Avi Loeb, a scientist, believes that we are not alone in the universe. The belief fits with Loeb's alien spaceship theory that at least one alien spaceship might be flying over the orbit of Jupiter, which won the international attention last year.
Astronomers in Hawaii found the first known interstellar object in late 2017. It was a bit of light moving so fast past the sun that it could only have come from another star. Almost every astronomer on the planet was trying to figure out how the object, called “Oumuamua” got to our far-away part of the Milky way galaxy. “One possibility is that ‘Oumuamua’ is debris from an advanced technological equipment,” Loeb said. “Technology comes from another solar system just showed up at our door. ”
“‘Oumuamua’ is not an alien spaceship,” Paul Sutter, another scientist wrote. He suggested Loeb was seeking publicity. Most scientists think “Oumuamua” is some sort of rock. They think it could be an icy wandering comet.
Loeb says that “Oumuamua's” behavior means it can't be a block of rock shaped like a long photo. He thinks it's more likely an object that's very long and thin, perhaps like a long pancake or a ship's sail. Loeb says that if someone shows him evidence that contradicts his beliefs, he will immediately give in.
Loeb believes himself a truth-teller and risk-taker in an age of very safe, too-quiet scientists. “The worst thing that can happen to me is that I would be relieved of my management duties, and that would give me even more time to focus on science,” Loeb says. He said he wouldn't mind giving up all the titles he had and returning to the Israeli farming village where he grew up.
