      Question for physics majors! I've asked several physicists, got unique answers each time. Let's start with object A and B. Object B is moving close to speed of light, relative to Object A. Object B is also emitting light via it's forward facing trajectory, relative to Object A.

      5) I've been told this is more of a philosophy question in the world of physics and still debated today, but I would be interested to hear if anyone has opinions and more fully understands the math behind what occurs. #physics #questions

      Iirc from physics class time slows down as you reach the speed of light, and you also expend an exponentially large amount of energy as you approach speed of light. Since all perspectives are relative time will pass quicker on objects moving faster than others

      Yes, but Speed of Light is only relative to a certain point on a plot. From the perspective of light leaving from an object moving at the speed of light, the originating point isn't moving at all, because it left at the speed of light. No center of universe. no original reference

      There is no notion of center of universe...

      My point exactly. I can be moving at the speed light relative to you, but light can also be emitting from me at the speed of light. With no center and anchoring reference, multiple reference points exist for which to measure the speed of light.

      I think the problem is reasoning about an object "moving at the speed of light." No object can move that fast.

          Replying to @TeubenRoald @KamesCG and

          If you insist on reasoning about a reference frame moving at c, then the universe collapses in the direction of travel - perfectly flat, and no time elapses. This 'viewpoint at c' doesn't make sense but that's the math (lorentz transformation)

          You can reason about object moving at 0.9999... c and it should work - obviously you cannot move at exactly c if you have mass
