An object (depending on consistency) of about 100m is enough to wipe out a city and do enough damage to the environment. Something of 8-20km is in the same category as what wiped out the dinosaurs (10-15km).
So the first solution seems like an obvious brute-force approach that definitely does not require any fancy graph theory. I have thought of this but never used it because it seems so tedious and like it defeats the point of the game.
Thank you. They act as if the “best minds” need not read or reason beyond logic and math. Having a “best mind” requires a lifelong dedication to understanding other people, ideas, and history above all else.
