Default DID NASA ACCELERATE LIGHT?

http://www.preposterousuniverse.com/...fic-reasoning/
Sean Caroll: "The folks in this particular "Eagleworks" group at Johnson Spaceflight Center are a group of enthusiasts who feel that gumption and a bit of elbow grease might possibly enable them to build spaceships that do things beyond what the laws of physics might naively let you do. And good for them! Enthusiasm is a virtue. Less virtuous is taking people's enthusiasm at face value, rather than evaluating claims soberly. The Eagleworks group has succeeded in producing, essentially, nothing at all. Their primary mode of communication seems to be on Facebook. NASA officials, when asked by journalists for comment on the claims they leave on websites, remain silent - they don't want to have anything to do with the whole mess. So what we have is a situation where there's a claim being made that is as extraordinary as it gets - conservation of momentum is being violated. And the evidenced adduced for that claim is, how shall we put it, non-extraordinary. Utterly unconvincing. Not worth a minute's thought. Let's get on with our lives."

There could be another reason why NASA officials are silent - the Eagleworks group seems to have made laser beams travel faster than the speed of light, in violation of Einstein's relativity:

http://www.ibtimes.co.uk/emdrive-war...mdrive-1501268
"On 29 April, Nasa scientists wrote an article on Nasa Spaceflight that they had tested British scientist Roger Shawyer's controversial electromagnetic space propulsion technology called EmDrive and were unable to disprove their results, indicating that the technology worked. However forum users looking at the experiment results also found that when lasers were fired into the EmDrive's resonance chamber, some of the laser beams had travelled faster than the speed of light..."

"Thrust measurements of the EmDrive defy classical physics' expectations", said the researchers, who have been testing the highly controversial electromagnetic space propulsion technology. They posted on the Nasa Spaceflight forum that when lasers were fired into the EmDrive's resonance chamber, some of the laser beams had travelled faster than the speed of light..."

So did laser beams travel faster than the speed of light? Are NASA officials going to reply? A few months ago Scottish scientists managed to slow down light inside vacuum but the result, published in Science, is now long forgotten:

http://rt.com/news/225879-light-speed-slow-photons/
"Physicists manage to slow down light inside vacuum (...) ...even now the light is no longer in the mask, it's just the propagating in free space - the speed is still slow. (...) "This finding shows unambiguously that the propagation of light can be slowed below the commonly accepted figure of 299,792,458 metres per second, even when travelling in air or vacuum," co-author Romero explains in the University of Glasgow press release."

http://www.upi.com/Science_News/2015.../1191422035480
"The speed of light is a limit, not a constant - that's what researchers in Glasgow, Scotland, say. A group of them just proved that light can be slowed down, permanently."

The Scottish scientists did prove that the speed of light is not constant, most probably NASA scientists confirmed that, but the scientific world is unable to accept the catastrophe:

http://www.amazon.com/Faster-Than-Sp.../dp/0738205257
Faster Than the Speed of Light, Joao Magueijo: "If there's one thing every schoolboy knows about Einstein and his theory of relativity, it is that the speed of light in vacuum is constant. No matter what the circumstances, light in vacuum travels at the same speed - a constant that physicists denote by the letter c: 300,000 km per second, or as Americans refer to it, 186,000 miles per second. The speed of light is the very keystone of physics, the seemingly sure foundation upon which every modern cosmological theory is built, the yardstick by which everything in the universe is measured. (...) The only aspect of the universe that didn't change was the speed of light.. And ever since, the constancy of the speed of light has been woven into the very fabric of physics, into the way physics equations are written, even into the notation used. Nowadays, to "vary" the speed of light is not even a swear word: It is simply not present in the vocabulary of physics."

http://www.kritik-relativitaetstheor...-of-physics-2/
Bryan Wallace: "Einstein's special relativity theory with his second postulate that the speed of light in space is constant is the linchpin that holds the whole range of modern physics theories together. Shatter this postulate, and modern physics becomes an elaborate farce! (...) The speed of light is c+v."

http://www.perimeterinstitute.ca/pdf...09145525ca.pdf
Albert Einstein (1954): "I consider it entirely possible that physics cannot be based upon the field concept, that is on continuous structures. Then nothing will remain of my whole castle in the air, including the theory of gravitation, but also nothing of the rest of contemporary physics."

How did Einstein base his theory on the field concept? By adopting the constancy of the speed of light as defined by the ether field theory:

http://arxiv.org/ftp/physics/papers/0101/0101109.pdf
"The two first articles (January and March) establish clearly a discontinuous structure of matter and light. The standard look of Einstein's SR is, on the contrary, essentially based on the continuous conception of the field.."

http://www.pbs.org/wgbh/nova/einstein/genius/
"And then, in June, Einstein completes special relativity, which adds a twist to the story: Einstein's March paper treated light as particles, but special relativity sees light as a continuous field of waves."

http://books.google.com/books?id=JokgnS1JtmMC
Relativity and Its Roots, Banesh Hoffmann, p.92: "There are various remarks to be made about this second principle. For instance, if it is so obvious, how could it turn out to be part of a revolution - especially when the first principle is also a natural one? Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether. If it was so obvious, though, why did he need to state it as a principle? Because, having taken from the idea of light waves in the ether the one aspect that he needed, he declared early in his paper, to quote his own words, that "the introduction of a 'luminiferous ether' will prove to be superfluous."
