How is it possible that there are so many retarded people who think "radio waves" are sound?
Radio waves are electromagnetic radiation... aka they are just a different frequency of light.
Radio waves -ALWAYS- travel at the speed of light because they ARE light.
That being said, we have very fundamental laws of physics that are broken if you attempt to go faster than the speed of light through space - If we are ever able to move faster than the speed of light it will actually be us moving space itself.
So no, I don't believe it. I could be convinced with a suitable report, but I have never seen one.

BTW, the links that 'OBSERVER' reported are not about any information traveling faster than the speed of of light, it is about the "group velocity" traveling faster than the speed of light. It contains no information and the individual particles are not breaking the speed of light.
