   Aug 11, 2020 · Astronomers have long contemplated the ultimate end of the cosmos.

   What if the universe reverses the Big Bang?

   • Alternatively, the Universe could 'shrink', decrease or decay, effectively reversing the Big Bang and destroying the Universe in a Big Crunch. A third theory is described as the Big Freeze. Many theoretical physicists believe the Universe will end, and it could happen at any point between 2.8 billion years and 22 billion years from now.

   What is the 'cosmic age' of the universe?

   • Cosmologists have used this theory, as well as data from studies of cosmic background radiation, to determine the 'cosmic age' of the Universe to be around 13.799 billion years old, and this can help predict how, and when, the Universe could end. Here are the three theories proposing how that end could come to be.

   How old is the universe?

   • The universe as we know it is now 14 billion years old, which seems like a long time but is only an infinitesimal sliver of the trillions and quadrillions of years of darkness to come. It will mean that everything interesting in our universe happened in a brief flash, at the very beginning. A promising start, and then an eternal abyss.
