Overview

A Discovery Channel computer simulation of a large asteroid impact on Earth, showing the scale of the devastation. It sits in a broader context of early Earth impacts and the moon-forming collision.

>the energy required to kick up a rock to a trajectory where it will hit Mars (or vice versa) is orders of magnitude more than the energy required to vaporize all nearby life, so we've got a pretty big problem already Not necessarily. Something like the asteroid that killed the dinosaurs would have created temperatures at the impact point high enough to vapourize everything but probably also chucked a lot of more distant stuff into the sky that didn't get as hot. Here's a Discovery channel 'simulation' of a large impact chucking stuff up [VIDEO] Not sure it's very accurate but it gives an impression of the sort of thing that may have happened.

Not to spoil your lunch or anything: [VIDEO] Of course 500 Km is a big difference with 400 meters but to those near the point of impact it wouldn't matter and the global effects would still be beyond anything in our history. This is one interpretation of what this could look like: [LINK]

Absolutely. I'll milk that impact for all it's worth. Too bad I'll be too busy evaporating myself to cash in on it but for a very short while I'll be the richest man on Earth ;) And I'll re-invest my riches into start-ups that aim to deal with very fast climate change. [VIDEO] Applications are open.
