we have to differentiate particles electrons,neutrons,protons may travel at speed of light atoms no. I think you mean to say that those particles and atoms can't travel as fast as light. |

atoms cant travel faster than speed of light but those others electron neutrons protons can travel faster than light. We choose to go to the moon and to do other things, we choose to go to the moon not because its easy but because its hard. kennedy |

atoms cant travel faster than speed of light but those others electron neutrons protons can travel faster than light. Only tachyons can travel faster that light in a vacuum. Unfortunately, they have never been observed. Tullio |

http://www.springerlink.com/content/v77p538p34303130/fulltext.pdf?page=1 that will be some evidence i can give you. We choose to go to the moon and to do other things, we choose to go to the moon not because its easy but because its hard. kennedy |

atoms cant travel faster than speed of light but those others electron neutrons protons can travel faster than light. . . . matter of faCt - they travel 'approximately' 3 times the speed of Light - while @ Rest Mass - relative to ALL systems > and, they have been 'observed' - can You guess HOW? ![]() Science Status Page . . . |

No. Please give evidence. |

http://www.springerlink.com/content/v77p538p34303130/fulltext.pdf?page=1 The article you cite was published in Lettere al Nuovo Cimento, that means it was not seen by referees, as it would have happened if it had been published in Il Nuovo Cimento. Since I have published an article in Il Nuovo Cimento, Serie X, Vol. 51B, pag 195-198, 1967 (SUn,1 Representation for the Harmonic Oscillator, G.Bisiacchi and T.Chersi), Institute of Theoretical Physics, Trieste, I know the difference. |

Well i havent published any article ,so i dont think i can argue with you we shall wait for others to contribute We choose to go to the moon and to do other things, we choose to go to the moon not because its easy but because its hard. kennedy |

I have personally known prof.Erasmo Recami,one of the cited authors, and have published an article of his entitled "I tachioni" in the Scienza&Tecnica 73 Yearbook of the Mondadori Scientific Encyclopedia where I worked as a physics and astronomy editor. It is written in Italian, and I can only translate a paragraph at the end where he says "One cannot be surprised if experiences performed at the Nobel Institute, at Princeton, at Columbia University and at Brookhaven National Laboratory have not given so far a positive result". While having a degree in theoretical physics, I still think that the litmus test of any theory must be experimental evidence. So far, as far as I know, none has been found. As a final comment, it seems to me that none of the articles you cite appears to have been published in a referred journal. The bibliography cited at the end of prof.Recamis's article is more complete. but of course in 1973 Internet did not exist and articles were not available on line like today. Allow me a single quotation by Robert K.Adair, Yale University, in an article on "Missing particles" published in the book "Lepton and Hadron structure", A.Zichichi (ed,) Academic Press, 1975, pag.321 Adair says: "Tachyons. For completeness, I suppose I should list tachyons, but I have never looked for tachyons and I doubt I ever will. I am not that damned romantic. The problem of acausality with tachyons beams seems too unpleasant for my sense of esthetics." |

I thought that Tachyons were a mathematical anomaly that tends to invalidate many theories in particle physics. This is sort of like infinities popping up in these fields of endeavor or results being off by 120 orders of magnitude. |

When prof.Recami married, he sent me an invitation card. But since snail mail in Italy is really slow, I received it after his marriage. So I wrote back: dear professor, if I had a few tachyons available I would use them to send you my best wishes and they would arrive BEFORE you marry. He never replied and I don't know if he appreciated my joke (witz, in Triestino parlance). Tullio |

I thought that Tachyons were a mathematical anomaly that tends to invalidate many theories in particle physics. This is sort of like infinities popping up in these fields of endeavor or results being off by 120 orders of magnitude. It is definitely an anomaly! It is a theoretical particle that can travel faster than light! (actually quantum field theory tells us they use tachyon condensation) Thanks to Albert Einstein and his theory of relativity we know that this is a rare occurrence indeed. Of course, when we go away from the classical physics of Einstein to quantum mechanics many strange things can happen..... They also Can't slow down to subluminal speeds. In string theory tachyons not only describe the physics of tachyonic fields, but also predict whether such fields appear. Furthermore one can calculate the energy of a tachyon through: ![]() Please correct me if I screwed anything up.

Well since gravity is a sphere to earth... Speed of light may be confined to its specific gravitational field ? Therefore the speed of light is true within a specific gravitational field ? And speed of light at earth is non equal to that outside equal gravitational pull ? Or is this just a hangover ?? |

What should also be remembered is that neither Relativity nor the Quantum are, in an of themselves, complete theories. They are sometimes self-inconsistent and usually mutually exclusive. We sometimes tend to get ‘blinded by the light’ and think physics has everything pretty much figured out. Talk to a theoretical physicist some time. If you happen to get her at the at the end of a long day and looking at the bottom of her empty cooler bottle, she will admit that nothing could be further than the truth. These theories are just stepping stones and there is a long, long way to go yet. Just because something like a Tychon appears out of the math of Quantum Theory does not mean that they ever have, ever will or even could exist. It just means that the theory, like all theories, is a work in progress, Pure mathematics is, in its way, the poetry of logical ideas. Albert Einstein |

Tried Googling it but didn't come up with anything. Do you have a link? (To be honest, I never heard of these fields. Looks like a souped up Van De Graaff generator in the picture, tho. Just me and my little razor.) Pure mathematics is, in its way, the poetry of logical ideas. Albert Einstein |
