Study Concludes "Planet" Was Just Stellar Spots
Kligat writes "Back in January, it was reported that the youngest planet ever to be discovered, about ten times the mass of Jupiter, was orbiting the eight- to ten-million-year-old star TW Hydrae. Now a Spanish research team has concluded that TW Hydrae b doesn't exist, and that cold spots on the star's surface actually produced the dip in brightness instead of a transiting planet. Not as cool as if a planet had actually been there, but refutations are science, too, right?"
And I had just bought real estate there too! Think they'll give me my money back if I ask nicely?
Talk about a not-so-real estate bubble.

This is all part of the process of science.
People are trying to figure out the unknown, and don't always get it right the first time.
The popular press may spin it differently for the layman, but this is how science works.
In the 1940s, 61 Cygni was thought to have planets a planet -- then several planets, then none, and now, at least one.It's another example of science correcting itself more than once!
This sig seemed like a good idea at the time....
Frankly, I think the CS'ers (Cold Spotters) are just trying to debunk established scientific facts with fantastic claims that are based in conjecture. All of us Transitional Planetists need to make sure these clowns don't teach this shit in our schools!
This is where I sit back and watch the establishment piss themselves to mod me down first.
I doubt it, because most other measurements were based upon the apparent wobbling of the parent star, not direct observation. This one, AFAIK, was tied to an attempt to "see" the planet transition across the parent star. Actually, I was of the frame of mind to think this is almost as exciting (if not more so) than a planetary discovery. If we can detect "cold spots" on an alien star, there's all sorts of fascinating implications.
From the article:
Impressive! There's a lot we may be able to learn about our own sun by monitoring the daily happenings of other stars. Things like the frequency of solar maximums, sunspots, and so forth on other stars comparing them with our own would be one such course of study.
He who has no
Your post fundamentally disturbs me... and for a number of reasons.
I say this every time a science post like this is posted: modern science is a joke. What I hate the most is the very concept of theories.
Theories are pretty much entirely what science is about - so, if you have a problem with theories, you have a problem with ALL science, not just "modern science"
The idea that some half-assed guess gets passed around as an acceptable explanation until proven otherwise just strikes a nerve with me. I wish science would stick to black and white, "we know this" and "we don't know this".
Science has never been "black and white" and never will be. If you want that level of certainty, you'll find religion a few doors down the hall.
Theories are also not "half-assed guesses" - they're "best guesses" based on the results of experimentation (note that in some sciences direct experimentation isn't possible, so instead, precise modelling from the available evidence can also be used - this includes most of astronomy and historical things such as large timescale geology and evolution (both geology and evolution on short time scale, we've got experimental science already)).
If you walk in to the room, and I look at you, I can form a hypothesis, almost immediately, based on visual evidence, that you are human. If I then ran some tests based on my hypothesis and they agreed that with the hypothesis, then I'd have a working theory that you're human. I'd probably be right, however I can never know for sure - maybe you're an alien that just happens to be "human enough" that all of the tests I did would pass you as human. Now, I will work on the idea that you're human based on this theory. If however, a few weeks later, I get access to a new kind of DNA test, and for some reason decide to test you again, and find out you're NOT human, then the scientific method has NOT failed. I've determined you're not human, but I ALSO know with a lot more certainty how close to human you are (enough to pass all my initial tests).
That can relate back to the topic at hand by saying that we now know a lot more about HOW spots on a distant sun can LOOK like planets.
Stop this "we think this and that, have no real clue, but are going to pat ourselves on the back for pretending to know something we don't".
I wonder if perhaps you're just not familiar with what makes a theory compared to a hypothesis. Self-congratulations because of a hypothesis, would be bad, but self-congratulations because of a theory are definitely in order if it's interesting enough.
Science doesn't claim to know anything. Scientists will happily pat themselves on the back for a new theory, but anyone who then calls it "fact" is being intellectually dishonest (or perhaps just lazy, which is actually fine if they're not doing it in information that they're actively disseminating). Imagine, after my discovery that you're an alien, I throw a bit of a party because my theory now points to there being alien life on Earth. That party is pretty well justified I think, and some self-congratulation is definitely in order (if I'd thrown a party just after you walked in for looking at you and saying, "yep, that's probably a human" (or even, "yep, that's a probably an alien"), that'd be pretty stupid as I hadn't done any tests to try to confirm it). Then however, a few weeks after that, it turns out that some humans can have the strange DNA traits I found in you. I've gone from thinking you're human, to thinking you're an alien, to it turning out you're probably human after all. I'll say, "oops, looks like my theory was incomplete - sorry for the false alarm everyone!" and that should be fine. Even though I found out you're not an alien, I now know more about what I'm looking for next time, and also I've just learned something new about humans, so it's still a good thing. At this point, I assume you're human, even though I've changed my mi

