Scientists push back against Harvard 'alien spacecraft' theory [Oumuamua]
Agence France-Presse ^ | 6 Nov 2018

A scientific paper led by two researchers at Harvard University made a splash this week by claiming that a cigar-shaped rock zooming through our solar system may have been sent by aliens.

The researchers noted in a pre-print of the article that it was an “exotic scenario,” but that “Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization.”

Oumuamua, the first interstellar object known to enter our solar system, accelerated faster away from the Sun than expected, hence the notion that some kind of artificial sail that runs on sunlight — known as a light sail — may have helped push it through space. […]

Their suggestion of an alien force at work went viral.

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.

“It has already been shown that its observed characteristics are consistent with a comet-like body ejected from another star system,” he told AFP. “And some of the arguments in this study are based on numbers with large uncertainties.”

Katie Mack, a well-known astrophysicist at North Carolina State, also took issue with the alien hype. “The thing you have to understand is: scientists are perfectly happy to publish an outlandish idea if it has even the tiniest sliver of a chance of not being wrong,” she wrote on Twitter. …

Yep. Just watch any Star Trek movie related to time travel. It’s all explained there. :-D

The Mother Cigar?

Too bad it’s going the wrong way, from the NOI perspective.

Just looking at its trajectory line alone almost disturbs me.

That thing didn’t just come here that way all on its own.

Natural or artificial, it’s an unknown that is eerie.

Oh, I was thinking Farrakhan.

This object looks like a Baby Ruth in the pool, right?

5.56mm

One of the other astronomy experts is a woman so, we must believe her.

Outgassing as ice melted. If it did so at closest approach, that’s a de-facto Gravity Well maneuver, aka a “slingshot”. . .

Ablation? The heating effect on the object caused it to lose mass. Comets do this when they form ‘tails’. Somebody would have to run the numbers though.

in 60 some years of ‘aliens’, not a single one has landed on the WH lawn and asked to see our leader. If I was a friendly alien, I might want somebody to know that I put a lot of effort into getting to Earth to say hello. And if I was an enemy alien, I wouldn’t care who saw me.

That’s because they met with Truman at Murock AFB (aka Edwards) not the Whitehouse.
