The argument was about whether or not we could detect asteroids that could destroy earth. I quoted NDT and you basically said he was full of shit and you know better. I said it would take a long time (years) for an asteroid to reach us, and you brought up the 'Russian meteorite' incident as proof that we couldn't see a 10-15km asteroid approaching us within our reaction time (it took 12 years for Voyager 2 to go from earth to Neptune). I brought up that multiple organizations are scanning for that EXACT thing, e.g. NEO's.
We can detect things that are large enough to kill us in time to do something about them. Your opinion doesn't matter on the subject, it's a fucking fact.
Now you say I've changed the subject, and that I 'fail'. lol How so?
