    Ok I watched the video and I get that no information is travelling FTL. “Speed of darkness” is misleading tho, because the light at the shadow’s edge has the same “speed” as the shadow.

      The edge of the shadow can move across the surface of an object an essentially infinite speed. That’s the speed of dark

        Yeah I get it. Do you get that the light around the shadow, that isn’t part of the shadow, is moving at the same “speed” - so it’s not the speed of “dark”. It could be dark, it could be red light, blue light, full white, any color or lack of color.
