Gravitational Wave Detection Imminent?

Seumas Hyslop writes "The UK Telegraph is reporting that we may finally have equipment that are sensitive enough to measure gravitational waves, which are incredibly small and have evaded detection despite the theories that they are present as a way of explaining gravitational effects. Basically, a laser beam is split into two branches that are sent down two identical 2000 feet long tubes and back again via mirrors. Assuming the two arms remain exactly the same distance, they will cancel each other out. But the scientists think that the beams will interfere with each other owing to the effect of gravity, meaning the length of the branches is altered and a gravitational wave has been detected."

    It really says a lot about the maturity and professionalism of the admins here that they would punish the people who point out the mistake, instead of actually fixing the mistake.

    Follow the guidelines for moderation. Moderate UP not DOWN. And browse at -1 Newest Posts First, No Threading.

    I know the rules. Preferably moderate up, rather than down. But one reason for moderation is to remove the clutter of trolls, off topic and so on for most people. A negative moderation os not automatically a bad moderation.

    I metamoderate three times daily and anything that is modded offtopic or flamebait or troll that isn't obviously so will earn you black mark that will reduce your chances of being selected as a moderator again.

    Good. Too few people are metamoderating.

    Of course, a discussion about spelling mistakes is almost always off-topic, as is commenting on it being a dupe. If it's at 2 already (probably because of Karma), it is very likely overrated as well. I can't be doing too badly with my moderations; I've gotten an "unfair" less than half a dozen times in the past few years.

    And naturally, this whole discussion right here fully deserves to get modded down too.

    That's not the point - the point is that it happens to be the job of the editors to correct such mistakes, and it's appalling that they do not take notice of something like this on the title of a new submission, no less. And while I was a subscriber, I've pointed out several such mistakes which would just be ignored time and again.

    An occasional mistake or two is one thing, but repeated ones are something else entirely.

    And as so-called geeks who can be sticklers about rules in programming and in a programming language, why should you treat natural language any differently?

    It's got a proper way of spelling it, and spell it that way. And in some ways, I'm at least glad that there are some of us who care enough about the language to point out a mistake.

    Sorry, some of us happen to appreciate proper usage and good spelling - and if there're so many folks pointing out the mistakes time and again, maybe there is a reason?

    Spelt is the original British usage, however American English does not seem to use that form, and uses spelled instead.

    My highschool English teacher would fail me for using spelled in the place of spelt, my American professor would frown and perhaps even point out my mistake (and her ignorance).

    I'd like to point out that these people could not point it out over and over again if it didn't keep happening over and over again. I think it wouldn't be that hard to have someone with at least a loose grip on English look over the news article before it was posted, and perhaps that same person could do a quick search through the old articles to make sure it hasn't already been posted. Also, if it was fixed immediately, there would not be much of a problem either.
