can we use a Alcubierre bubble for space communication?

There have been hints in recent news that NASA may be on the path to discovering warp bubbles that could make the local universe accessible for human exploration. NASA scientists may be close announcing they may have broken the speed of light. According to state-of-the art theory, a warp drive could cut the travel time between stars from tens of thousands of years to weeks or months.
Thats all very nice but not very practical at the moment, i cant see something as big as a space ship moving trought space yet trough a warp bubble.
But there is maybe a possibility to use this technique to transmit messages or data trough a warp bubble.
As a EM Drive might propell a crew beyond reach of standard radio transmitters in a couple of decades they will NEED a better way to communicate. So my idea is to use (if its possible) to use a (tiny) warp bubble to "transmit" data or messages trough space.
Of course we can not make a bubble yet, but thats the job of Sonny White.

Jim is correct. None of that is happening.
If it was possible to create a warp bubble, the device creating it would have to be inside the warp bubble and operating continuously to maintain it. There would be no creating tiny warp bubbles and tossing them about.
Like the age of sail, the fastest communications would be a fast ship.

I just love how certain one can be that one couldn't create a micro bubble and send a signal through it! After all, no one has remotely even created a micro bubble yet you are completely certain how it would be created or act.

We do have a good idea that some energy density would be required to maintain the warp bubble, which would have to come from some where. If you sent the device providing the energy with the bubble, it would effectively be a ship, or a probe. I wouldn't rule it out.

Based on the Alcubierre metric and what Sonny White has written about it, yes I'm certain this won't work. We're not talking about blowing soap bubbles. There's a difference between science and just making stuff up.

if one limits their imagination to how one would use a warp bubble. Then I guess I would also have to agree with Jim. But if Warp's in space-time can actually be produced and it was not possible to create a bubble independent of the device generating the distortion. Then you could still use it for communication you would just have to create a train of buoys between two solar systems constantly warping between each other. You probably wouldn't get instantaneous communication. But you would get way better than a signal propagating at light speed.
While I do not see how White's theory as currently composed could be used to do FTL signaling. If it turns out that Hoyle and Narlikar's Theory of Gravitation is proven to be a better description of what is going on in an EMDrive then it COULD be possible to leverage the advanced-retarded wave scheme used in it to do seemingly FTL Signaling.

I am aware. Thats why the first part of my response was about that work specifically. Only added the MET stuff because there are many ideas around how we COULD attain FTL transport. If MET's pan out then it is highly likely that we would be able to use the technology for FTL signaling if not using the same mechanism the universe uses for communicating inertia. Then by using the Theory as proposed by Woodward to POTENTIALLY traversable worm holes.

Okay, warp bubble communication is out of the question according to the followers here.
But nevertheless, we NEED a better communication system in space.
There are more ways to transmit information trough space. one of them is by use of Quantum Entanglement.
Would it be possible to embed a quantum entangled photon inside a single layer graphene and read the information out of a very narrow second layer parallel to the first layer? so the communication could be read without the entanglement part being affected trough the local local interaction between the two layers of graphene?

Quantum communication requires a classical communication path in parallel, which is why it can't be used for FTL comms. If your goal is just higher bandwidth, then what you are looking for is laser based communication. You can find topics on that elsewhere on this forum, because it is not new physics.

If they actually could make a small warp bubble, they would have to experiment with it to really find out what it could or couldn't do.

Warp bubbles have nothing to do with quantum communication. Read the post above the one you quoted, context is important
