- AnimalMuppet 6y agoIt... might. But if moving masses can create moving "magnetic like" gravitational fields, then one could plausibly come up with some history of motion of conventional matter that could create the configuration of gravitational fields that we see in the bullet cluster. Can any such history result in the observed current configuration of conventional matter? I don't know. Note well: I have only a BS in physics, and have not stayed in the field. Take all opinions with a train of salt. (Yes, I stole that typo from someone here on HN. Don't remember who, but it was worth doing deliberately.)
- tilt_error 6y agoIf there are currents, there ought to be eddies as well. Where there are eddies, you usually find flotsam. Is it too far fetched that there could be regions with seemingly strange behavior, if observed individually and isolated?
- dnautics 6y agoIirc Lambda cdm fails to explain how two galaxies could wind up colliding like that in the first place, since under lambda cdm the likelihood of such collisions is vanishingly low.
