Why would'nt this work?

Dang there goes my patent

Think of it like this. If our universe is a simulation, then the speed of light is the maximum speed at which information can propagate through reality. We know that for anything to move through space, it must move from one adjoining position to another, then another, then another, incrementally. Each one of those increments takes, at minimum, one 'tick' of the universe. That's one tick to increment each bit of information, that is, the position of something moving at light speed from position x,y,z to x+1,y,z. Light moves as fast as the universe allows; if there was a faster speed, light would be doing it, but it turns out that our universe's clock speed only supports speeds of up to 299,792,458 meters per second.
What you have here is sound. Motion propagates through material, at its fastest, at the speed of sound in that material. That's part of the reason why moving large scale objects quickly gets weird.

I used wave function as a bad form of shorthand for the general properties of the photon, such as the theoretically infinitely extending magnetic and electric fields. Those associated fields stop existing when the photon is absorbed onto a screen. They collapse faster than light can travel. This doesn't ruin much of modern theories, because there doesn't seem to be a way to transfer usable information through this phenomenon.

Best answer

What about the mass of that stick? Inertial doesn't care for your little silly games.
-
It depends on the person who's holding it and pushing it. For me it takes at least three minutes!
-
I don't see this mentioned in any of the other comments: the repulsion between atoms that causes the movement to propagate through the stick is actually communicated via photons. So your push really generates the same kind of particles that your light torch is generating, and they travel at the same speed (except slowed down by repeated absorption and excitation by the electrons in the atoms of the stick).

That's wack af
-
Neither do the two gravity wells the stick spans. And the earth and moon are moving relative to each other, someone would probably get their head knocked off by that stick. Before it eventually falls to the earth with quite a bit of force because earth's gravity well will win. Then it'll eventually settle into a giant teeter totter, assuming it is rigid enough to survive the impact.
-
Putting it on the moon is just a distraction. It doesn't matter if the rod is 1m long or 100,000km.

because...

Alas, the longer the stick is, the floppier it gets.
-
I don't get it. Care to explain?
-
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
