Dinosaur Extinction May Predict Future
Science has now accepted the fact that the dinosaurs were killed 65 million years ago due to an impact from outer space. Could that type of extinction be in our future? Understanding what caused this impact could help to answer that question.
A new computer simulation shows that the ultimate cause was the fact that Mercury?s orbit wobbled during that period. This could have pushed an asteroid towards our planet, wiping out most of the living things on it.
?Our best calculations show that the dynamical state of the Solar System changed abruptly about 65 million years ago,? says Bruce Runnegar of the UCLA Center for Astrobiology.
