Big Rip
(astronomy) A hypothetical end of the universe in which its rate of expansion becomes infinite in finite time, resulting in all matter being torn apart.
The rate of this expansion may eventually tear the Universe apart, forcing it to end in a Big Rip; alternatively dark energy may decay, reversing the Big Bang and ending the Universe in a Big Crunch; or the Universe may simply expand forever. Source: Internet
