Hi. I probably can find this answer in your posts but my time online is somewhat limited. I thought of something this morning that I've waited all day to ask. OK. If two light-emiting objects (stars?) are moving towards each other at a speed greater than light, does the light take on new properties? And, would time be affected? (The reason I ask is because I recently learned that if they're moving apart faster than the speed of light, they will not see each other.) Thanks.
