Title: Is there a connection between slow motion filming and time dilation?
Post by: geordief on 29/03/2024 13:42:32

This seems like such an obvious question that I am surprised it is the first time it has occurred to me .

When we speed up the recording of a film and play it back at a slower speed we see everything slowed down.

Again , if an object is in relative motion to our frame of reference we "see" things slowed down  in it (as in the twin astronauts scenario and others)

If we speed up the recording of the film to the maximum the speed of the replay goes to zero.(with no loss of detail)

Is this just an analogy for time dilation or is this more or less how time dilation actually works?

(I realize ,I think that the doppler effect plays no part in slow motion filming but I am not concerned with it for this question.)

This link might be an interesting read...

I do Not wish to take this Off-Topic atall.
But Time Dilation should be renamed as Time Differentiation.
(SoLiaV remains Constant for All)
