the part about amateur astronomers driving days into the australian outback just to catch a few milliseconds of starlight is kind of insane when you think about it. science is weird in the best way also didnt realise the debris itself played such a big role, i assumed it was just the impact doing all the work. makes you wonder how accurate you'd need to be if you were actually trying to deflect something heading toward earth, like the margin for error must be incredibly small
