There is a strange object in space, Oumuamua, which some gerky science types are starting to think is, or was, an alien probe, cleverly disguised in rock, a kind of cosmic conspiracy sandwich:
“The odd interstellar object that zoomed through the inner solar system last fall might be an alien spacecraft with a light sail, a new study suggests. Indeed, an artificial origin would explain quite nicely the many weird characteristics of that cosmic visitor, which is known as 'Oumuamua, study co-author Avi Loeb said. And Loeb said his colleagues shouldn't dismiss this hypothesis out of hand just because it invokes intelligent aliens.
"That is a prejudice that we shouldn't have," Loeb, who chairs the astronomy department at Harvard University and directs the Institute for Theory and Computation (ITC) at the Harvard-Smithsonian Center for Astrophysics, told Space.com. "Science should be open-minded."
