I'm sorry, but this sort of comment shows that your grasp of relativity theory is about as good as your understanding of block universes - which is to say that yet again, you're completely missing the point. All frames are equal when it comes to representing physical facts, some are just more convenient than others for doing the maths (hence "relativity"). And you can't make Alice's age whatever you like, you can only obtain different values by measuring it from frames moving at different velocities, because the planes of simultaneity attached to those frames intersect Alice's worldline at different points in space-time. Why not go away and read up on the subject before you pontificate about it? -- You received this message because you are subscribed to the Google Groups "Everything List" group.
