Transmittions Faster then the Speed of Light

Does anyone have any updated information from the experiments in Europe
that seemed to suggest that they had been able to transmit information
faster then the speed of light. I believe that it was in Germany and that
they had encoded music into the test stream and were able to decode it at
the receiver.

Was that a case of misreading the results or did it actually happen?

If it did happen, would a transmission of that type be detectable over a
long distance?

That sounds like old news Ed. I remember there was a German
researcher doing that lind of stuff maybe a few years ago
(he may have improved his experiment, but...). At that time,
while he seemed to be transmitting music "information"
faster than c, the general consensus was (still is) that it
is really not, the explanation lying in the exact technical
definition of info, and his music signal essentially not
being the entire signal curve or waveform (this is a vast
simplification and I was never a real expert on this stuff.)

Just did a quick google search on web sites with "ftl
experiment"
and found one particular reference with other references.
see:

http://www.aei-potsdam.mpg.de/~mpoes...k/FTL/tunnelin
gftl.html

The following is a quote from there on the type of
experiment I remember (and which others have also done.)

"So, has special relativity been disproved, now that FTL
speeds have been measured? The first problem with this naive
conclusion is that, while in special relativity neither
information nor energy are allowed to be transmitted faster
than light, but that certain velocities in connection with
the phenomena of wave transmission may well excede light
speed. For instance, the phase velocity of a wave or the
group velocity of a wave packet are not in principle
restricted below light speed. The speed connected with wave
phenomena that, according to special relativity, must never
exceed light speed, is the front velocity of the wave or
wave packet, which roughly can be seen as the speed of the
first little stirring that tells an observer "Hey, there's a
wave coming". Detailled examinations of the differences
between the velocities useful to describe waves can be found
in the classic book

Brillouin, L. 1960 Wave Propagation and Group Velocity. NY:
Academic Press."

Actually, discussions of this sort of expt. are still always
found on the sci.physics newsgroup (usenet.) They usually
end up with those insisting the expt. works being called
"cranks" or "trolls" by the real physicists there. )
