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.
In approximately 300,000 years, WR 104, a triple star, is expected to explode in a supernova. It has been suggested that it may produce a gamma ray burst that could pose a threat to life on Earth should its poles be aligned 12° or lower towards Earth. However spectroscopic observations now strongly suggest that it is tilted at an angle of 30 ...
A computer determines that in approximately one month, enough of Element 112 will emerge from the deep earth to cause the entire planet to explode. A desperate operation ensues worldwide to blast and trench the ground to let water in and cover Element 112, keeping it from drying out and expanding.

The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
The explosion will be visible to the naked eye on Earth and enable new science. ... and inevitably, explode like a thermonuclear bomb. Neither star is destroyed however, and the process repeats ...
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach absolute zero, an event potentially followed by a reformation of the universe starting with another Big Bang.
A meteor hurtling towards earth wouldn't count, while tinkering with viruses to make them more dangerous would. From the 1950s through the 1980s the threat of nuclear war felt imminent.
