Hi all,my second question is this.Why don't galaxies obey gravity? In our solar system the closer to our sun the planet is the faster it rotates.So the outer planet takes much longer for a solar year.
When we look at galaxies this gravitational law doesn't apply.The outside stars spin at the same rate as the inside stars.
My question is why?
