Tom, The speed of light in air is not vastly different from the speed of light in a vacuum. If photons were apparently travelling at 1.7 times the speed of light in air, they clearly must have been exceeding the speed of light in a vacuum. This result was observed using visible light. Current theory is usually quoted as nothing can travel faster than the speed of light in a vaccum. It is probably more correct to state that objects with mass cannot exceed the speed of light in a vacuum. Photons, having no mass, are not necessarily subject to this rule and seem to be observed travelling at superluminal velocity under certain very specific conditions. If the photons are tunnelling and travelling faster than light in a vacuum, it does not necessarily mean that any laws have been broken. One way of imagining a way in which this could happen is if a block of material is energised to a high energy state. Photons are continually fired into the material and are absorbed one by one with atoms within the structure absorbing each new photon. At some point, the material becomes completely saturated and cannot absorb any more photons. When the next photon hits and is absorbed, a shockwave propogates through the material and a photon is emitted from the opposite side travelling at the same speed and in the same direction as the original absorbed photon. Stability is restored and energy is conserved. But, it is the shockwave that has propogated faster than the speed of light and it is not the original photon that entered the material that is emitted. The emitted photon will contain exactly the same properties as the absorbed photon and the two would be indistinguishable. So the photon appears to have been transmitted through the material at faster than light speed, but no laws have been broken. A Newtons cradle can help with visualising how this can happen. Mike G0ULI Mike, You had me fooled. It appeared that you might actually know something. But that response bent the needle on my bull**** meter. 73, Gene W4SZ |

Clearly the experimental results demonstrate something odd is happening in the laboratory and photons are apparently exceeding light speed, which they shouldn't be able to do in light of current knowledge. I think it must have been a mention of Newton together with quantum phenomena that upsets people :-) Regards Mike G0ULI |

Jimmie Jimmie, No particular argument about electrons in a wire. However, the stuff proposed by Mike bears little resemblance to the wire. How about: Atoms absorbing photons one by one, i.e. one per atom in a solid? Doesn't match anything I have ever learned. Material becomes saturated with photons? What is this, a bag of marbles? Shockwave propagates faster than speed of light? (Yes, I am familiar with Cerenkov radiation. Not interesting in this context.) Emitted photons contains exactly the same properties as the absorbed photon? How do they get absorbed yet remember everything? How do they know when and where they should pop out the other side? Every part of that proposed explanation was nonsense. 73, Gene W4SZ |

Unfortunately this isn't the sort of research that can be conducted by an amateur in a shed in the back yard. Unless commercial applications for experimental findings are found, funds are rapidly switched to other areas of research looking for a new discovery that might make a profit. It's just the way that capitalism works. Mike G0ULI |

It's just the way that capitalism works. Mike G0ULI This is EXACTLY why it Art is having such a difficult time with his Gaussian antenna project. I think it highly unlikely that aluminium foil on tapered fish-poles will offer the repeatability that Gaussian equilibrium demands, since the skin depth is so large in ALL units. Perhaps if he made better models available, those of us who have a true desire to see his work progress would be able to contribute something to advancement of antenna history. Mike W5CHR |
