In this video, I do an in-depth explanation of the relationship between light and Special Relativity. When I pitched "The Light Compass" in my last video, a lot of people were skeptical because they thought that the rules of SR prohibit the compass from working.

As I cover a lot of math in this video, and the process can be hard to follow, I have written a companion article where you can go through it there as well:   / chapter-5-addl-understanding-the-holes-in-...  

As a note, I am working to have written companions articles for all my videos, but currently still working through the backlog. If you are new to Special Relativity, or unfamiliar with the issues I am trying to resolve, I recommend watching the previous video (   • Chapter 5: What is Time? Special Rela...  ) and exploring the additional education resources in that video's description. This is NOT an education video on the current accepted science of Special Relativity, but it builds upon that to propose alternative interpretations and ideas.

MISTAKES AND ERRORS:
My dyslexic brain made an obvious mistake at the beginning of the whole math segment. The first calculation should be L = ( c - v ) * t NOT L = ( c - v ) / t. Also, again when I computer the rate of return of the photon later, the equation should be V(photon/mirror) = (c + v) *t NOT (c+v) / t. The outcome is the same since t is 1, but wanted to make sure I noted that.

Also, leaving such a dumb mistake in the walkthrough kinda helps me know which critics actually watched the math segment since it is such a glaring point to pick on.

IMPORTANT NOTES: It is critical to acknowledge that the independent reference frame of light I am assuming is a consequence of “c” not light. It is the limit imposed by “c” as a dimension that creates the independent frame. If light is “slowed down” in a medium, that independent frame is changed and has to incorporate the inertial frame of the medium.

This distinction has implications for the conditions by which we have to test this proposal. It can only be confirmed by measuring photons in a vacuum, unimpeded by any medium. I wish I thought of this phrasing before finishing the video, but part of this process is getting feedback and finding out what's unclear.

Finally, the "spaceship" mental experiment assumes a condition of "perfect observation" where a photon is not having to actually travel to Bob for him to observe it. Putting all those caveats in the explanation seemed tedious and ultimately distracting. My assumption is that the majority of viewers can understand the nature of the exercise. "Simultaneity of Events" doesn't change the point, it just kicks the can down the road.

THANK YOU: For all the thinkers and engineers out there recommending ideas to make The Light Compass work, I am excited it has inspired you. The overall feedback is that this is an incredible challenging experiment to run, but certainly possible.
