Even if it broke up in the air, there must have been humungous chunks of the thing lying around, but the expeditions found only horizontal trees. And I have always wondered about Meteor Crater in Arizona; I never understood why a little digging did not expose a big chunk of extraterrestrial rock at the centre of the crater; but there is nothing. Any sinkholes in the Tunguska area? Well, they probably never thought to look. And why are craters made by these meteors and asteroids always round? Shouldn't the rocks come in at an angle, on average, and make an oval-shaped crater? Or is it due to the immense densities of the baryonic matter, or whatever it is, that causes them to do a fast curve and zoom right for the black hole at the centre of the earth? Cripes, every time I hit a pothole these days I wonder if some dark matter hasn't shat all over the street.
