I have no difficulty with the concept that time and distance being related
in an inversely proportionate manners and that as a consequence c is always measured at c or constant in any local state of time distance proportions that are energy equivalent. But to from this to concluded that the energy in these states can not have any relative velocity or that c is a limiting velocity leaves me gob smacked. Perhaps somebody can explain how these conclusions can be reached in a non assertive manner ? as I can find no hard evidence for these beliefs just a load of misconceptions. D & R *** E-field = Electric field, M-field =Magnetic field, two unbound field effects http://home.freeuk.com/paulps/ Maybe updates. The spuds, beans and onions are coming up nicely. Ooh ah.{:-) |

I for sure can't explain it. I am as confused as you. More-so it seems. A drag racer goes east for a while then goes west for a while. His displacement is zero but time has elapesd and fuel was burned. Doing it faster just burns more fuel. The displacement is still zero. Truely baffeling. [eyes crossed] Sue... |

I don't understand what you ask about energy. About limiting velocity, a straightforward explanation is the following: According to SRT, the relativistic mass increases with speed by the factor gamma. As a matter of fact, that was the first prediction of SRT that was verified to be correct (eventhough Lorentz and Einstein used another, rather awkward definition of mass). Thus as a particle is accelerated towards c, its momentum increases towards infinity. Obviously, it's impossible to accelerate anything that has infinite momentum. Cheers, Harald |

Richard Feynman avoided this problem with renormalization whereby infinity is subtracted from infinity and the correct experimental result was substituted into the equation. Sensible mathematics involves neglecting a quantity when it turns out to be small - not neglecting it just because it is infinitely great and you do not want it! --Paul Dirac ---- Sue... |

Micky has gloves on both his hands so I see nothing pointy about time. I know you are not speaking of a vector because we can add 180 degrees to those and make them reverse. Even turning Mickey's gloves inside out will not make his hands go backward. How would I describe one of these "points in time" if I wanted to sell it on e-Bay ? I have sold a few broken meter sticks so it would not be too much different ...Eh ? ;-) Sue... |
