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.
Gray goo (also spelled as grey goo) is a hypothetical global catastrophic scenario involving molecular nanotechnology in which out-of-control self-replicating machines consume all biomass (and perhaps also everything else) on Earth while building many more of themselves, [1] [2] a scenario that has been called ecophagy (the literal consumption of the ecosystem). [3]
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 ".
A cobalt bomb is a type of "salted bomb": a nuclear weapon designed to produce enhanced amounts of radioactive fallout, intended to contaminate a large area with radioactive material, potentially for the purpose of radiological warfare, mutual assured destruction or as doomsday devices. There is no firm evidence that such a device has ever been ...
A pandemic [162] involving one or more viruses, prions, or antibiotic-resistant bacteria. Epidemic diseases that have killed millions of people include smallpox, bubonic plague, influenza, HIV/AIDS, COVID-19, cocoliztli, typhus, and cholera.

In the ‘Unfinished Fable of the Sparrows’, a group of small birds come up with a plan to capture an owl egg and raise the chick as their servant.
A Miami Herald investigation into the boat crash that killed a 17-year-old Lourdes student reveals a deeply flawed probe as FWC investigators and prosecutors built a case against George Pino.
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...
