Early Earth May Have Rotated MUCH Faster

Before the mega-collision that scientist believe created the moon, Earth may have rotated on its axis once every four hours. (New Scientist)

Imagine that. Two hours of daylight. Two hours of stars. Pretty amazing. How different would life on Earth be? Would there be life at all? Could intelligent life have developed with short, frequent sleep patterns? Would sleeping have anything to do with night and day?

According to New Scientist, an object the size of Mars collided with the Earth about 4.5 billion years ago. The impact would have delivered enough force to significantly slow the Earth's early rotation, perhaps reversing it. The collision also would have created a cloud of debris that eventually formed the moon.

About Me

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
