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 ...
The 1st-century bishop of Edessa predicted this date to be the birth date of the Antichrist and the end of the universe.

In the 1970s, the future of an expanding universe was studied by the astrophysicist Jamal Islam [12] and the physicist Freeman Dyson. [13] Then, in their 1999 book The Five Ages of the Universe, the astrophysicists Fred Adams and Gregory Laughlin divided the past and future history of an expanding universe into five eras.
[1] [2] [3] Nonetheless, some physicists have proposed that a "Big Crunch-style" event could result from a dark energy fluctuation. [4] The hypothesis dates back to 1922, with Russian physicist Alexander Friedmann creating a set of equations showing that the end of the universe depends on its density. It could either expand or contract rather ...
22.3 billion The estimated time until the end of the universe in a Big Rip, assuming a model of dark energy with w = −1.5. [122] [123] If the density of dark energy is less than −1, then the universe's expansion will continue to accelerate and the observable universe will grow ever sparser.
The book guides readers through the history of the research into these concepts, including the work on the Laser Interferometer Gravitational-Wave Observatory, or LIGO, that led to the 2017 Nobel.
The cosmic web — ribbons of gas and dust tying galaxies together — are the largest structures in the Universe, and a new study shows they are growing hotter over time.. Utilizing a phenomenon ...
