Using high-pow­ered bal­lis­tics exper­i­ments, fan­cy com­put­er algo­rithms, and good old-fash­ioned ancient geol­o­gy, sci­en­tists have woven togeth­er a the­o­ry about the extinc­tion of the dinosaurs that is so pre­cise, so hot, so instan­ta­neous, as to seem unimag­in­able. Today, we bring you this sto­ry, first pub­lished on Radi­o­lab in 2013, plus an update: a spot on plan­et Earth, new­ly dis­cov­ered, that — if it holds true — has the poten­tial to tell us about the first three hours after the dinos died.
