Dark matter, neutrinos and tachyons in the same abstract? Oh yes:

According to conventional wisdom the 5-hour early Mont Blanc burst probably was not associated with SN 1987A, but if it was genuine, some exotic physics explanation had to be responsible. Here we consider one truly exotic explanation, namely faster-than-light neutrinos having sourcemν2=−0.38keV2. It is shown that the Mont Blanc burst is consistent with the distinctive signature of that explanation i.e., an 8 MeV antineutrino line from SN 1987A. It is further shown that a model of core collapse supernovae involving dark matter particles of mass 8 MeV would in fact yield an 8 MeV antineutrino line

    awesome as that is
    and decided it had to be dark matter.

    i'm glad these are not the people that write the code i depend on.

    it's worse than that.
    there's an unexplained event.
    they picked out an unrelated event, so that the math would fit, and said "if the unexplained event is related to this other event, then it's tachyons!".

    it's just like that thing where you take the length of the pyramid in inches and divide it by the Earths' diameter in kilometers and then you get Jesus's head circumference in a little known measurement unit.
    the technical term (careful, sciency word follows) is numerology.

    off-topic: sometimes i calm down and think exotic matter physicists are physicists too. then I run into stuff like this.

      what i find strange is that it is possible for a sailing ship to sail faster then the wind ... albeit not in the direction the wind is blowing.
      now i don't know how this is relevant to teh tachyon discussion; them being like a poop in a flaming brown paper bag at your physicists front door and all.

      but anyways, maybe the "sailing-ship-goes-faster-then-the-wind-is-blowing" analogy might be a useful one since using a car analogy, one might be
      hard pressed to explain tachyons?

      anyways, we better come up with a good analogy to explain tachyons, since else this post totally made me right it ...

        we don't have to explain something that doesn't exist.
        ok, so you can write down some equations that give you particles moving faster than light.
        that's meaningless until they make an experiment where their theory is confirmed.
        as far as objective reality is concerned, there is no experimental measurement that requires tachyons in order to be explained.
