Comments by "Jeff Huffman" (@tejing2001) on "Why No One Has Measured The Speed Of Light" video.

The best definition I've seen of the word "reality" is this: "reality is what you run into when you're wrong." What I love about it is that it points out something that I think is important to this discussion: if you can't be wrong about something, then it's not real. Throughout this video, you keep talking as though there is an answer to what the "one way speed of light" is, but we just don't know it. But why do you even think there is an answer? If there is no experiment that could measure it, then it's not a property of physical reality, just our model of it. To make the issue clearer, consider the same argument that was used in regard to simultaneity here applied to what it means for 2 points to be at the same height in different places (ignoring for now the curvature of the earth's surface and gravitational field). What if "horizontal" is actually different than we think? What if objects to the north are actually higher than we think they are, and the ones to the south are lower? What is the real "slope of horizontalness", and how could you possibly measure it?

@raffaeledivora9517 When it comes to quantum physics, I also subscribe to the "give up realism, not locality" concept, especially since on reflection, giving up realism isn't as bad as it seems. What you're really giving up is definiteness (the idea that there is always, in principle, an answer), but you're not actually giving up coherence (the idea that if we have incompatible knowledge, one of us is wrong), which is all you truly needed for the intuitive notion that "reality is real".
