Your relative speed makes a difference. If you are moving away from the beam source then the laser will to you have less energy. If moving away at extreme speed the beam will have so little energy that you might not be able to detect it.davidjoe said:not to try to answer my own queries but I think the answer under relativity is that I don’t have more time inside the ship, as a result of how fast or slow I may have propelled it relative to the laser. It’s tough to wrap my mind around that because an inch a day slower than C, or a micron a millennium slower than C, are both less than C, it means I’d see the laser pass me at C as if I am not moving relative to it, at all. For that matter I think if I were to pass it in the opposite direction a micron a year under C, same result. This really wasn’t the question I was wondering about originally but it (SR GR) has a certain way about it, of becoming the analysis.
A cartooned steam train with a lantern by a pedestrian with a lantern is sure easier for me to take at face value.
