If the IOR is the same on both paths then it is impossible to rejoin them. You can time the all operation. I suspect that you know that I know that light is always making a hard decision: What is the shortest path? Take it easy tricky light. 'proper time...is zero..' can imply that proper time is not ontological. I will have to think at GR speed: 43/5571=2*pi*369.2/300000 (in km/s). ;) I feel lucky today starting sexygenary ;) | |
