What Space Object ‘Oumuamua Says About How Science Works

The space object, thought by at least one famed astronomer to be an ET lightsail, prompts thoughts about how scientists decide what to believe

The subtitle of Matthew Bothwell’s wrap-up on ‘Oumuamua is most informative: An alien-made artefact or just interstellar debris? What ʻOumuamua says about how science works when data is scarce. At least one astronomer, Harvard’s Avi Loeb, insisted that ‘Oumuamua must be an “extraterrestrial light sail.” And few suggested that that couldn’t possibly be true. Right. What do we do when we are not sure? Bothwell, author of the forthcoming Invisible Universe, offers some thoughts. W all imagine ET in our own image: Victorians of the late 19th century, living in the era of ambitious engineering, looked at Mars and saw globe-spanning canals – evidence, they believed, of a grand industrial civilisation mirroring their own. In the Cold War 1960s, as…

SETI Director Warns: Those Aliens Could Be Malevolent

Harvard astronomer agrees: We’ve sent a lot of signals in recent years; they may have got them. But now what?

As the Mars Rover Perseverance bumps around looking for fossil bacteria and such, many students of possible ET life are becoming surprisingly cautious about what it might mean: “We have no reason to believe that technological advancement and altruism or morality are somehow linked,” SETI researcher Andrew Siemion told Inverse. “There probably are malevolent civilizations elsewhere in the universe so that’s certainly something that we should consider as we continue to explore the universe.” Siemion, who’s the director of the Berkeley SETI Research Center and principal of the alien-hunting Breakthrough Listen project, is invoking a tension at the heart of any project searching for alien life. Successfully finding it would change the world — but there’s also no guarantee humanity…

Astrobiologist Cautions Against Jumping the Gun in Spotting ET

Scientists he says, are cautious with good reason. There are many weird natural phenomena like Oumuamua out there.

At Nautilus, astrophysicist (and astrobiologist) Caleb A. Scharf offers some sobering reflections on the diligent search for extraterrestrial intelligences (ET) in recent decades: Despite this effort, there has been no evidence to date of extraterrestrial life. But that lack of evidence is not because the scientific enterprise is uniformly conservative, rigid, and close-minded, as implied by [astronomer Avi] Loeb and uncritically echoed by some columnists. It’s because no discovery or event has risen to the level where it is inexplicable in any other way. Could greater funding and support change that story? Perhaps, but the same could be said for almost any other ambitious scientific enterprise, and the answer cannot be known beforehand. Caleb Scharf, “The Alien-Haunted World” at Nautilus…

Why Do People Who Believe in Extraterrestrials Dismiss Ghosts?

The talk about extraordinary claims requiring extraordinary evidence—or otherwise—misses the point. There is no evidence

A recent profile in Astronomy focused on Abraham Loeb (pictured) a Harvard astronomer who is convinced that closed minds are a key barrier to our finding extraterrestrials. Statistically, he thinks, they must be out there somewhere: About 25 billion stars, roughly one-quarter of those that reside in the Milky Way, lie in a habitable zone. He rounds that down to an even 10 billion to keep the calculations simple. “And then there are about a trillion galaxies like the Milky Way,” he says, “which means there are about 1022 [10 billion trillion] planets in the observable universe that could potentially host life as we know it.” In other words, searches for extraterrestrial life have barely scratched the surface. “As in…

Tales of an Invented God

The most important characteristic of an AI cult is that its gods (Godbots?) will be created by the AI developers and not the other way around

A book on the new pop science religion might well be titled “Tales of the Invented God.” Its author would likely be challenged to keep up with all the non-events breathlessly documented. After all, the technocrats who invent their future gods can change, re-envision, replace, upgrade, eliminate them at any time.
