"Nobody knows what this stone is really worth."A 1.4 pound piece of stone found in Morocco may be the first known "terrestrial meteorite," which basically means a rock that made a roundtrip from Earth, into space, and back again — like a cosmic paddle ball, with gravity as the elastic string that eventually brings the rock back to Earth.
Due to certain unique features, scientists surmise that this cosmic boomerang was knocked into space about 10,000 years ago when an asteroid hit our planet with incredible speed, according to theheld earlier this month in Lyon, France. After spending anywhere from 2,000 to tens of thousands of years in space, the theory goes, it eventually plunged back to our planet.
The research team is busy confirming if their hypothesis behind the rock's origin is correct through various testing techniques, according to the presentation abstract. But other scientists not involved in the study say it's too soon to say for sure, and expressed caution over making an extraordinary claim.
"I think there is no doubt that this is a meteorite. It is just a matter of debate if it is really from Earth," said Frank Brenker, a geology professor at Germany's Goethe University in Frankfurt,
