DanMP Posted February 15, 2016 Author Posted February 15, 2016 I still don't understand why it should be a shift. How you explain rotational frame dragging if the frame that rotates doesn't travel with the Earth. (This is not an argument in my theory!) Nobody replied to this. If there is no total linear frame dragging, rotational frame dragging should be considered just a (tiny) deformation of the space-time while the rotating massive object is passing through it. The instrument that measured it traveled with the Earth, so it was able to measure the rotation/deformation only for a tiny moment ...
swansont Posted February 15, 2016 Posted February 15, 2016 I still don't understand why it should be a shift. At one point, there is frame dragging, so you have frequency w. At some other point, it "turns off" and you have none. The frequency must be w'. YOU said there is no gradual transition. How can there not be a shift?

If you talk about redshift/blueshift of incoming electromagnetic radiations, there is no problem, no difference. We will have exactly the same shift. The shift occurs at the co-moving border and it is the same as if it ocurred at the observer on Earth. Nothing is changed in between. -1

How can you say there's a shift at the border, but nothing has changed? How could you detect the shift?
DanMP Posted February 17, 2016 Author Posted February 17, 2016 How can you say there's a shift at the border, but nothing has changed? Nothing changes between the "border" and the surface of the Earth. No more/less shift. How could you detect the shift? Using spectroscopic measurements, as usual.
swansont Posted February 17, 2016 Posted February 17, 2016 Nothing changes between the "border" and the surface of the Earth. No more/less shift. That's not the point. There is a shift as you cross the border. Why don't we observe this with communication with remote satellites?
