The Asteroid Didn't Kill the Dinosaurs. The Dust Did.

Sixty-six million years ago, on an ordinary afternoon, a rock the size of a mountain was four minutes away from ending the world. Not one single creature on this planet looked up. This is what actually happened. Minute by minute, from four minutes out to sixty-six million years later. The bang is not the part that killed them.

Where scientists genuinely disagree, such as the Tanis site in North Dakota and how far the thermal pulse reached, the video says so out loud instead of picking the more dramatic option.
