In summary, this could be an effective way of communicating information between two places that are far apart.

OK, just had a thought. And I would be grateful if someone could explain why this couldn't work:Place A is on a surface

Place B in on the same surface but, say 10,000 miles away from Place A. Therefore communication between them is limited the speed of light .

But what if, at Place A there was a laser constantly projecting a beam to Place C - which for arguments' sake is 1000 miles above the surface and equal distance between Places A and B.

The laser's beam is by default fixed onto Place C Box 1, but at a time of asking the laser is quickly moved to shine on Place C Box 2. At this point a similar such laser which contently fires from Place C Box 2, then moves very quickly from shining at Place B box 1 (back down on the surface) to Place B Box 2

In effect, Place A has "informed" Place B of a change in status quicker than the time it takes light to travel in-between Places A and B in a conventional method, as the lasers were already on and shining, they just needed their angle adjusting a fraction.

This is based on the principle that lights and shadows can of course cross a distant object faster than the speed of light without violating Relativity.

If the lasers I quoted were always on, and just needed to move slightly, and the boxes be automated to do something when light hits them, could this then = de facto FTL communication?

When the laser at A is shifted, the effect will not be seen at place C until a speed of light delay has elapsed. Place C, box 1 will remain illuminated for some time (about 26 milliseconds in this case) while light sent earlier from point A is still coming in, even though the laser at point A is already pointing at box 2.

Of course!

Thank you!

I'll put my Nobel prize celebrations on hold for a while
 

Related to Exploring a Theory for FTL Communication

What is FTL communication?

FTL communication, or faster-than-light communication, is a hypothetical method of transmitting information or signals faster than the speed of light. It is currently not possible according to our current understanding of physics.

Why is FTL communication important?

FTL communication is important because it could potentially revolutionize the way we communicate and send information. It would allow for near-instantaneous communication across vast distances, making space exploration and interstellar travel more feasible.

What are some theories for FTL communication?

There are several theories for FTL communication, including the Alcubierre drive, wormholes, and quantum entanglement. These theories propose ways to bypass the speed of light limit by manipulating space-time or utilizing quantum mechanics.

Has FTL communication been proven to exist?

No, FTL communication has not been proven to exist. While there have been experiments and studies on the possibility of FTL communication, none have been successful in demonstrating its existence.

What are the potential implications of FTL communication?

If FTL communication were to be proven possible, it could have significant implications for space exploration, communication, and technology. It could also challenge our current understanding of physics and lead to new discoveries and advancements.
