The Major Theoretical Blunders That Held Back Progress In Modern Astronomy 129

KentuckyFC (1144503) writes "The history of astronomy is littered with ideas that once seemed incontrovertibly right and yet later proved to be bizarrely wrong. Not least among these are the ancient ideas that the Earth is flat and at the center of the universe. But there is no shortage of others from the modern era. Now one astronomer has compiled a list of examples of wrong-thinking that have significantly held back progress in astronomy. These include the idea put forward in 1909 that telescopes had reached optimal size and that little would be gained by making them any bigger. Then there was the NASA committee that concluded that an orbiting x-ray telescope would be of little value. This delayed the eventual launch of the first x-ray telescope by half a decade, which went on to discover the first black hole candidate among other things. And perhaps most spectacularly wrong was the idea that other solar systems must be like our own, with Jupiter-like planets orbiting at vast distances from their parent stars. This view probably delayed the discovery of the first exoplanet by 30 years. Indeed, when astronomers did find the first exo-Jupiter, the community failed to recognize it as a planet for six years. As Mark Twain once put it: 'It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so.'"

    Yes, The Academy laughed at your ideas. They also laughed at The Three Stooges.

    Sometimes, reviewers reject radical ideas that turn out to be correct. Far more often, though, they reject radical ideas because they're demonstrably ridiculous. You might be the next unsung genius, with the crazy idea that will make all the pieces fall into place. It's far more likely that you're a crackpot.

    Suppose one rejected idea in 1000 is actually a revolution in waiting. (I suspect that ratio is generous at best.) Now, suppose we publish one (or ten) rejected ideas in every issue of our journal. How many of those rejected ideas will turn out to be worthwhile? How long will people put up with the "alternative views" section of our journal before they just start skipping them?

    ... the more we realize what we do not know.

    .
    Isn't this what science is about? Discovery, exploration, learning.

    Of course mistakes will be made along the way. The fact that we can look back and see those mistakes for what they are is a part of the scientific process.

    This is a good thing.

    Gee, the telescope size limit. Guy proposes that they shouldn't be bigger - everyone on the west coast ignores him, build bigger. It may have held back a small group of astronomers, but...
    X ray Observatory. It delayed things 5 WHOLE YEARS! GASP. Yes, I realize that the /. crowd is heavily biased to young males, but guys, it is to the point the average college student doesn't graduate in 5 years. I've got bottles of booze that I haven't had a drink out of older than that, and projects sitting on my workbench longer than that. One of my dad's HOBBY projects took 3 hours a night, every night for 8 years.. The only one I'd call at ALL significant is the 30 years

    It turns out that the history of astronomy is littered with ideas that once seemed incontrovertibly right and yet later proved to be bizarrely wrong.

    Yes. In different words, there was "scientific consensus" on them. Remember that next time people throw that phrase around to convince you of the correctness of some idea.

    “Because Jupiter is considerably farther out from the center of the solar system, time allocation committees on major telescopes declined proposals to search for close-in Jupiters for years based on the argument that such systems would deviate dramatically from the architecture of the solar system and hence are unlikely to exist.”

    And this is why it takes so long to overturn false scientific consensus. Scientific "conspiracies" aren't conspiracies of evil masterminds, they are merely mobbing using peer reviews and grant committees.

    And the original article does not make the avoidable blunder of including a the concept of a flat earth in the list of avoidable blunders. Because the flat earth concept actually has been avoided from the beginning.

    There are some people who just won't get that "scientific consensus" is an oxymoron. Sometimes in general other times in quite spoecific cases.

    And this is why it takes so long to overturn false scientific consensus. Scientific "conspiracies" aren't conspiracies of evil masterminds, they are merely mobbing using peer reviews and grant committees.

    Often they arn't even any kind of "conspiracy" at all. More of a belief of "everyone knows X to be the case" with some logical fallacies (and egos) to prop things up.
  • It delayed things 5 WHOLE YEARS! GASP. Yes, I realize that the /. crowd is heavily biased to young males, but guys, it is to the point the average college student doesn't graduate in 5 years.

    It's not so much that it's biased towards young males, it's that it's heavily biased towards people who have the attention span of the MTV generation and who don't really grasp delayed gratification. They grew up with instant availability of anything digital via the internet, and if it's a physical thing it's available quickly because two day shipping is now the norm.
     
    That's a generalization of course, and there are exceptions... But I'm fifty and many people that I've met that are under about thirty five or so don't readily grasp timescales longer than a week or two. They know that such things exist, but they don't really think on that timescale.

    Indeed. I just made tentative travel plans for 2015 (high school reunion) and solid plans for 2016 (SSBN crew reunion)... Some of us from high school are already pondering as far out as 2021 (our 40th anniversary). I'm halfway through my six year plan to re-make my workshop. I just started a five year long project experimenting aging vodka with toasted and charred chips of various woods, and I just set down a batch of my custom whisky blend aimed at being ready for for the holiday season. Etc... etc...

    Set against the scale of human history, thirty years is nothing. Five years is less than nothing.

    Here's the deal on 'scientific consensus' -- it's not always right, but it is the best guess at the time, supported by the majority of the evidence by smart people who know the subject. Anything else is more likely, not certainly, but more likely, to be wrong. You place your bets, you take your chances. If I need treatment for my cancer or degenerative disease, I'm going with the scientific consensus. If I'm designing a bridge or airplane that will carry passengers, I'm going with the scientific consensus. If I'm making a long term investment (in land in Florida as a random example), I'm going the scientific consensus. If I'm writing my own crackpot blog or political screed or investment scam newsletter, then maybe I don't go with the scientific consensus ...

    The first idea presented is awfully weak:

    In an article on the future of astronomy published in 1908, he wrote: “It is more than doubtful whether a further increase in size is a great advantage.” His argument was that factors other than size had a much bigger influence on astronomical data, factors such as climate. “It seems as if we had nearly reached the limit of size of telescopes, and as if we must hope for the next improvement in some other direction,” he said. Loeb says Pickering’s views had a major impact on observational astronomy on the east coast compared to the west coast of the US. Just as Pickering was publishing his controversial idea, the 60-inch telescope at the Mount Wilson Observatory near Los Angeles, saw first light. And while astronomers in the east were arguing the toss about size, this telescope was gathering the data that would eventually make it one of the most productive in astronomical history. What’s more, at exactly that time, the Mount Wilson observatory received funding to build a 100-inch telescope and this was completed in 1917. And this was in turn superseded by the 200-inch telescope at nearby Mount Palomar in 1947 which remained the largest telescope in the world until 1993.

    Pickering was right: a bigger telescope is not the answer when your site has poor climate, due to diminishing returns. Plus, from the article's own evidence, people kept building larger telescopes - they just put them in better places.

If you want to put yourself on the map, publish your own map.
