Recently Discovered Habitable World May Not Exist

sciencehabit better let Greg Dean know that "Two weeks ago, U.S.-based astronomers announced the discovery of the first Goldilocks planet circling another star: just the right size and just the right temperature to harbor alien life. But yesterday at an exoplanet meeting in Turin, Italy, Switzerland-based astronomers announced that they could find no trace of the prized planet in their observations of the same planetary system."

      This is not a reasonable assumption. Our models are at best simplifications of reality. Do atoms *really* exist the way we envision them? Is there such a thing as an electron as a real finite particle? it wasn't that long ago that we believed that atoms were indivisible, discrete particles of matter. Our new models make that look ridiculously naive. 100 years from now I think it is likely that our current models will look ridiculously naive.

      But older, naive models work fine for a lot of problems. We don't have to know how things *really* work at a low level as long as we can build a repeatable model that is useful for our tasks. The model can be (and almost certainly is) a black box with interfaces that we care about. Everything inside the box is up for grabs. Not knowing what is really going on inside doesn't affect our ability to solve our problem, so we ignore it (for now anyway).

      The question you have to ask yourself is if the Universe can have a description which is isomorphic to reality, but still different. I suspect that there are several such descriptions. There are probably even an infinite number of such descriptions. Which is the correct one? If the descriptions are isomorphic, then it doesn't matter for our purposes what reality is. But a model that is isomorphic to reality is not the same as reality.

      Why is this important? Because believing that science is true leads you into treating science as a religion. If you believe something is true, then you have a hard time changing it when it proves to be useful. Scientific models are meant to be useful. Assuming they are also true is very bad science.

      It wouldn't take a probe 400 000 years. Gliese 581 is in our own back yard, a "mere" 20 light years away. A probe can accelerate all the way, and then radio its findings back as it flies past. Using pulsed plasma propulsion, it can probably be done in 3-4 centuries.

      But, when something sounds to good to be true, it probably is. Whether it's a Nigerian president's widow wanting to share her fortune with you, a car that runs on water, or a Goldilocks planet in our own neighbourhood.

  10. Data Sets by BJ_Covert_Action · · Score: 5, Insightful

    Well it looks like the U.S. astronomers used two sets of data gathered from different time periods for their analysis. Meanwhile, the Swiss astronomers used a third set of data gathered over a different time period for their analysis. I would think the first thing that should be done would be to swap data sets. Have the U.S. astronomers run their analysis on the Swiss data set with their tools, and have the Swiss astronomers run their analysis on the U.S. data sets with their tools. After all is said and done, compare the results yielded by each data set. If only the U.S. astronomers are finding the gravitational wiggles, then it means that either their tools are inducing some kind of experimental error, or the Swiss tools are missing some critical component. At which point the tools and methods between the two groups should be compared and contrasted to observe differences.

    If, however, U.S. analysis of the Swiss data sets similarly yields a no planet result, and Swiss analysis of U.S. data sets yields a planet exists result, then you can conclude that the problem is in the data, and not the analysis being done. So, the moral of the story to both teams is to send their data to each other. For bonus points, both parties can publish all of their data so that a few third parties can conduct their own analysis. This is what science is all about after all folks!

        Don't underestimate the possibilities of mythical and theoretical equipment.

        Look at Star Trek, since others have used that imaginary universe in this thread already. Cloaking shields to make a ship or planet disappear. Sure, perfectly rational. The ships in the Star Trek universe have gravity plating. If you can create it, you can negate it. Why not? The good old "suspension of disbelief" stands firm. But why stop there. What if the planet (if it was one) were in a trans-dimensional state, where it could be seen but only sometimes has a physical presence.

        Or to step into one of my favorite imaginary universes, what if it was an object such as the Tardis. Hell, not only can it show up at any place, at any time in the universe (and sometimes alternate universe), but it can tow objects as large as a planet when needed. And of course, the door isn't a door, it's a transdimensional portal, so you're not stepping inside, you're stepping through. The physical "inside" isn't inside, it's actually somewhere else. Well, unless it's convenient for it to be effected by outside forces and the occupants are thrown around in a Star Trek like drama (Everyone lean left. Everyone lean right. Now fall down.)

    The American team used a combined set of observations: One 11-year-long set consisted of 122 measurements made by the team, while the other set was 4.3 years long and consisted of 119 measurements published by the consortium.

    [The Swiss group] used only their own observations, but they expanded their published data set from what the U.S. group included in its analysis to a length of 6.5 years and 180 measurements.

    So, the American study had 241 observations over at least 11 years and the data is peer reviewed and published. The Swiss apparently are refuting that by ignoring half the data and adding 61 data points from 2.2 years that haven't been peer reviewed. Obviously they're a reputable group, but I'll wait for them to look at *all* of the data available to them, preferably published data, before just taking them at their word. Doubly so for a negative finding since alpha (chance of a false positive) tends to be a lot smaller than beta (chance of a false negative).
