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]

Artist's concept of the Earth 5–7.5 billion years from now, when the Sun has become a red giant While the future cannot be predicted with certainty ...
The heat death of the universe (also known as the Big Chill or Big Freeze) [1] [2] is a hypothesis on the ultimate fate of the universe, which suggests the universe will evolve to a state of no thermodynamic free energy, and will therefore be unable to sustain processes that increase entropy.
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.
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.
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 ...
The book also illustrates Earth's eventual fate by compressing its full 12 billion-year history into 12 hours on a clock, with the first life appearing at 1:00 am, the first animals and plants appearing at 4:00 am, and the present day being 4:29.59 am. The Earth is destroyed by the Sun at "high noon", though animals and plants come to an end by ...
