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.
The universe should thus achieve, or asymptotically tend to, thermodynamic equilibrium, which corresponds to a state where no thermodynamic free energy is left, and therefore no further work is possible: this is the heat death of the universe, as predicted by Lord Kelvin in 1852.
This future history and the timeline below assume the continued expansion of the universe. If space in the universe begins to contract, subsequent events in the timeline may not occur because the Big Crunch, the collapse of the universe into a hot, dense state similar to that after the Big Bang, will prevail.

Far in the future, past the death of the Sun and the annihilation of the Earth, everything will simply evaporate.
A quatrain by Nostradamus that stated the "King of Terror" would come from the sky in "1999 and seven months" was frequently interpreted as a prediction of doomsday in July 1999. [151] 18 Aug 1999 The Amazing Criswell: The predicted date of the end of the world, according to this psychic well known for predictions. [152] 11 Sep 1999 Philip Berg
The universe could then consist of an infinite sequence of finite universes, with each finite universe ending with a Big Crunch that is also the Big Bang of the next universe. A problem with the cyclic universe is that it does not reconcile with the second law of thermodynamics , as entropy would build up from oscillation to oscillation and ...
Rudolf Virchow Medical Society is based in New York, and offers Rudolf Virchow Medal. [139] Hospital – Campus Virchow Klinikum, Cardiology Center. Campus Virchow Klinikum (CVK) is the name of a campus of Charité hospital in Berlin. The Rudolf Virchow Monument, a muscular limestone statue, was erected in 1910 at Karlplatz in Berlin. [140]
In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until distances between particles will infinitely increase.
