New Study Shows Solar System Is Uncommon

Iddo Genuth writes "Research conducted by a team of North American scientists shows our solar system is special, contrary to the accepted theory that it is an average planetary system. Using computer simulations to follow the development of planets, it was shown that very specific conditions are needed for a proto-stellar disk to evolve into a solar system-like planetary system. The simulations show that in most cases either no planets are created, or planets are formed and then migrate towards the disk center and acquire highly elliptical orbits." The research was published in Science magazine; here's the paper on ArXiv (PDF).

    I wouldn't read it like that

    Space is still the big unknown. If this "shows' anything, it seems more probable that this 'shows' that the simulations aren't complete enough yet.

    If they would deduce this from actual statistical data, it would show something, but deducing this from simulation seems a a bit to trustful to the current state of science if you ask me

    If even one thousandth of one percent of stars form solar systems similar to this one, that would still be quite significant.

  3. Under which model? by Xiroth · · Score: 5, Insightful

    I have to ask: Under which solar formation model was this conclusion drawn? Because from what I understand, there are a number of competing theories, none of which have come anywhere near being conclusively proven. I actually studied under the creator of one of the models, Andrew Prentice, and was in a position to watch as the predictions of various hypotheses were proven true or false. We've got a long way to go in the field, from what I understand.

    I agree. Basing conclusions off simulation models is risky, mainly considered how in the domain of planetary simulations, well established models get entirely questioned every once in a while.

    And at this point even actual statistical data is hard to use to conclude anything about our solar system, because of our limited observation capabilities, what we know has a heavy statistical bias.

  5. Climate Science by bencollier · · Score: 5, Insightful

    I dislike pointing this out, but that's an interesting parallel with climate science. I remember hearing recently (on Slashdot?) that climate models primarily base their data on one or two sources that, if altered slightly, would throw the simulations pretty severely, one way *or* the other.

    Research conducted by a team of North American scientist shows our solar system is special

    ... therefore, God created this solar system specially for man, which is the center of the Universe.

    I love this based-on-new-studies "science".

    Just because we can't see (yet) any other kinds of solar systems, doesn't necessarily mean ours is "special" !
