Get ready for something HUGE. Kosmogonia Launch Event - July 12th: Comment "LAUNCH" for a link to get involved
He walks through the fundamental difference between airbursts and ground impacts, using Meteor Crater as the textbook example. That kilometer-wide hole in Arizona was carved by an iron meteorite dense enough to punch straight through the atmosphere and detonate on contact. Lighter objects, by contrast, explode mid-air before they ever reach the surface. The distinction matters because the physics and the resulting damage patterns are completely different. Ground bursts leave craters, airbursts leave blast zones and thermal signatures across wide areas. Understanding which type of event occurred in the past changes how we read the geological record and what we should be looking for in the field.
