Hi Neutralino ... Firstly, I only posted this thread as a bit of fun. And as such, I posted it in the 'Brainstorming' forum. Unfortunately only paid members can post in this area of ToeQuest. So Robert moved it for me so that it would be available to all.

Perhaps I could put a plug in for Robert here. Paid membership does not cost much, Servers and associated hardware cost money, so does the EMF force that drives them. A nice Chrissy present for Robert would be if paid membership increased....

This is commonly known as the relativity of simultaneity. It's also why we rarely discuss global time, but instead assign light cones to each point in space.

The Relativity of Simultaneity as you say, implies that an observer will see things in the past (underlined above) and conversely ??? Which reduces to the fact that the past, present and future, since they can be observed from a single 'moment exist simultaneously.

I agree that the 'Moment' is the sticking point. How to define a Moment ??

This was meant more as a 'what if' point of view. A brainstorming exercise. The fact that our arm, in the action of swinging a baseball or cricket bat is now in different motion in relation to our torso, in relation to our brain. This must also be governed by GR.

Actually, I added this (parrallel universes) to the original post as an aside. But Austin, astute as ever, picked it up and elevated it to the credible .....
