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.
According to Robert G. Mayer, author of the seminal "Embalming: History, Theory and Practice", postmortem caloricity is a "rise in temperature after death due to continued cellular oxidation." In mortuary science, there are two phases of death—somatic and cellular. Somatic death is the cessation of the tripod of life, meaning the failure of ...
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]
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.
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.

This pathology occurs due to the normal physiological drop in maternal clotting factors after delivery which greatly increases the risk of secondary postpartum hemorrhage. [14] Another bleeding risk factor is thrombocytopenia, or decreased platelet levels, which is the most common hematological change associated with pregnancy induced hypertension.
An arrhythmia is an irregular heartbeat that occurs due to a problem with the electrical activity of your heart. Types of arrhythmia include: Tachycardia. A faster-than-normal heart rate. Bradycardia.
