  • Large uncertainties’ Scientists dismiss Harvard paper’s ‘alien spacecraft’ theory

- Some Harvard astronomers claim an object spotted in the solar system could have been an alien spacecraft that was investigating our part of the galaxy.

Earlier this week, researchers from Harvard suggested it "may be a fully operational probe sent intentionally to Earth vicinity by an alien civilisation".

AFP asked Dr Bialy if he believed his claim. They say this "unexplained phenomena" means it would have to have a "very large surface and be very thin", which they say is "not encountered in nature".

But other astronomy experts aren't buying it.

"Like most scientists, I would love there to be convincing evidence of alien life, but this isn't it", said Alan Fitzsimmons, an astrophysicist at Queens University, Belfast.

Fitzsimmons added that Oumuamua's observed characteristics have already been shown as "consistent with a comet-like body ejected from another star system", while "some of the arguments in this study are based on numbers with large uncertainties".

Also Wednesday, NASCAR penalized the teams of Ryan Blaney and Erik Jones , who already have been eliminated from the playoffs. The whopping penalty negated the automatic berth Harvick earned into NASCAR's version of a final four.

This development also led notable American astrophysicist Katherine Mack to remark that "scientists are perfectly happy to publish an outlandish idea if it has even the tiniest *sliver* of a chance of not being wrong".

"But until every other possibility has been exhausted dozen times over, even the authors probably don't believe it, " she cautioned.

"It is impossible to guess the goal behind Oumuamua without more data", Loeb was quoted as saying.

The mysterious cigar-shaped interstellar object, which is apparently the first known object from another solar system to pass through our own, left some members of the scientific community wondering whether it is merely a space rock or some kind of alien craft.

Now, a paper submitted to the Astrophysical Journal Letters by a pair of Harvard researchers tackles that hypothesis as one way to explain the speed in which it blasted past the sun.

The alien rock is about 1,300 feet long (400 meters) long, and only about 130 feet wide.
