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.
Among pregnant women who are hit by lightning, the death of the fetus occurs in about half. [1] In the United States, about 1 in 10,000 people are hit by lightning during their lifetime. [1] Males are affected four times more often than females. [1] The age group most commonly affected is 20 to 45 years old. [1]
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 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.
From 1999-2023, the Journal of American Medical Association recorded 21,518 deaths where heat was either the underlying cause or the contributing cause of death, likely an underestimation, they say.
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.
“Mobile homes can really heat up because they don’t always have the best insulation and are often made of metal,” said Dana Kennedy, AARP director in Arizona, where many heat-related deaths ...
Heat-related death and throngs of visitors have Death Valley National Park officials emphasizing safety while visiting the park.
