What is movement and velocity ?

Hi there all - I'm a new member of EVC - and a large part of the reason I joined was to learn more about this pretty fascinating place in which we live.I was reading some of Cavediver's posts about how our universe is comprised of a number of overlapping fields (possibly aspects of one overall field), and that subatomic particles are excitations within those fields at any one point.What was particularly fascinating was Cavediver's explanation that one field's excitations represented what we perceive as distance. Would it be possible for someone to try to answer for me (an intelligent non-scientist) the following questions:1. In the context of that explanation of fields, how would all of the various sub-atomic field excitations that make up me (or anything else), moving from what I perceive to be one place to another, be expressed ?2. How would the expression (in that context) of that movement differ, dependent upon my velocity (in my perceived 3 dimensional terms) ?3. And moving on from there, (and given what we know about my velocity in space time being C) how is velocity (in 3 dimensional terms) at closer to C (or in a photon's case, at C) expressed in those terms ? In other words, what is the relationship between these fields and time ? (If time can be treated as separate in this context).These are questions which I think I need to answer, to try to help my understanding of this.And just as likely, I may need to know why these are ignorant questions, to try to help my understanding of this ;-)Edited by vimesey, : No reason given.

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 :-)
