I've always been uncomfortable with the fudge-factor physicists call Dark Matter/Energy and confidently act like is real. Would be nice to see it destroyed.

  I went down the mond rabbit hole a while ago, The bullet cluster is one of the things that makes mond hard to support https://en.wikipedia.org/wiki/Bullet_Cluster https://en.wikipedia.org/wiki/Bullet_Cluster

    Your link seems to suggest that it being proof of dark matter and against MOND was based on bad data that has since been rectified.

      Could be, this is interesting https://pursuit.unimelb.edu.au/articles/digging-deep-for-dark-matter https://pursuit.unimelb.edu.au/articles/digging-deep-for-dar...

  > the fudge-factor physicists call Dark Matter/Energy Those are two very different fudge factors (as in, those hypotheses are distinct; the observations they attempt to explain may turn out to have a single cause instead, but we don't yet know) > Would be nice to see it destroyed If you don't like fudge-factors, then you probably won't like MOND (the sort of hypothesis TFA is about). Edit: MOND theories put a fudge-factor "a₀" in their acceleration calculation; the value of a₀ is chosen such that (a) it is small enough to make no measurable difference from standard gravity in any existing observations; and (b) it can curve-fit observations of charged matter distribution to galactic rotation curves.
