Were The The Dinosaurs Killed Off By A Giant Molecular Cloud ?
New research suggests that dinosaurs and their subsequent apocalypse was caused by a sudden “global cooling” which occurred when Earth passed through a “giant molecular cloud”. GeoBeats news reports: An asteroid is commonly believed to be responsible for the mass extinction that wiped out the dinosaurs around 65 million years ago, but a new study points out another possible cause. A team of researchers argues that the Earth’s prolonged collision with a dense, dark cloud provides a better explanation for the catastrophic event.
