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]
A 0.05 Gy dose will increase death due to cancer 10 fold, from the normal 0.5 per 1000 birth rate to a rate of 5 per 1,000. [ citation needed ] An antenatal dose of 1 Gy in the first trimester causes the lifetime risk of fatal cancer sometime in the child's life to increase from c. 25% in non-exposed humans to 100% in the first trimester after ...
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.

Skin cancer may occur following ionizing radiation exposure following a latent period averaging 20 to 40 years. [41] [42] A chronic radiation keratosis is a precancerous keratotic skin lesion that may arise on the skin many years after exposure to ionizing radiation.
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.
Magnetic hyperthermia is an experimental treatment for cancer, based on the fact that magnetic nanoparticles can transform electromagnetic energy from an external high-frequency field to heat. [21] This is due to the magnetic hysteresis of the material when it is subjected to an alternating magnetic field. [ 22 ]
When extreme temperature elevation occurs, it becomes a medical emergency requiring immediate treatment to prevent disability or death. [citation needed] Almost half a million deaths are recorded every year from hyperthermia. [citation needed] The most common causes include heat stroke and adverse reactions to drugs.
