The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth 's surface, the cooling rate of the planet's interior, the gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
Artist's concept of the Earth5–7.5 billion years from now, when the Sunhas become a red giant. While the future cannot be predicted with certainty, present understanding in various scientific fields allows for the prediction of some far-future events, if only in the broadest outline. [1][2][3][4]These fields include astrophysics, which ...
The world was to be destroyed by terrible flooding on this date, claimed this leader of a UFO cult called Brotherhood of the Seven Rays. The fallout of the group after the prediction failed was the basis for the 1956 book When Prophecy Fails. 22 Apr 1959 Florence Houteff
Doomsday device. 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 ...
The ultimate fate of the universe is a topic in physical cosmology, whose theoretical restrictions allow possible scenarios for the evolution and ultimate fate of the universe to be described and evaluated. Based on available observational evidence, deciding the fate and evolution of the universe has become a valid cosmological question, being ...
Artist's impression of a major asteroid impact. An asteroid caused the extinction of the non-avian dinosaurs. [1] 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]
Nuclear holocaust. 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. Such a scenario envisages large parts of the Earth becoming uninhabitable due to ...
Bringing the Moon's orbit within the Roche limit of Earth (within about 18,000 km (11,000 mi)) would also destroy it. [3] Without the Moon, tides would still happen—the Sun's gravity also causes tides—but they would be substantially reduced, [8] a quarter of the size of the current spring tide. [9] The sudden disappearance of the Moon ...
