Wormhole FTL communication

>excerpt<
If wormholes are possible, then ordinary subluminal methods of communication could be sent through them to achieve superluminal transmission speeds. Considering the immense energy that current theories suggest would be required to open a wormhole large enough to pass spacecraft through it may be that only atomic-scale wormholes would be practical to build, limiting their use solely to information transmission. Some theories of wormhole formation would prevent them from ever becoming "timeholes", allowing superluminal communication without the additional complication of allowing communication with the past.[citation needed]

The microscopic causality postulate of axiomatic quantum field theory implies the impossibility of superluminal communication using phenomena whose behavior can be described by orthodox quantum field theory.[2] A special case of this is the no-communication theorem, which prevents communication using the quantum entanglement of a composite system shared between two spacelike-separated observers.

Some authors have pointed out that using the no-communication theorem to deduce the impossibility of superluminal communication is circular, since the no-communication theorem assumes to start with that the system is a composite system.[3] However, these authors do not address the proofs of the impossibility of superluminal communication which depend on the microcausality postulate rather than on the no-communication theorem.

I believe there are several textev assertions that the only way to communicate through a wormhole is by traveling through the wormhole.

Since the idea has been around for a bit over 2,000 years in the Honorverse, I'd assume that converting the Theory (aka unfounded speculation) into practice has proven unfeasible. The in universe textev of the FTL communications they have (finally) developed suggests that FTL communications aren't having any obvious effect on Honorverse civilization.

It might, someday, be economical to set up the "wormhole barges" someone suggested in the economics thread to relay news business and banking information through wormholes, but until the set up FTL relays over interstellar distances, and/or learn to generate wormholes on demand, communications away from wormhole termini are going to be as slow and sluggish as they are now.

No, it denotes politeness -- ie not saying people will make day trips to the surface of the sun to sunbathe nude first.

In the Honorverse, the only way to send something through a wormhole is with a hyperspace generator. In other words, the only way to communicate through a wormhole is to send a ship through. And that's how the Honorverse currently does it. Messages are sent through wormholes on ships.

Thanks for the intelligent reply E. There is that. And admittedly, I don't know how they differ.
