| Nov 2, 2021 at 17:50 | comment | added | m4r35n357 | It is the initial premise that I am more concerned with, as per my answer. So I should not have made the comment! I shall delete it. | |
| Nov 2, 2021 at 17:20 | comment | added | Shaggi | @m4r35n357 I'm not trying to obscure anything or get you into a mid level marketing scheme. Part of the predictive power here is experimental validation at any speed (ie. non-relativistic), without considering clocks, timing, synchronization or signal speed propagation, which would be necessary in your simplification (correct me if I'm wrong). | |
| Nov 2, 2021 at 16:20 | comment | added | m4r35n357 | How is this different from simply opening a shutter at one end of a tube for a small amount of time? Oh wait, more complicated physical measuring apparatus to obscure the analysis! | |

| Nov 2, 2021 at 9:11 | comment | added | anna v | maybe one can use your idea of interrupted light propagation in an experiment with a non rotating setup, timing a parapet interrupting the beam of light and timing when the detector sees the interruption. A thought experiment, as I have not put down numbers. Maybe at a LIGO leg. | |

| Nov 2, 2021 at 4:18 | comment | added | WillO | A perpetual motion machine requires the second law of thermodynamics to be wrong. A meaningful (i.e. not-strictly-conventional) one-way speed of light requires relativity to be wrong --- and in fact requires anything remotely like relativity to be wrong. (For the reasons why, see @AndrewSteane's fantastic answer here: physics.stackexchange.com/a/611045/4993). If one of those is wrong, my money is on the second law. | |

| Nov 2, 2021 at 0:13 | comment | added | Shaggi | Seemingly. Your line of questioning makes me think I think should add some more context/clarification, so I went ahead and did that. | |

added context and clarified question

| Nov 1, 2021 at 23:56 | comment | added | Max | But here you are only testing the speed of light in one direction? | |

| Nov 1, 2021 at 23:53 | comment | added | Shaggi | rob, great idea I did add those. I did read all the other one way speed of light questions. I don't take issue with physics not caring about c being isotropic, but generally it seems acknowledged that you cannot form a test of the speed of light in one direction, only by measuring back and forth. This seems to do it? | |
| Nov 1, 2021 at 23:51 | comment | added | Max | What exactly is your question? Your predictions seem to be correct as well as your simulation (bar modelling light as a wave / relativistic effects) - without a clock or a mirror, the "one way speed of light" idea doesn't work in this case. | |

| Nov 1, 2021 at 23:47 | comment | added | rob♦ | I didn’t understand your proposal until I watched part of the linked video. Please consider editing the post so that it’s clearer to people who can’t or won’t watch a video (by e.g. adding an image here). | |
