The discussion centers on the behavior of light in an accelerating frame, specifically within a ship, and how it appears to an onboard observer. It is established that in non-inertial frames, such as an accelerating ship, the speed of light can seem to vary due to the Doppler effect and the relativity of simultaneity. The concept of Rindler coordinates is introduced as a framework for understanding accelerated frames in special relativity. The conversation highlights the confusion surrounding the constancy of light's speed and the implications of acceleration on time dilation and simultaneity.
PREREQUISITESPhysicists, students of relativity, and anyone interested in the nuances of light behavior in non-inertial frames will benefit from this discussion.
I agree. I think you edited your post - it was shorter when I "like"d it. There are no objects following the lines of constant Rindler time, since those are spacelike. In fact, they are not lines except on the 1+1 dimensional drawing - they are 3d planes in a full 3+1 dimensional case, and are a Rindler observer's notion of "all of space, now" (which goes wrong where they cross at the Rindler horizon).JCMateri said:I no longer think the last part is correct where I said:
