  1. 2:40 Shouldn’t that be “explosion hypocentre”? “Epicentre” is a term from seismology, where the energy-release event happens underground; here it happens high above ground.

  2. This is why the Earth’s surface is not covered with craters, the same way the Moon’s is. They’re in similar orbits, they would have been hit (and are still being hit) with similar densities of random objects. Erosion/deposition on the Earth tends to wipe out the traces in (geologically) short order.
