“We don’t know what dark matter is or how to directly measure it but this distant galaxy has none”

> DF2 has consistently been portrayed as fatal for MOND despite consistently being shown not to be a problem. I’ve given up writing formal papers showing this, as nobody cares. They just hear what they want to hear, which is that MOND is wrong. Indeed, after the 2018& incident I swore off doing so.
This should set off crank alarms when you read it.

According to MOND theorists, a dwarf galaxy like DF9 doesn't prove dark matter, since it's sitting in the gravitational field of a big neighboring galaxy (NGC 1052) and thus its boost is suppressed. They call this the "external field effect".
