How to Destroy the Earth


Sample –


7. Pulverized by impact with blunt instrument




  • You will need: a big heavy rock, something with a bit of a swing to it… perhaps Mars



  • Method: Criminal, really, that this blindingly obvious method was overlooked for so long. Essentially, anything can be destroyed if you hit it hard enough. ANYTHING. The concept is simple: find a really, really big asteroid or planet, accelerate it up to some dazzling speed, and smash it into Earth, preferably head-on but whatever you can manage. The result: an absolutely spectacular collision, resulting hopefully in Earth (and, most likely, our “cue ball” too) being pulverized out of existence – smashed into any number of large pieces which if the collision is hard enough should have enough energy to overcome their mutual gravity and drift away forever, never to coagulate back into a planet again.

    Well that will not do it always. For instance black holes will simply laugh about your projectile and simply absorb it with no spectacular explosion at all. But what is really interesting if the black hole starts to move after it was hit by your projectile. Impulse conservation should hold so it should start to move a bit after it was hit. But it could also be that at this singularity in space-time other laws are valid. I really would like a black hole in a lab and try to break it 😉
