Thanks for your thoughtful reply, Mike.
You’re absolutely right. Special relativity doesn’t depend on perception. The reason I mentioned perception was because of its importance in Buddhism. If we understand (a) ethics, (b) immersion, and (c) wisdom as a summary of the path, perception pertains to each component, e.g. (a) looking for the good in other persons (ethics), (b) experiencing the absorptions (immersion) and (c) perceiving the world as non-self (wisdom).
With the “relativity of perception” I meant the following. In a hypothetical “speed of light = 1 m/s” world like in the video, a stationary person would perceive the desert, sky, and building very differently from someone traveling close to 1 m/s due to relativistic effects. A significant difference between walking and standing still!
I think this is interesting and worth sharing in a Buddhist context because it’s a perfectly secular example of the variability—and therefore broadness—of perception; much broader than might be inferred from ordinary non-meditation, non-drug/trauma/near-death induced experience. And this notion that consciousness is vast might inspire its exploration by way of meditation. Needless to say, there are other examples, some of them unique to consciousness.
