As I understand it, anything that is travelling at the speed of light moves through space but not through time. So if we were able to track a photon from the surface of the Sun, we would say it took about 8 minutes for the photon to travel to Earth. However from the photon's point of view, it reaches the earth at exactly the same time it left the Sun's surface, as there would have been no movement in time. Therefore, if nothing else is moving through time, I would guess that means from the Photon's point of view, nothing else can be moving through space either. So in the above example, the Sun and the Earth are in the exact same relative position in space and time during the 8 minute journey from when the photon leaves the Sun until it reaches the Earth and is absorbed. I would therefore assume that if this is true then the same can be said for light travelling to Earth from any star or source. So for a photon travelling to Earth from a star that is say 10 light years away, (ignoring gravitational lensing) during the 10 year journey nothing would be moving in space relative to the photon and it would arrive at a detector on Earth at the exact same time it left the star and, both the Earth and the distant star would be in the exact same relative postion. Is all this correct?
