Hi there Paul, and thank you for the welcome,
I understand now the precise way in which you are using the word "movement", and I'll try to make sure I adopt this use of the word in the future on this forum - it will no doubt help me express myself a little better.
I need to learn how to link to posts in other fora at some point, but the quotation from Cavediver which I found fascinating is this:
"The graviton field is what gives us the concept of distance and space-time geometry. Think about this for a minute - it is the field that defines the distances we measure between objects - whether from your nose to your right big toe, or from your nose to the quasar 3C273!"
So looking at momentum, as you have described it, let's assume that force is applied to the various matter and guage particles that constitute me (someone gives me a deserved kick up the backside) and the distance between me and, say, the door in front of me decreases.
As I understand what Cavediver is saying, what happens is not fundamentally as simple as the x. y, z and t co-ordinates of all of my matter and guage particles changing as a result of the application of the boot on my backside (though I certainly perceive a simple co-ordinate change in the 3 dimensions which I can observe) - there is something far more subtle or complex or both which is happening in the context of the graviton field.
I may be being hopelessy optimistic here, but I would love to have some sort of understanding of the momentum I experience, but in the context of that graviton field.
(And sincere apologies to the guys who use the above terms regularly and know exactly what they mean - I know I'm using them without much of a clue as to their exact meaning, but hopefully this will help people in identifying any mistakes I'm making).
Cheers :-)
