Surely anyone on earth who has the technical ability to deflect an asteroid precisely to hit one part of the planet, would also have the technical ability to just bomb that part of the planet directly - with much lower risk of accidentally hitting the wrong part?
- perihelions 3y agoThe scale of asteroid impacts is much larger than nuclear war. An actor could take out an entire continent at once, or end human civilization globally. It's not easy, but it's something like a 3-4 order of magnitude multiplier if you figure out how to do it.
- throwaway4aday 3y agoYeah right, MAD is a deterrent not a first strike weapon. Besides that, asteroids spend most of their time extremely far from Earth. If you launched some mega project to get out there and redirect one that wasn't already headed for us it would take you years of preparation and then years of execution time. Your enemy could easily see all of this activity and decide to just start a conventional war in the mean time to take you out and still have enough time to deflect your war asteroid. It's a dumb scifi plot device not a practical weapon.
