Bullet Cluster observations reopen dark matter debate with MOND-compatible explanation (opens in new tab)

The Bullet Cluster has so far been considered evidence of the existence of dark matter. An international team of researchers has now analyzed new data and current images from the James Webb Space Telescope (JWST). According to the team, the observations are also consistent with an alternative explanation that does not involve dark matter. If the latter is, in fact, present, it is likely to be in smaller quantities than postulated so far.
