Some weeks ago I asked the question about asteroid impacts. Somehow I couldnt really accept that several small impacts was worse than one big – not without proof.
And somehow my original Texas-example was probably correct – that just kills everything, and its hard to be worse than that. But if you take it down from my example of a “Texas”-asteroid to something smaller (that actually didnt completly break the litosphere/mantle and so on like Texas most likely would), and then comparing that to when it was broken in to several pieces – math prevailed over gut feelings. Then several small pieces clearly are worse than one big.
I however didnt do the math – this guy did. Very cool. (Original in Swedish – In English with google translate here. (Yes I know – google translate sucks, but its better than nothing). Much appreciated Martin!
