Naked Science: No one knows where the asteroid came from that hit the Earth 65 million years ago and wiped out the dinosaurs. They aren't even sure how it wiped out the species. New evidence suggests that dinosaurs' days were already numbered some 100 million years before the catastrophic collision. Scientists tell how it happened and predict what would happen if another 8-mile-wide asteroid were to hit our planet today.
