From New Atlas:

Some of the strongest evidence for dark matter to date has been discovered – and ironically, that's thanks to its absence. In a pair of studies published this week, astronomers have shed new light on dark matter through close observation of a galaxy previously found to have very little of the stuff, while the same team found a new example of a similar oddball galaxy.

It's generally believed that galaxies are held together through the gravitational influence of clumps of dark matter, so to find a galaxy with little to no dark matter was a surprise. And while it might sound like a strike against the theory, it actually ends up supporting it.

    And look how the dark matter proponents are misusing statistics. What they did is something like publish 100 different papers about one galaxy each, wherein they compare 90% confidence intervals to MOND predicted values for every galaxy.

    So they made 100 different comparisons and didn't adjust their significance level for that. It is actually very likely a few will be outside the 90% CI if MOND is correct. In fact, we would predict 10% of the predictions are outside the interval.
