Have you grasped nothing of the reason why I am in the world?


In 1908, an asteroid measuring perhaps 90-190 meters across struck Siberia, damaging over 2,000 square kilometers of Russian forest – an area that measures larger than New York’s five boroughs. Scientists estimate that the energy of that explosion was about 1,000 times that of the atomic bomb the U.S. dropped on Hiroshima in 1945.

This is far from the only close call that humans have had with asteroids. In 2004, an asteroid big enough to have its own small moon narrowly missed the planet. In 2013, an asteroid struck the Russia countryside with many times the force of the Hiroshima bomb, and was widely captured on video.

And of course, it was an asteroid, smashing into the Earth with the force of more than billion Hiroshima bombs, which nixed the dinosaurs and allowed humans to take over the Earth in the first place. [Previously: The event appears to have hit all continents at the same time | more] […]

The probability that you’ll die from an asteroid may be surprisingly large – about the same probability as dying from a plane crash, according to research.
