If Earth is not ejected during a stellar encounter, then its orbit will decay via gravitational radiation until it collides with the Sun in 10 20 (100 quintillion) years. [109] If proton decay can occur and Earth is ejected to intergalactic space, then it will last around 10 38 (100 undecillion) years before evaporating into radiation. [110]

The chronology of the universe describes the history and future of the universe according to Big Bang cosmology.. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
After the sun celebrates its 11 billionth birthday, scientists believe it will continue to expand to the point where it is 166 times bigger than it is now.
Earth and the Moon will be most likely be destroyed by falling into the Sun, just before the Sun reaches the largest of its red giant phase when it will be 256 times larger than it is now. Before the final collision, the Moon possibly spirals below Earth's Roche limit, breaking into a ring of debris, most of which falls to Earth's surface. [210 ...
A true vacuum exists so long as the universe exists in its lowest energy state, in which case the false vacuum theory is irrelevant. However, if the vacuum is not in its lowest energy state (a false vacuum), it could tunnel into a lower-energy state. [27] This is called vacuum decay.

Up until 2012, there was no way to confirm whether the possible collision was going to happen or not. [19] In 2012, researchers came to the conclusion that the collision is definite after using the Hubble Space Telescope between 2002 and 2010 to track the motion of Andromeda. [20] This results in the formation of Milkdromeda (also known as ...
