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.

According to the Century 10, Quatrain 74 of The Prophecies (1555), [200] the "start" of the end of the world begins in the given date of 3797, with a prolonged global war lasting between 25 and 29 years, followed by a series of smaller wars, [201] but most interpretations of Nostradamus dates are aware of required basic mathematic sums, given ...
On this timescale, any discrete body of matter "behaves like a liquid" and becomes a smooth sphere due to diffusion and gravity. [145] 1.16×10 67 (11.6 unvigintillion) The estimated time until a black hole of one solar mass today, will have decayed by the emission of Hawking radiation. [148] 1.54×10 91 –1.41×10 92 (15.4–141 ...
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 green, orange and yellow lines indicate how surface temperatures will likely respond if leading carbon emitters begin to reduce reliance on fossil fuels. Without immediate curbs, temperatures are set to follow the red track, and increase between 3.2 and 5.4 degrees Celsius by 2100. The green line shows how we can minimize warming if ...
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
This occurs most frequently at the implementation stage of adoption. [127] The degree to which the variation departs from the mainline version first presented to them, is a re-invention, and it can occur frequently in a variety of ways. [134] Such re-inventions can begin to diffuse separately from the original innovation. [135]
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach absolute zero, an event potentially followed by a reformation of the universe starting with another Big Bang.
