Many hypothetical doomsday devices are based on salted hydrogen bombs creating large amounts of nuclear fallout.. A doomsday device is a hypothetical construction — usually a weapon or weapons system — which could destroy all life on a planet, particularly Earth, or destroy the planet itself, bringing "doomsday", a term used for the end of planet Earth.
Mushroom cloud from the 1954 explosion of Castle Bravo, the largest nuclear weapon detonated by the U.S.. A nuclear holocaust, also known as a nuclear apocalypse, nuclear annihilation, nuclear armageddon, or atomic holocaust, is a theoretical scenario where the mass detonation of nuclear weapons causes widespread destruction and radioactive fallout, with global consequences.
These weapons would be used to destroy hardened, underground military bunkers or other below-ground facilities. An underground explosion releases a larger fraction of its energy into the ground, compared to a surface burst or air burst explosion at or above the surface, and so can destroy an underground target using a lower explosive yield .
any weapon that is designed or intended to cause death or serious bodily injury through the release, dissemination, or impact of toxic or poisonous chemicals, or their precursors; any weapon involving a biological agent, toxin, or vector; any weapon that is designed to release radiation or radioactivity at a level dangerous to human life [54]
A global catastrophic risk or a doomsday scenario is a hypothetical event that could damage human well-being on a global scale, [2] even endangering or destroying modern civilization. [3] An event that could cause human extinction or permanently and drastically curtail humanity's existence or potential is known as an "existential risk". [4]
The regular British army could be wiped out in as little as six months if forced to fight a war on the scale of the Ukraine conflict, a defence minister has warned. Alistair Carns said a rate of ...
South Africa also manufactured several complete nuclear weapons in the 1980s, but subsequently became the first country to voluntarily destroy their domestically made weapons stocks and abandon further production (1990s). [12] [13] Nuclear weapons have been detonated on over 2,000 occasions for testing purposes and demonstrations. [14] [15]
Nick Bostrom suggested that in the pursuit of knowledge, humanity might inadvertently create a device that could destroy Earth and the Solar System. [53] Investigations in nuclear and high-energy physics could create unusual conditions with catastrophic consequences. All of these worries have so far proven unfounded.
