Relativity -- problem of simultaneity I wrote a basic outline of relativity on my blog. I think I got it right, as far as it goes: wp.me/p2ukOd-D --As I understand it, relativity says there is no *preferred* sequencing of events. Two events can be considered to be simultaneous, or one can be considered to happen before the other, or vice versa, depending on your frame of reference. The more I thought about this, the more I wondered: Can't the time distance between the event and the beginning of the Universe be measured objectively? Does that not make room for a notionally objective observational frame of reference, albeit one no human observer could occupy? Or have I just misunderstood the implications of the theory of relativity? Conrad.
