it is a common mistake to assume that a relatively moving body has just one ‘velocity’ whereas, in fact it has two.
Let's review this and see if we can distinguish the substance from the semantics.
In the propagation of light from the sun, from the viewpoint of the light, its proper time, it passes from one point to the other without duration; whereas from the viewpoint of the observer, this process takes 8 minutes and change.
On the other hand, in a quantum event as classically described, there is information moving from one place to another, or a relationship between the two places which exists and then collapses, which is a linear sequence and therefore must have a duration element; but from the viewpoint of the
observer it seems to take no time at all. Proper time and relative duration seem to be
reversed in this instance.
Why does this happen? Or doesn't it?
