Shouldn't gravitational friction from dark matter slow the MCs down enough that they won't escape?

- ben_w 3y agoGiven dark matter isn't yet well characterised, there definitely isn't a "should" in what we know. But I'd be surprised, because if it was even a possibility that it might be able to apply a friction force large enough to be relevant to to the relative motion of the galaxies, I think a lot of people would be talking about this in the same breath as the bullet cluster.
