Recently I finished a 1977 apocalyptic sci-fi novel called Lucifer's Hammer by Larry Niven and Jerry Pournelle, which was nominated for the Hugo Award for Best Novel in 1978. This was one of the best end-of-world asteroid impact books I have ever read. I highly recommend it to anyone interested in science fiction or apocalypse stories.
As can be imagined, not since the halcyon days of cinema classics such as Deep Impact and Armageddon (joking of course, those movies are terrible), I have been thinking about comets and asteroids quite a bit lately, and the fact that if the improbable ever happens, we are all truly in deep trouble, and nothing is going to save us.
The following visualization, from the asteroid tracking foundation B612, shows 26 asteroid impacts on the earth over the past 13 years, with explosions ranging from 1 kiloton to 600 kilotons.
“To put this data in perspective, the atomic bomb that destroyed Hiroshima in 1945 exploded with an energy impact of 15 kilotons,” the organization explained in regards to the visualization. “While most of these asteroids exploded too high in the atmosphere to do serious damage on the ground, the evidence is important in estimating the frequency of a potential ‘city-killer-size’ asteroid.”
So, for all your survivalists out there, look to the skys, not to other countries on earth, for the end is nigh, and no bomb-shelter on Earth will protect you from it's fury and judgement.
