 Ok, so far so good, as it is understood that you are saying that
 if the mass of a one ton rock is multilplied by it's velocity, it
 would equal it's momentum, correct?  Then, are not you saying
 that in order for the rock to EXIST, it must possess all three
 qualities which are p, m and v?
 Please explain how so?  For if a thing does indeed EXIST, is it
 not measurable?
 SW? You always measure velocity of an object as compared to
 OK, fine, in such case as that, both objects must EXIST then,
 right?  Now comes the extra hard part of the question...if a
 thing is truly at REST, then that thing does NOT exist, right?
 Now if that thing does not exist then it cannot be measured or
 measured from, correct?  But if that thing only *seems* to be at
 rest, then any measurement you might take would be wrong, would
 it not?
 Correct and we agree on this point!
 Exactly and therefore if a thing exist, it cannot be accurately
 measured, right?  And if it does not exist, then no measurement
 is possible, correct?
 And we would agree on this point also, for light is the ONLY
 thing in the universe that has no dependence on anything else in
 the universe to EXIST, correct?  And therefore, ALL things are
 completely dependent upon their relationship to light and not
 the reverse and if light were to cease to exist, then so would
 ALL things cease to exist, right?
 There, of course, is much more to discuss here, but this is
 enough for this time as I would like to give it sum mo thought!
