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.
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 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; Timeline of the far future – Scientific projections regarding the far future
Record-setting heat waves have gripped the U.S. only weeks into summer, and at least 38 people are suspected to have died from heat-related issues so far this summer.
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.
Meth use by itself can cause heat stroke and death even when used at room temperature. The drug wreaks havoc with the body’s heat-regulation systems and spurs motion that generates internal heat.
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
