Time enables one to calculate the speed I must drive to
the lesbian sperm bank with the jizz I just yanked into the tupperware container nestled lovingly between my thighs. ![]() On mister State trooper..please don't stop me...how'n my gonna xplain this ?? State Trooper Lyrics Artist(Band):Bruce Springsteen New Jersey Turnpike ridin' on a wet night 'neath the refinery's glow, out where the great black rivers flow License, registration, I ain't got none but I got a clear conscience 'Bout the things that I done (sperm donations) Mister state trooper, please don't stop me Please don't stop me, please don't stop me Maybe you got a kid (mine were conceived by lesbians using a turkey baster), maybe you got a pretty wife the only thing that I got's been both'rin' me my whole life Mister state trooper, please don't stop me Please don't stop me, please don't stop me In the wee wee hours your mind gets hazy, radio relay towers lead me to my baby Radio's jammed up with talk show stations It's just talk, talk, talk, talk, till you lose your patience Mister state trooper, please don't stop me Hey, somebody out there, listen to my last prayer |

Looking at Paulus' femtosecond interference experiments:http://faculty.physics.tamu.edu/ggp/ I say that it looks like resonance. The laser is an harmonic oscillator and then it is phase-dependent, so it looks like much as a resonance phenomenon.

Rex Clearly, time requires a change momentum in order to have any physical meaning. Time is meaningless without "events" and events amount to a change in position of at least some particle somewhere. This change in position of course requires a transfer of momentum. At absolute zero (another unattainable abstraction), time would not exist (or at least, it would have no physical meaning) because nothing would be moving. Changes in momentum are imparted by the fundamental forces, which are in turn generated by virtual messenger particles in quantum "fields". (Or so my physics professors said fifteen years ago). So it seems to me that the nature of time is rooted in the nature of these forces and the field particles that create them. |

Of course you would have to consider the atom to be a probabilistic enrichment of length with some type of structure associated with it. The nice thing about this view is that it explains the relationship between mass and gravity quite nicely. Not only says what gravity and matter is made of, but why one is associated with the other. The statement that time (or length) is probabilistic - could robably be reworded as: by hypothesis: The now (or here) cannot be known with infinite precision. If you pick a point in space, there is a nonzero probability that it will be located at a slightly different place. Same thing with time, (the now). There is only one way to make any of this work, Existential Indeterminacy. I'd like to be able to falsify that the interference in Pauls' experiment might have come from such a thing. |

See this for instance: http://www.sciam.com/article.cfm?art...c=most_popular Roberts Roberts your brother time traveller Paul Davies is a great scientist because he can extract money from various time machines built on Einstein's theories of relativity: http://www.sciam.com/article.cfm?art...c=most_popular "Our best understanding of time comes from Einstein's theories of relativity....In effect, Sally has leaped nine years into Earth's future.....Speed is one way to jump ahead in time. Gravity is another. In his general theory of relativity, Einstein predicted that gravity slows time." But your brother time traveller Paul Davies is more than just a great scientist Roberts Roberts. Paul Davies is a genius because Paul Davies is ready to start extracting money even from the fact that the speed of light is variable, a fact that topples Einstein's relativities. This will happen only if the variable speed of light is introduced by Paul Davies's friend, Joao Magueijo: http://www.prospect-magazine.co.uk/a...ls.php?id=5538 "Was Einstein wrong? The idea of a variable speed of light, championed by an angry young scientist, could one day topple Einstein's theory of relativity." Paul Davies Joao Magueijo says the speed of light varies with time but does not say it varies with the gravitational potential or the relative speed of the light source and the observer. In Einstein zombie world this means money could be extracted from toppling Einstein's relativity, on one hand, but also from not toppling it and continuing to use it for building various time machines, on the other. For that reason Paul Davies and Joao Magueijo are friends. Big friends. Like Don Corleone and Don Tataglia. Paul Davies and Joao Magueijo know nothing about people claiming the equation c'=c+v is correct, and do not want to know anything about them. Those people die in oblivion but sometimes manage to write a book while dying: http://www.ekkehard-friebe.de/wallace.htm Pentcho Valev |
