Quote: "The stars in the Wild Duck Cluster, it turns out, are spread out in the color spectrum not because of different ages, but because of different rotational periods".
Fast spinning stars seem to be bluer !
I just realized that it means that even here the speed of light of a spinning star is faster at the upcoming side of the star, ( is bluer) than at the other side (is redder) which is dominated by the blue shifted side just like the O'Connell effect of binary stars tell us.

The New Physics
Quantum FFF Model: 1: The lightspeed is only local the same. 2: Black holes
absorb only smaller BHs they repel all Fermions, they have NO inertia. 3: BHs have real hard hairs, in the form of
two or even more plasma jets, ejecting all the plasma swirling around the BH
not able to enter the BH by BH repeller effect. 4: Dark Matter is the same as
BHs 5: Dark Energy is only a part of Quantum Gravity. from space around
graviton radiating Fermion mass. 6: The Higgs knot is the smallest Dark Matter
Black Hole. 7: Dual Herbig Haro Hotspots are dual black holes pushed away by
jets, with star forming (pressure cooker effect) in the middle. See: http://vixra.org/author/leo_vuyk
