Harvard professor Avi Loeb believes he may have found fragments of alien technology from a meteor that landed in the waters off of Papua New Guinea in 2014.

Loeb and his team just brought the materials back to Harvard for analysis. The U.S. Space Command can confirm with almost near certainty, 99.999%, that it came from another solar system. The government gave Loeb a 10 km (6.2 mile) radius of where it may have landed.

“That is where the fireball took place, and the government detected it from the Department of Defense. It’s a very big area the size of Boston, so we wanted to pin it down,” said Loeb, “We figured the distance of the fireball based off the time delay between the arrival of blast wave, the boom of explosion, and the light that arrived quickly.”
