Does local spin make a difference in relativity?
Recovered historical discussion from Does local spin make a difference in relativity?.
I was thinking about a distant object moving from point A to point B at the speed of light but keeping a constant distance away from the observer.
Could the observe observe them moving faster than light? How is that object limited by SRs "nothing can travel faster than the speed of light"?
The thing is what if the observer was rotating slowly to coinside with the object so that the object didnt appear to move with respect ot the rotating observer?
Observer is rotating at the same rate that object is travelling in the direction of the V ( downwards ).
0--------------------------------------------------------V
For the observer it would appear that the object is not moving at all, even though it is travelling through space at the speed of light.
For the observer all of the other stars and everything else around ti would be moving at apparently the speed of light ( but this is really just because the observer is rotating ) .
Does this make sense? If not I can try to draw a picture.
