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 ...
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]
[2] [4] [27] [28] Nat Schachner's 1934 short story "When the Sun Dies" describes the entire Earth freezing over in the 1980s as a result of a reduction in solar activity, [2] [6] [29] and in Arthur C. Clarke's 1949 short story "History Lesson", future Venusians find humanity extinct due to the environmental changes brought about by the Sun fading.
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 ...
Apocalyptic fiction is a subgenre of science fiction that is concerned with the end of civilization due to a potentially existential catastrophe such as nuclear warfare, pandemic, extraterrestrial attack, impact event, cybernetic revolt, technological singularity, dysgenics, supernatural phenomena, divine judgment, climate change, resource depletion or some other general disaster.
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.
