Harvard Astronomer Revels in Spaceship Theory - Is it? or Isn’t it?
Other experts in his orbit would like him to just shut up about it, but Avi Loeb, chairman of Harvard University's astronomy department, remains insistent a piece of an alien spacecraft has been observed inside our solar system in recent months, The New York Times reports.
The whole thing started late in 2017 when astronomers in Hawaii discovered an object the dubbed Oumuamua. (Hawaiian for "scout.") Oumuamua is the first known interstellar object ever found. Astronomers know it came from another star because of the speed with which it moved past the sun. But no one really considered it to be anything other than organic in nature — except Loeb and his colleague Shmuel Bialy.
While alien enthusiasts where naturally enthused, the academic community gave them a less than, say, stellar, reception. Most of Loeb's peers believe Oumuamua is rock of some sort, perhaps an asteroid or a comet now out of its place. But Loeb says it is moving too fast to be a rock, moving away from the sun as if being pushed.
