Seriously, can't the sheer speed of the inner components of a galaxy cause the gravity variance we attribute to dark matter? Wouldn't the speed increase the mass of the objects and therefore also their gravity?

- euyyn 9y agoNot that I have looked at the numbers myself, but I would think physicists would make those calculations using General Relativity, in which the effect you mention is already considered, not Newtonian Mechanics. It's a bit like this: https://xkcd.com/1758/ https://xkcd.com/1758/
- saagarjha 9y agoThe sheer speed you're talking about isn't nearly high enough for mass to change significantly. You need to get very close to the speed of light before this is the case.
