That gives them tenure, autonomy, and more research grants in their field. They're disincentivized to actually spend any time engaging with the public,” Fraser Cain, the publisher of Universe Today and co-host of Astronomy Cast, explained to me in an email. "}},{"type":"paragraph","data":{"text":"“The only scientists you see regularly engaging with the public truly enjoy it or feel passionate about educating the public (or to publicize an upcoming book), despite the lack of support from their institutions. And I know, from us as outsiders, that seems really bizarre, since more press helps their university, which gets them more students. Scientists should be encouraged to engage with the public, but they're not. It's a really bizarre cycle, that's somehow got a missing link that I haven't been able to tease out yet,” said Cain.

"}},{"type":"paragraph","data":{"text":"Ever the maverick, Avi Loeb throws up his hands when I mention the slogan. “Extraordinary is a very subjective thing and depends on how you view things. You might even say that the Earth moving around the Sun is extraordinary.” "}},{"type":"paragraph","data":{"text":"The salience of Carl Sagan’s iconic neologism strikes at the very core of the controversy over ‘Oumuamua. "}},{"type":"paragraph","data":{"text":"To his credit, Fanelli offers a pure, good faith interpretation of the maxim’s focus on evidence rather than dogma. “That doesn’t mean that challenging and unorthodox views should be impeded, and that the challengers should be ostracized. They should be encouraged to expound their views. But resisting new ideas and requiring high standards of proof is quite literally the job of peer reviewers,” explained Fanelli. "}},{"type":"paragraph","data":{"text":"Likewise, Loeb isn’t wrong in denouncing how the phrase, dubbed the “Sagan Standard,” is often applied. Rather than encouraging scientific inquiry in pursuit of incredible answers, the aphorism has often been used as a means of suppressing incredible questions.

The likelihood of finding demonstrative proof of what exactly it is at this point is very remote, if not impossible.

"}},{"type":"paragraph","data":{"text":"For the vast majority of academia, scientific progress represents “development-by-accumulation,” whereby accepted facts and theories slowly nudge knowledge forward.

"}},{"type":"paragraph","data":{"text":"In The Structure of Scientific Revolutions, Thomas S. Kuhn argued that the discovery of “anomalies” leads to new paradigms, which then ask new questions of past data, moving science beyond the mere puzzle-solving stage toward mapping out an entirely new direction of scientific research.

Like Loeb, Kuhn was labeled a heretic and criticized for his claims. "}},{"type":"paragraph","data":{"text":"Scientific progress depends on innovative ideas. Yet, under the accepted standards of empirical inquiry, a host of published and peer-reviewed research illustrates the scientific community’s extreme bias against novelty.

"}},{"type":"paragraph","data":{"text":"“In theoretical physics you find concepts like extra dimensions, supersymmetry, superstring theory, the multiverse — that are all considered mainstream, and people give each other awards for engaging in intellectual gymnastics on all these concepts.

"}},{"type":"paragraph","data":{"text":"“All these people who popularize science, they talk about it and act like it’s really frontier. But it's not really frontier! It has no connection to us. They don’t put any skin into the game. The only way for a theoretical concept to be scientific is when it puts skin in the game. If you say, ‘I predict this!’ And if you do the experiment and don’t find this, okay then my theory is ruled out.” "}},{"type":"paragraph","data":{"text":"Loeb expresses intense displeasure at the idea that extreme theoretical concepts like string theory should be considered acceptable while his suggestion that alien objects may pass through our solar system is treated as clownery. “These people, if you say, ‘Okay, can you make a prediction? Is there an experiment you can envision that would rule out your theoretical idea?’ And they would say, ‘No, whatever the experiment finds, I will be able to accommodate that.’ Is this science?! How can you call yourself a physicist if you don’t pay attention to reality!?!” "}},{"type":"paragraph","data":{"text":"Loeb’s overarching argument is that science should be willing to consider and investigate the material, rational, and testable possibility that alien technology is zipping by us much too close for comfort for some. “There could be a lot of objects, many more, flying closer to us, but much smaller in size. Or also objects traveling faster, that we never recognize with our telescopes right now,” said Loeb. "}},{"type":"paragraph","data":{"text":"To his most trenchant detractors, Loeb flashes a mischievous smile. “My suspicion is that many of the harshest critics really are intrigued by the possibility that alien life exists, but to hear someone speak out, it is opposite to their inner compass.” "}},{"type":"paragraph","data":{"text":"Watching his passion as he rebukes critics and demands the institutions of science be more open-minded, one thing seems certain. It’s unlikely Avi Loeb is going to back down and fall in line with conservative academia anytime soon. “This possibility that life exists elsewhere is the conservative choice. The other possibility is the fringe,” Loeb smiles. "}},{"type":"paragraph","data":{"text":"According to Ulukau Hawaiian Electronic Library, the word ‘Oumuamua means: “a leader, as in battle or other activity; a scout.” Reflecting on its name in this light, ‘Oumuamua seems a fitting partner for Dr. Loeb’s obstinate battle, the battle for science to shed its biases on the possibility of alien life.
