@El_Machinae exactly. the speed of light is constant everywhere.
@Ziggy_Stardust Light always travels in a straight line. However, if space-time is curved, we perceive light as traveling on a curve. the event horizon is the place where space-time is curved so much that the "straight" path light is traveling is perceived as a spiral ending in the center of the black hole.
Sin version a) would have an event horizon much closer to the center of a black hole, which would be a terrific opportunity to examine these cosmic enigmas.
