>When I read about what people have to do to earn money in the field of physics, it makes me glad that so many of them are unemployed.
Yeah okay, physicists never got poor by chasing DoD funding, you're right. Bunker-penetrating warheads - always handy! And yeah, many scientists and engineers could be put to work improving the lot of humanity instead of making better weapons. But hey, there's overlap: Sooner or later our planet will be struck by a meteorite that will cause serious damage to our species.
It will be quite nice to know a couple of days in advance roughly how fucked we will be when it hits.
