    Pad ;

    What if the bright halo is nothing more than the flow energy in a cycle of ; dark-light-dark-light-dark-light , and so on.

    Just saying

    Hm. Let's made a rough estimate. If we consider only dark matter (not "dark energy", which is anyway only an exotic name for Einstein's cosmological constant), then there should be something like 80% DM and 20% usual matter. Assume now it is homogeneously distributed in the galactic plane. Which is not the standard assumption, because according to it is located in a spherical halo, which leaves much less of it for the galactic plane.

    Now, the Saturn is around 1 light hour away from the Sun (80 min or so), the next star 4 Lj away, thus, we can assume an average 4 Lj cube around each star which contains the dark matter corresponding to this star. Assume DM is homogeneous in this cube. It should contain 80% of the mass, thus, 4 times M⊙. How much will be inside the cube with 2 light hours? (2 h/ 4 years)^3. Which gives roughly 2 10^-12 M⊙. Compared with < 1.7 10^−10M⊙ there is yet a lot of room for not being bothered yet.

    So, only dark matter theories which predict that it has to be gravitationally catched by stars so that most of it is localized near the stars would be endangered.

    A cool , very cool photo

    photos of space filaments, the site is copy right it seems.

    If you put in " photos of space filaments " you will get some very cool photos.

    DM and baryonic matter.
    And what if it is a couple of spaghetti monsters having sex!

    I see that as a reasonable assumption to make in actual fact.

    Many reputable references so far that debunk this so called "paradox" or anomaly of DM, do so easily by considering the simple fact that when comparing the DM to baryonic matter within the solar system, the effects of the DM are way less than the effects the DM produces on our galaxy, or any galaxy as a whole.
    The density of normal baryonic within the solar system, is far greater than the density of baryonic matter within the galaxy, so therefor the effects of DM on solar system dynamics is negligible when compared to the effects it has on galactic dynamics and the far less dense scenario.

    Couple that with the clumping and obviously uneven distribution of DM, and just as obviously any imagined paradox can be ignored.

    And this is exactly what the authors of the following paper say.......
    http://arxiv.org/pdf/1306.5534v1.pdf

    Constraints on Dark Matter in the Solar System
    The same authors by the way that are referenced in post 141
    Nowhere do they surmise, say, predict, infer, or stipulate, in any way shape or form, that DM does not exist.



    In essence then it is easy to observe how those on this forum, taken with the "dark side of the force" [

    If couple of mainstream guys tell you that, then you will treat that as most logical and reasonable scientific explanation based on sound observation ! Thats Paddoboy.

    For you, Science is what comes out of their mouth, rest all is Pseudoscience. If you were born in the era of Copernicus, Galileo or Newton...then you would have declared these guys also as cranks etc..

    In earlier days, people would participate in arguments after reading, understanding, assimilating and then expressing in words or writing but for you, Paddoboy, these Machines with keyboard and mouse are doing this job...Google, then <CTRL><A> and then <CTRL><C> and then <CTRL><V> in a different tab.....thats scientific argument for you. Most logical and reasonable. Most of the time you are not aware what you have pasted. I see you are pasting articles having some maths, but you do not even understand middle school maths.

    Two arguments that our science trolls and crank nuts use often...[1] Claim the others don't think outside the box.[2] Call it pop science.
    Similar to the argument by conspiracy nutters who claim that all government official stories are a cover up.....Both are as nutty as each other, and one in all liklehood leads to the other.....science trolls/cranks and conspiracy nutters are equivalent.
    Yet all they have [the god and rajesh in particular] are forums such as this to spew their pseudo scientific crap.
    Do better my boy.

    Yep, certainly! far more sensible and logical than listening to nutters such as rajesh and those that suffer with delusions of grandeur such as yourself.
    No not at all, in fact I have shown I'm quite progressive and also alert enough to fathom out frauds such as yourself and rajesh.
    Again that will certainly continue to support all my arguments and debunk your nonsense when necessary.
    You on the other hand, sprout, spew and continue to make fraudulent claims evident by your own non professional, non expertise and idiotic manner.
    I'm always aware of what I post, although my maths is basic.
    Your own maths is also near non existent as Professor Bennett Link showed and couple that with your other unevidenced claims, and the evidence shows you for the troll and fraud that I have labelled you with.
    And supported by those that have you on ignore.

    Padoboy,


    Thats shows your ability (or lack of it).

    World needs people like you...absolute brainless followers...

    You staring at yourself in that mirror again my boy...such conceit, such stupidity, such false indignation, and as usual such arrogance!

    Here's some more "pop science" again for you.

    The story of the Universe has its fundamentals, core of galaxies, rotation of and , suns, planets, moons

    In essence the story of the Universe is approximately as detailed in the OP, and most certainly as shaped by gravity.
