It’s this second type of potential “probe” that has attracted the attention of scientists, including Harvard astronomer Avi Loeb. In addition to suggesting that Oumuamua might have been an alien spaceship, Loeb, who holds a Ph.D. in plasma physics, has also searched the bottom of the ocean for evidence of alien visitors. These ideas, however, are not widely accepted in the greater scientific community. more
