Meteor Impact in Slow Motion Duke University Research

This sequence of high-speed videos reveals what happens underground when a missile or meteor hits the earth. Shown first at slow, then at medium and finally at high impact speeds, each video stretches a split-second impact to more than six seconds of playback time. The study explains why soil and sand get stronger when they are struck harder. Video courtesy of Abram Clark. Read more: Website: YouTube: Google : http://plus.
