Unfortunately, these really nice experiments suffer from a faulty interpretation. Have you (or your professor ever heard thatthe *local* c is constant ? Because it is nothing else than a conversion factor that only decides scales. If the distant observer notices something else, then it has to do with the structure of the space-time, particularly at the tunnel effect. Ulrich |

Thank you, Ulrich for your comment.
I think there might exist different types of tunneling, there could be types (e.g. in a nucleus) where your view is right. But the Nimtz experiments are optical experiments and there i can not see any relativistic influence. If the nimtz experiment is true it is something fundamental. Lets say nimtz found einsteins tachions which now can be identified as tunneling photons. It seems that the double prism experiment of nimtz has its explanation in the macroscopic maxwell equations. There can be found a simple formula for the tunneling flux density, which make the nimtz experiment to a local theory with energy conservation everywhere. Lets say it is the completion for the Fresnel Formulas in the case of tunneling (total reflection). But the difficulty is: Nobody trusts such formulas as long the experiment is not verified by enough other experimentators. The theory is very simple and the velocities are superluminous, as nimtz measures it.

But the Nimtz experiments are optical experiments Is that with the hollow conductor optical too ? I think that the macroscopic tunnel effects well support the "relativistic" interpretation. and there i can not see any relativistic influence. The very different experiments having the same result demonstrate that nature makes no difference between different dimensions in the length. If the nimtz experiment is true it is something fundamental. Indeed. Because it demonstrates that nature obeys uniform rules, despite of common opposite assumptions and claims. You can see in http://home.t-online.de/home/Ulrich.Bruchholz/ what rules that are. (Also particles obey these rules.) Lets say nimtz found einsteins tachions which now can be identified as tunneling photons. It might be careless to define particles moving with a fundamentally impossible velocity. There are huge lots of experimental evidence for SR and its most important conclusion. GR supplies a reasonable explanation for this *seeming* contradiction from the tunnel effects. It seems that the double prism experiment of nimtz has its explanation in the macroscopic maxwell equations.

But the difficulty is: Nobody trusts such formulas as long the experiment is not verified by enough other experimentators. The theory is very simple and the velocities are superluminous, as nimtz measures it. As you could read above, one does not _need_ special theories in order to explain the *seeming* superluminal velocity at tunnel effects. :-) Nimtz measures it of course, and who has a clue of GR can understand why.
