Hi Dr. David Boboltz,
Thank you for coming to the forum, it's a rare privilege for a member of the public to communicate with a professional scientist.
I learned from reading these forums that light speed can only be measured involving a two-way round trip. The problem is that you cannot guarantee to synchronise two clocks, one for each end of the experiment. If you synchronise two clocks next to each other and then move them apart, the movement and acceleration, according to relativity, will alter the timing. Synchronising the clocks in the middle of the experiment and moving each one an equal distance to each end still does not guarantee the clocks have not been moving in opposite directions through a flowing ether. For similar reasons you can't connect a cable between the clocks and synchronise them either because once again you can't guarantee the electricity will flow at the same speed in opposite directions.
When someone says you can't do something it gets me thinking. I came up with the following thought experiment and I would like your opinion on it, please.
What if you have a mechanical clock with a rotating dial floating in space connected to another dial with a very long shaft, say one kilometre or even 10 kilometres long. Would this mean each end of the shaft is exactly synchronised? If so, all you have to do now is shine a laser beam from one dial to the other and record the time it takes for a one-way trip, job done? You could then rotate the shaft 90 degrees to measure the speed in another direction just to check if there is a flowing ether. Also instead of a dial, you could have slits in a disc as in some of the original experiments used to measure the speed of light.
Also, you could have one end of the shaft nearer a strong gravitational body where time is supposed to slow down so what happens to the other end of the shaft?
Yet again you could also spin one end of the shaft around the other and the different velocities again should produce different times, so what happens to each end of the shaft in that case?
I know next to nothing about relativity, so you may either laugh or be unable to answer it, I'm not sure which.
Thank you
