Jesse, Yes, but what you are saying here is just that it is impossible to unambiguously OBSERVE that the proper ages are the same. I agree. But it is possible to unambiguously DEDUCE and CALCULATE that they MUST be the same, which is all my theory says. If we can use calculation and deduction

Bruno, Your contention that there is no evidence for a universe is simply delusional. The very fact you can make any statement absolutely PROVES a universe of some kind. Your contention is so absurd it's laughable.. Edgar On Friday, February 28, 2014 10:14:29 AM UTC-5, Bruno Marchal wrote:

Jesse, With regards to your contention in your first paragraph below it may express the correct view of frame DEPENDENT simultaneity, but that is NOT the point I'm making. I'll try to explain more clearly. This example is revised to attempt to conform with your previous objections so please
