You guys have heard of the anomalous dispersion wave?

It could be this. The wave length, phase, and velocity remain constant while there are anomalous amplitude shifts that can travel down the path faster than the rest of the wave. Weird huh?

The answer is really both yes and no. When the child at one end first pushes, yes you can run this through your slow motion camera in your brain and can see the warp of the board at one end as the pulse travels across the teeter totter board all the way to the other end. But, then once the board is in motion the other side is also in motion. As long as the one child continues to push down the other side continues to go up and thus you have a subtle signal that continues to travel instantly from one side to the other as long as there is no change of state -- one child continues to push down and the other child continues to go up. This is an instantaneous conditional state only. If the one child then ceases to push down, again you can run the slow motion camera in your mind to see the slight warping of the board as the pulse to stop once again travels down the board to change directions on the other side.

Just like the anomalous group dispersion, you can have single state faster than light responsive states, but you cannot have faster than light reactions to changes of states.

JDLaw's New Laws of Light Speed
1. The observed speed of light in any reference frame is approximately 299,792,458 meters per second.
2. No mass, energy, or quantum particle can be observed directly by another mass energy or quantum particle that has a greater relative difference in velocity than 299,792,458 meters per second.
3. Where two masses, energies, or quantum particles are moving, spinning, or vibrating with velocities separated by greater than 299,792,458 meters per second relative to each other they must exist in a different quantum realities. However, a third mass, energy or quantum particle whose relative velocity is between the two may observe them both.
4. This duality is finite, but the number of dualities is infinite.
5. There is another reference frame in some reality that exists somewhere or sometime where this reference frame, you are in right now, is moving at the speed of light relative to that other reference frame.

LOL. I like how you split a post into 4 separate posts to get your point count up.

Actually, I think that in the see saw case, the propagation that goes from one end to the other is still limited to the speed of light. After all, it is effectively transmitted molecule to molecule by the electromagnetic force, which propagates at c. The other end can never exceed c even if the fulcrum is offset to give a magnification effect.

Group velocity is akin to the point where two scissor blades meet if they are moving toward each other and can exceed c, but not in the sense of transmitting information.

Or so says conventional physics. As you know, I believe that limit will ultimately be broken. This may be the first chink in the armor.