Scientist 1: "OMG! There's a tear in the cosmic fabric of space-time! It's swallowing galaxies, heading right for us, and we're all going to DIE!"
Scientist 2: "Would you chill out? It was just a hair on the eyepiece. Look again."
Scientist 1: "Oh. Right. Well, that's enough science for this morning. I think I'm going to break for lunch, now..."
How many other 'facts' about things in the universe might merely be tainted observations?
Likely, several. But that doesn't lessen the value of the work at all. If something appears to work in a particular way, it probably does. If it turns out it doesn't, then the last body of evidence isn't just "thrown away" - it's just tweaked a little more - the previous assumptions, even if wrong, can still serve a useful purpose for explaining things.
Right now, we're pretty certain that there's a black hole at the centre of most (or maybe all) galaxies. We might be wrong. There might be a large, as yet unknown, type of gravity source there that is NOT a black hole. If that turns out to be the case though, it's not a bad thing for science - since every model so far works nicely with a black hole in that position, it will continue to work with a black hole in that position even if there isn't one. Just as Newtonian physics is wrong, but still serves as a very useful set of mathematics for most situations.
So many times I read the most fantastical things astronmers have discovered a billion light-years away, and I think, how do they really know that? When there's that much distance, couldn't there be something out there fooling with their observation?
Yes, there could - which is why we do lots of experiments regarding the kinds of things which may mess up observations as well. Could there be other things? Absolutely. Could that mean we're wrong about a lot of stuff we're observing? Yes, it could. Would that be catastrophic to science? Not at all - we'd have a lot of new things to study! We can build up a very accurate but completely incorrect model of the universe and as long as it's valid from our frame of reference, it can be useful for doing things.
Imagine if it turns out that MOND is probably correct - it doesn't automatically mean all the research in to dark matter has been wasted - a lot of that research could be used as "test cases" for MOND, to help "prove" it. If any of our information about dark matter gave results that could NOT be explained by MOND, we'd have to concede that either the observations are wrong (and then explain how), or that MOND is wrong. Either way, we enhance our understanding, which is good.
and I don't believe it is just the public mis-interpreting something that the scientists said was 'probable'. A lot of these guys pass off their discoveries as facts.
Anyone who does so is being dishonest - that's a problem of the people explaining the science, not of the science itself. That said though, if anyone ever tells me something is "fact", I take it to mean, "all current evidence points towards this being the case and we can't imagine any realistic way that this could not be the case". So, even if some scientists are being dishonest and saying something is fact, then it's STILL the public's misunderstanding of science that is at least partly to blame if they get all upset when new data points to a different answer. I myself am dishonest in this exact way whenever I tell someone that "gravity pulls you down towards the earth", or "We evolved from simpler life over a LONG period of time". I am presenting these theories as facts, because any alternative is completely inconceivable to me, and it's just quicker than explaining, "Given all the available evidence, it appears as if, from your reference frame, gravity will pull you towards the earth". For less well entrenched theories, I tend to avoid such strong statements, and prefer the "longer" explanation, but the meaning should be considered pretty much the same. If clarification is needed, then you should ask how strong the evidence is that points to this theory being correct.

Also, for whatever it's worth, there have been rumors floating around since the original announcement that several groups have photometric data showing the variations in stellar flux due to these spots. The period of this variability was supposed to be consistent to the "planet's" period, a very strong argument that it was a rotation/spot effect.

What I want to know is this: At what point in the history of Slashdot did it become necessary to explain and defend the fundamental philosophies of science?
