An object moving near the speed of light in front of a small light source that casts a shadow on a very large, very distant object could appear to move billions of times faster than light

I’ve been pondering about responding to you. Since I can’t see this as some sort of irony - here goes.
I’m sorry, but you’re wrong. The shadow in your example would be bound by the speed of light, because the photons from the source of light are also bound by it.
A shadow is just a lack of photons on a surface surrounded by other photons.
