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 for the end of planet Earth.
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.
Additional safety arguments beyond those based on Hawking radiation were given in the paper, [25] [26] which showed that in hypothetical scenarios with stable micro black holes massive enough to destroy Earth, such black holes would have been produced by cosmic rays and would have likely already destroyed astronomical objects such as planets ...
Here are 10 weird things that can kill you almost instantly. ... However, if one measuring 50-meters-wide and speeding towards Earth at roughly 9 miles per second exploded in the air, it would be ...
The Doomsday clock was set at 89 seconds to midnight on Tuesday morning, putting it the closest the world has ever been to what scientists deem "global catastrophe."
Earth and the Moon will be most likely be destroyed by falling into the Sun, just before the Sun reaches the largest of its red giant phase when it will be 256 times larger than it is now. Before the final collision, the Moon possibly spirals below Earth's Roche limit, breaking into a ring of debris, most of which falls to Earth's surface. [216 ...
In Chodenji Machine Voltes V, a Magmite bomb was planted by general Oslack to destroy the Earth. In the cartoon Invader Zim, the Planet Jackers tried to feed the Earth to their sun to keep it from going out. In Gunbuster, Buster Machine #7 and #19 work in tandem to destroy an Earth-sized life form and a black hole which it carries in tow.
Asteroid 2024 YR4 has a 1.3% chance of impacting Earth in 2032, NASA reports. Astronomers all over the world are watching the asteroid, trying to narrow down its future path.
