>>11443972>>11444051>>11444057The MOND idea is that gravity doesn't work the same at slow velocities, and it can reproduce the rotation curves by adjusting parameters. It is not consistent with General Relativity, but you can add fields to General Relativity until you get something complicated enough that nobody can follow you anymore. This explanation generally fails on the Zwicky estimates, and it completely fails to account for the cosmological data.
But let's pretend they could fix that up by more parameter adjustment. There is a more direct observation of dark matter nowadays using gravitational lensing. The effect of weak lensing can be used to map out the rough distribution of gravitating matter in various astronomical situations. This process gives a distribution of dark matter which is also consistent with the main discovery methods. But not in every case. There is the bullet-cluster colliding galaxy, shown on this video, where the dark-matter distribution was completely different:

This is what people call overwhelming evidence, and it is no longer possible to deny dark matter by anyone, reputable or not. So it doesn't matter what they say, there is no more conversation necessary, the evidence is good enough to be certain, and any further denials are political, and need to be opposed politically.
