B One way speed of light in one reference frame measurement

AI Thread Summary
The discussion centers on the challenge of measuring the one-way speed of light using two synchronized clocks placed 100 kilometers apart. The proposed experiment involves sending light pulses to synchronize the clocks and then measuring the time taken for a light signal to travel from A to B. A key point raised is that any measurement of one-way speed relies on a synchronization convention, which inherently assumes the isotropy of light. The participants highlight that without a universally accepted method for synchronization, the results are inconclusive. Ultimately, the conversation underscores the fundamental difficulties in measuring one-way light speed without making assumptions about its properties.

Two clocks with photo detectors are 100 kilometers apart at A and B. On the center of AB axis two light pulses are sent to the clocks , synchronizing them. Then a light signal is sent from A to B. The two stationary observers record the time from event at A to event at B. Is there a one way speed of light conundrum in this experimental setup ?

Unlike the above references my experimental setup does not include roundtrips of light signals . And furthermore as long as the speed of light is isotropic it would not be necessary to know it's speed synchronizing the two clocks.

Obviously this procedure only synchronizes the clocks if the one way speed of light is isotropic. So you are assuming your conclusion.

There is no possible experiment and no clever setup that can possibly measure a one way speed of anything without some synchronization convention. That convention determines the result.
 
Could atomic clocks at A and B photo detectors that are started from signal at center of AB axis determine if the speed is isotropic ? The clocks are started at t1 . Then if both clocks at any t2 have recorded the same elapsed time then it seems by construction isotropy can be determined. Ok I see the problem with this : how do both A and B agree on t2

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
