At first I claimed shadows and beams could travel faster than light. For some reason this enraged you, despite your agreeing with me.
Look who is enraged. You said you could move
information faster than the speed of light, and you do not envision what you said, not even now.
You have not even seen that your claims have a reach that goes far beyond your wildest imagination because you have decided to be, and continue being, ignorant about General Relativity. For starters, you have not yet accepted that your claim implies that either General Relativity is totally wrong in a simple, everyday scenario or that information can travel time backwards.
Let me help you with this elemental Relativity problem that you have not been able to research for yourself. The segment of light that came from your laser beam a nanosecond ago is positioned and pointed in a straight line from where the laser
was a nanosecond ago. If you could take a picture that was that fast, you would see that the light from a nanosecond ago has moved a foot from the laser, and is moving away from the place the laser was then, not now. The laser beam is not moved like a whip. Each little segment of the laser beam complies with Relativity, as everything else we know in the universe (at least until now, and maybe some subatomic particles).
If you want to see a simpler experiment, play with a garden hose. The water moves according to where the hose was when the water left the hose. The whole column of water does not move like a solid stick.
The shadow works just as the laser beam does. This is simple wave theory, where the maximums and minimums of a wave both act as waves should.
Now, you can get me any scientific paper where you see information moving faster than light and we can carry this discussion. Otherwise, rant a little more and delude yourself about your Physics knowledge. I will not reply.
