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, gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
Nuclear war is an often-predicted cause of the extinction of humankind. [1]Human extinction or omnicide is the hypothetical end of the human species, either by population decline due to extraneous natural causes, such as an asteroid impact or large-scale volcanism, or via anthropogenic destruction (self-extinction), for example by sub-replacement fertility.
Eventually, however, all multicellular life will die out. [83] The first sea animals to go extinct will be large fish, followed by small fish and then, finally, invertebrates. [80] The last animals to go extinct will be animals that do not depend on living plants, such as termites, or those near hydrothermal vents, such as worms of the genus ...
After the sun celebrates its 11 billionth birthday, scientists believe it will continue to expand to the point where it is 166 times bigger than it is now.
The SpaceX and Tesla pioneer has warned that travel to other planets was necessary as Earth would be engulfed by the Sun. Elon Musk says humans must leave Earth "because sun will engulf our planet ...
[109] [110] [111] A 1997 assessment states that over a third of Earth's land has been modified by humans, that atmospheric carbon dioxide has increased around 30 percent, that humans are the dominant source of nitrogen fixation, that humans control most of the Earth's accessible surface fresh water, and that species extinction rates may be over ...
By studying old and dead stars, we can discover what will happen to our sun in the far, far future. And it won't end with a big explosion.
Permian–Triassic extinction event: 0.2933 gal Cretaceous–Paleogene extinction event: 0.0013 gal Emergence of anatomically modern humans: Future (years from now) 0.15 gal Mean time between impacts of asteroidal bodies in the order of magnitude of the K/Pg impactor has elapsed.
