Hello, Recent observations claims that Dark Energy is effecting the expansion of universe and increasing the anisotropy in the cosmic microwave background (CMB). Do you agree?? what about cosmic magnetic field and its effects on the expansion and CMB ? If it is increasing the anisotropy or not? Also the rule of cosmic string is to enhance the anisotropy in CMB? Can we say that these three are accelerating the expansion and increasing the anisotropy.?
