“Counterclockwise rotation” refers to a variant in which the transition is “early,” occurring at or before lead V 3, whereas “clockwise rotation” is a variant in which the transition ...

might have influenced the rotation dynamics of galaxies, creating the observed clockwise-counterclockwise asymmetry,” Nikodem Poplawski, a theoretical physicist at the University of New Haven ...

About half of all spiral galaxies appear to be rotating clockwise and the other half ... spin with their arms trailing the direction of rotation. This is what we expect from our models.
