Revolution in Fundamental Physics: Variable Speed of Light
"Lee [Smolin] and I discussed these paradoxes at great length for many months, starting in January 2001. We would meet in cafés in South Kensington or Holland Park to mull over the problem. THE ROOT OF ALL THE EVIL WAS CLEARLY SPECIAL RELATIVITY. All these paradoxes resulted from well known effects such as length contraction, time dilation, or E=mc^2, all basic predictions of special relativity. And all denied the possibility of establishing a well-defined border, common to all observers, capable of containing new quantum gravitational effects." Joao Magueijo, Faster Than the Speed of Light, p. 250 http://www.amazon.com/Faster-Than-Sp.../dp/0738205257
What scientific idea is ready for retirement? Steve Giddings: "Spacetime. Physics has always been regarded as playing out on an underlying stage of space and time. Special relativity joined these into spacetime... [...] The apparent need to retire classical spacetime as a fundamental concept is profound..." https://www.edge.org/response-detail/25477 Joao Magueijo: "So we have broken fundamentally this Lorentz invariance which equates space and time..." https://youtu.be/kbHBBtsrU1g?t=1431 "You want to go back to a notion of space-time that preceded the 20th century, and it wants to ignore the essential lessons about space-time that the 20th century has taught us." Joao Magueijo: "Yes, that's right. So it's nouveau-Newtonian." At 53:29 he http://pirsa.org/displayFlash.php?id=16060116 Special relativity is a deductive theory so if it is "the root of all the evil", if space-time is to be broken, retired etc, then an axiom (postulate) must be false. It is highly unlikely that the falsehood is the principle of relativity - the only reasonable suggestion is: Einstein's 1905 constant-speed-of-light postulate is false. The problem is that the truth - variable speed of light, as per Newton - will completely destroy fundamental physics. Things will have to restart from scratch: "The whole of physics is predicated on the constancy of the speed of light," Joao Magueijo, a cosmologist at Imperial College London and pioneer of the theory of variable light speed, told Motherboard. "So we [Niayesh Afshordi and Joao Magueijo] had to find ways to change the speed of light without wrecking the whole thing too much." https://motherboard.vice.com/en_us/a...t-speed-slowed Awful dilemma, isn't it? Afshordi and Magueijo are honest enough but still they beat about the bush a bit, so in this tweet https://twitter.com/pentcho_valev/st...89439147859970 I tried to define the dilemma as clearly as possible. The tweet received a like from... Niayesh Afshordi! Do we need the truth, even though it will completely destroy fundamental physics? Yes we do: https://pbs.twimg.com/media/Dsi1me8WsAANyer.jpg Pentcho Valev |
