a) space and time can no longer be thought of as seperate entities, and it is far more accurate to combine the two into a space-time

b) there is no fixed point in space, ergo, no fixed point in space time

c) it is reasonable to suggest, then, that each moment of 'time' - now spacetime, should be able to be co-ordinated as a point in space and a point in time, albeit one that is moving

my question is this; if we know the speed and distance that has passed between two points in spacetime, and presuming one can break the cosmic speed limit, if we used the co-ordinates of a point in space and time, would we find that moment in time?

further points -

d) an outside observer at some distance could be observing the french revolution as though that were the present, of course if they set out to visit byt the time they got here that would be the past. is it that we could only observe the co-ordinates and never visit, even breaking the cosmic speed limit?

e) if we can visit those co-ordinates, why do satellites not show a continual stream of moments in time and space?

hope that makes sense
