Hole in Asteroid Belt Reveals Extinction Asteroid

eldavojohn writes "Further evidence for the asteroid mass extinction theory has been discovered as a break in the main asteroid belt of our solar system. From the article, "A joint U.S.-Czech team from Southwest Research Institute (SwRI) and Charles University in Prague suggests that the parent object of asteroid (298) Baptistina disrupted when it was hit by another large asteroid, creating numerous large fragments that would later create the Chicxulub crater on the Yucatan Peninsula as well as the prominent Tycho crater found on the Moon.""

Re:Gap in asteroid tracking data -- Earth at risk?

The idea is that these collisions increase the number of asteroids that cross our orbit and can therefore have a chance of hitting us. It takes a while though. We don't really care about something that might hit us 160 million years from now. We care about something that might hit us say, this century. So we look at the ones that are already whizzing around in our neighborhood.
