 unequivocally show that most of the galaxies rotate in direction opposite to the direction of rotation of Milky Way. This non-randomness in direction of galaxy rotation contravenes cosmological principles which requires number of galaxies rotating in one direction to be nearly the same as number of galaxies rotating in the opposite direction. The standard cosmological principle (CP) holds the view that the universe is homogenous and isotropic on large scale, i.e., universe is the same in all directions, there is no directional preference. The exact reason for the observed inconsistency is not known. Perhaps, the cosmological principle is incomplete in capturing large-scale structure of the universe and the universe began with a spin, or it has a repeating fractal pattern.){kind=link}
