Actually the speed of light is only constant locally; it is possible to violate the speed of light in space that is dilated due to the presence of mass.
If you took a super duper incredibly long stick (teacher holds up yard stick and proceeds to act out his example) that was several times longer than the diameter of the sun and put it through the exact center of the sun, that stick would appear shorter than it would if you stuck it alongside the sun. This is because the density of the sun's mass increases toward the center, and due to the dilating effect mass has on spacetime, there is literally "more space" toward the center of the sun.
