This is a timeline of the Universe from the Big Bang to the heat death scenario. The different eras of the universe are shown. The heat death will occur in around 1.7×10 106 years, if protons decay. [citation needed]
The idea of heat death stems from the second law of thermodynamics, of which one version states that entropy tends to increase in an isolated system.From this, the hypothesis implies that if the universe lasts for a sufficient time, it will asymptotically approach a state where all energy is evenly distributed.
This timeline uses the more intuitive linear time, for comparison with this article. The Last Question – A short story by Isaac Asimov which considers the inevitable outcome of heat death in the universe and how it may be reversed. Heat death of the universe – Possible fate of the universe
Graphical timeline of the universe. Timeline uses linear time. Heat death of the universe; List of other end scenarios than Heat Death; 1 E19 s and more; Second law of thermodynamics; Ultimate fate of the Universe; The Last Question, story by Isaac Asimov which considers the oncome of heat death in the universe and how it may be reversed.
The heat death scenario is compatible with any of the three spatial models, but it requires that the universe reaches an eventual temperature minimum. [24] Without dark energy, it could occur only under a flat or hyperbolic geometry. With a positive cosmological constant, it could also occur in a closed universe.
On Wednesday, there were 21 heat-related deaths at Beni Mellal’s main hospital as temperatures spiked to 48.3 degrees (118.9 degrees Fahrenheit) in the region of 575,000 people, most lacking air ...
Here's the timeline We then compared deaths in each county over the week following a day with accurate forecasts to deaths in the same county over the week following a day with inaccurate ...
Heat Death As expansion continues, the universe becomes larger, colder, and more dilute; in time, all structures eventually decompose to subatomic particles and photons. In the case of indefinitely continuing cosmic expansion, the energy density in the universe will decrease until, after an estimated time of 10 1000 years, it reaches ...
