Faster than light (superluminal)

NOT

I enjoyed learning this cosmology example and great explanation.


Superluminal Speeds (faster than light) - Sixty Symbols
Sixty Symbols


So a question that arises out of this is:

at 5:47 in the video he gives an example of the moon.

Because the light trail is moving faster than light on the surface of the moon, could we see the pixelation and it would be more pixelated the faster than light it went?

I don't think so, unless it is only single photons arriving at each point, which would then be discrete dots of light on the moon's surface, separated by the wavelength of the light used to sweep the moon. Pretty unobservable, I would think...
