cosmic dust, comets and asteroids will begin to clump together and galaxies and universes will fuse. In the end the universe as we know it will degenerate into a massive black hole or singularity and could also explode again into another Big Bang.
