Why would'nt this work?

That'll anger the universe's devs who will then bully you.

I'm not sure.
The beam of light would bend as it travels to the moon, delaying the projected dot on the moons surface. -
Sure, the time between detections is faster than the time it takes light to travel from one detector to the other. Nothing is actually traveling faster than light and no physical laws are broken.
-
this isn't at all what this example depicts, here there is actual information transfer.
this depiction is actually just false, the light would send information faster than the stick, because in the stick information only travels as fast as speed of sound in the stick, which is why completely rigid objects don't exist
-
I don't think gravitational waves traveling at the speed of light is the same as the gravitational attraction being apparently felt faster than light travels. Similarly, electric attraction between + and - charges is different from electromagnetic waves being transmitted in the field. It's not light that is "communicating" that attraction.
-
The compression on the end of the stick wouldn't travel faster than the speed of sound in the stick making it MUCH slower than light.
-
You're forgetting the speed at which the shockwave from the compression travels through the stick. I guess it's around the speed of sound in that material, which might be ~2 km/s
-
What about the speed of the earth's rotation though, could that fuck up the stick holding?
-
You'd still be limited by light speed to transmit the information between the two locations to compare times or indicate they received a signal.
-
It'll knock the moon and earth out of orbit!

With your example, nothing is “moving”.
Imagine a giant wave in the ocean that is almost lined up perfectly parallel to the shore. Imagine the angle that the wave is off by is astronomically small (0.0000000001 degrees off from parallel). Also imagine the shore line is astronomically long (millions of kilometers).
One end of the wave will crash the shore slightly before the other end of the wave at the opposite end of the shore. The difference in time between the two sides of the shore is also astronomically small (so small that not even light could reach the other end in time)
Now let me ask you: did the wave travel faster than the speed of light? Of course not. I think that is a similar analogy to the laser movement concept you described.

I'm going way way out against the standard model here.
No spacetime, no dark matter or dark energy, not even photons.
Just a '3D big ball of yarn single object universe'.If light is a 'turn of the "stick"', then gravity is how 'the "sticks" are binding the atoms together'.
And so there would not be any gravity waves.
And any measurement of them would then have nothing to do with gravity. -

That was a really good video!
