Harvard's top astronomer says an alien ship may be among us -- and he doesn't care what his colleague

CAMBRIDGE, Mass. —Before he started the whole alien spaceship thing last year, the chairman of Harvard University's astronomy department was known for public lectures on modesty. Personal modesty, which Avi Loeb said he learned growing up on a farm. And what Loeb calls "cosmic modesty" — the idea that it's arrogant to assume we are alone in the universe, or even a particularly special species.

You can find a poster for one of these lectures in Loeb's office today, though it's a bit lost among the clutter: photos of Loeb posing under the dome of Harvard's enormous 19th-century telescope; thank-you notes from elementary-school children; a framed interview he gave the New York Times in 2014; his books on the formation of galaxies; his face, again and again — a bespectacled man in his mid-50s with a perpetually satisfied smile.

Loeb stands beside his desk on the first morning of spring courses in a creaseless suit, stapling syllabi for his afternoon class. He points visitors to this and that on the wall. He mentions that four TV crews were in this office on the day in the fall when his spaceship theory went viral, and now five film companies are interested in making a movie about his life.

A neatly handwritten page of equations sits on the desk, on the edge closest to the guest chairs.

“Oh, this is something I did last night,” Loeb says. It’s a calculation, he explains, supporting his theory that an extraterrestrial spacecraft, or at least a piece of one, may at this moment be flying past the orbit of Jupiter.

Since publishing his controversial paper, Loeb has run a nearly nonstop media circuit, embracing the celebrity that comes from being perhaps the most academically distinguished E.T. enthusiast of his time — the top Harvard astronomer who suspects technology from another solar system just showed up at our door. And this, in turn, has left some of his peers nonplused — grumbling at what they see as a flimsy theory or bewildered as to why Harvard’s top astronomer won’t shut up about aliens.

What you can’t call Loeb is a crank. When astronomers in Hawaii stumbled across the first known interstellar object in late 2017 — a blip of light moving so fast past the sun that it could only have come from another star — Loeb had three decades of Ivy League professorship and hundreds of astronomical publications on his résumé, mostly to do with the nature of black holes and early galaxies and other subjects far from any tabloid shelf.

It is a hypothesis that has other more parsimonious explanations.

You can never disprove his conjecture, but it fits into the same conjecture as about the Tunguska event.

Too many scientists are still too skeptical about the existence of extraterrestial life forms other than microbes.

Their arguments remind me of the dismissal of the possibile existance of extrasolar planets. Until Kepler proved they are common.

If extrasolar planets are as common as shown, then extrasolar life should be pretty common, too.

And precisely what conjecture of Tunguska are you speaking of? That it was something other than a Stony asteroid or comet?

During the press conference in Krasnoyarsk, Yuri Lavbin, the head of the last expedition, confirmed that parts of an extraterrestrial device had been discovered. The new expedition, organized by the Siberian Public State Foundation “Tunguska Space Phenomenon” completed its work on the scene of Tunguska meteorite fall on August 9.

The new theory suggests that the event was a collision of a meteorite with an alien spaceship. “They exploded this enormous meteorite that headed towards us with enormous speed,” Yuri Lavbin said. Now this great object that caused the meteorite to explode is found at last. We will continue our research, he said.

Also a later story.

The outgassing phenomenon affecting acceleration is known for other bodies of this type.

What happens when you plug into the expectations of the public of a first contact situation is that you skew expectations and later have to deal with the disappointment when a well publicized hypothesis is disproven or no additional credible data is forthcoming.

I thought the researchers involved with Tabby's Star did a much better job with tamping down expectations. The Mars meteor story of the 1990s was not well handled. I also thought the arsenic replacing phosphorous in the cell structure of a bacteria was also not well handled.

I am all for SETI. I would like for us to set up a program to examine 100 percent of the night sky looking for evidence of Kardashev 3 civilizations in galaxies out to 4 billion light years.

This has to do with the probability that extra-solar intelligent life built and launched an interstellar probe intended to reach us. Oumuamua has, from what I've read, shown any movement that would suggest other than natural gravitational influences, much less any speed capability consistent with a society capable of better than sublight travel.

It could be a probe, something like our own Voyager spacecraft maybe (well except bigger and if it really is accelerating under its own power, or with some kind of starlight-powered propulsion or whatever, somewhat more advanced).

It does seem an odd shape to come hurtling out of interstellar space. Weird.

Who knows, it could be some kind of space-animal or something.

I wonder what the public reaction would be, if it could be verified somehow. Like, if it comes back and establishes itself in orbit around the Earth or something, that would be pretty difficult to explain. The acceleration in and of itself is odd, but as long as it's not changing direction or otherwise moving in some evidently non-ballistic way, all that we'll have is speculation.
