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.
An uncertain factor is the influence of human technology such as climate engineering, [2] which could cause significant changes to the planet. [3] [4] For example, the current Holocene extinction [5] is being caused by technology, [6] and the effects may last for up to five million years. [7]
All past predictions of human extinction have proven to be false. To some, this makes future warnings seem less credible. Nick Bostrom argues that the absence of human extinction in the past is weak evidence that there will be no human extinction in the future, due to survivor bias and other anthropic effects. [34]
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 ...
A survey of AI experts estimated that the chance of human-level machine learning having an "extremely bad (e.g., human extinction)" long-term effect on humanity is 5%. [18] A 2008 survey by the Future of Humanity Institute estimated a 5% probability of extinction by super-intelligence by 2100. [19]
When our sun dies about 5 billion years from now it might look something like this glowing celestial display which was captured from 4,600 light-years away. Hubble image of a star exploding may ...
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 ...
