A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.

The shadow has no FTL information here. Watch https://youtu.be/JTvcpdfGUtQ
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.
That's the point yes
And the edge of a ball of light created by a powerful spotlight could do exactly the same thing. That video is nothing but sleight of hand style tricks dressed up as the speed of dark. You can recreate every scenario using light to argue light is faster than the speed of light. What you're doing isn't movement at all, period.
Imagine earth has a ring around it the distance of the moon. You have a powerful laser pointer and rotate 360 degrees while pointing at it. The dot of light "travels" around it at insane speeds. This is what the video argues "dark" or the shadow is doing. But if you think about it for a moment you realise each "dot", whether it's the shadow or the laser pointer, is actually a unique thing, and nothing is actually "moving" at all. Shadows don't move. Ever. They aren't even something. They are just light being blocked.
Congrats you get it
