File under "Credit Where Credit Is Due"
Ethan has been an up-front adversary on the question of the Copernican Principle and geocentrism generally on his blog- it is very nice to see him pulling the covers on a recent shameful claim of the "detection of evidence for dark matter", which was nothing of the kind.
To reiterate, based on what AMS has presented, there is nothing to suggest that they have detected any evidence whatsoever for particle dark matter. The press release (and the earlier press conference) — reported upon by many that I will not link to — suggest otherwise, and that is misleading. In fact, calling it misleading is generous, because I personally believe it is deceitful, and it’s a deceit that I even anticipated a few weeks ago!
