    Default MACHOs ruled out over huge mass range



    in another recent thread about new DM dwarf galaxies around the MW there was a promise of a result out today.

    newly discovered MW satellite galaxies shed light on Dark Matter

    today's result is so important it deserves its own thread rather than a mere update though. essentially MACHOs as DM candidates are now ruled out from 10^(-7) solar masses up as a result.

    How a Star Cluster Ruled Out MACHOs

    this doesn't mean that SOME of the DM mass can't be in MACHOs, but it pretty well makes it impossible that all DM could be MACHOs.

    so DM might be MACHOs and Cheese?

    If the result is that important, might not verification from other groups and techniques be in order?

    The result fits with findings already accomplished by other groups.

    So the suggestion

    is already accomplished. More is fine and certainly will be done but it is not reasonable to expect or hope for reversal of this result.

    Well the conclusions from the 2nd link in nFA's post seem to definitively rule out primordial BH's as constituting the bulk of DM's mass. I'm finally satisfied with the conclusion, disappointed, but satisfied.

    It's not me. Really!! It's Mom Nature the original crusher of hopeful dreams for as long as there's been hopeful dreams.

    I'm just old enough to have figured that out. Crushed dreams are excellent teachers. The only way to avoid crushed dreams is death. So I prefer continuing dream crushing!
