- Yes.
-
- See the responses in the May 92 edition and the response to the response
- from the Authors.
-
- They were heavily criticised, but they defended themselves very well.
- The debate is quite lively and entertaining.
-
- None of the critics asked the obvious question which is: how do the
- authors propose to transfer any useful information on a single leading
- wavefront?? Surely you can only transfer one bit of data at FTL, which isn't
- too useful.
-
- If the answer is to use lots of leading wavefronts in series
- then surely you loose the FTL advantage as each wave package
- has to "wait" for the one before it to disperse.
-
- So I could not understand how the authors were proposing to
- transfer useful data at FTL rates.
-
- Does anyone have a clue?
