Einsteinians Repudiate Einstein's Spacetime

Nobel Laureate David Gross observed, "Everyone in string theory is convinced...that spacetime is doomed. But we don't know what it's replaced by."

Nima Arkani-Hamed (06:11): "Almost all of us believe that space-time doesn't really exist, space-time is doomed and has to be replaced by some more primitive building blocks."

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..."

"Rethinking Einstein: The end of space-time [...] The stumbling block lies with their conflicting views of space and time. As seen by quantum theory, space and time are a static backdrop against which particles move. In Einstein's theories, by contrast, not only are space and time inextricably linked, but the resulting space-time is moulded by the bodies within it. [...] Something has to give in this tussle between general relativity and quantum mechanics, and the smart money says that it's relativity that will be the loser."

So David Gross doesn't know what spacetime is replaced by. There is not much choice. Spacetime is an "immediate consequence" of Einstein's constant-speed-of-light postulate:

"Baumgarte began by discussing special relativity, which Einstein developed, 10 years earlier, in 1905, while he was employed as a patent officer in Bern, Switzerland. Special relativity is based on the observation that the speed of light is always the same, independently of who measures it, or how fast the source of the light is moving with respect to the observer. Einstein demonstrated that as an immediate consequence, space and time can no longer be independent, but should rather be considered a new joint entity called "spacetime."

Since the "immediate consequence", spacetime, does not exist, is doomed, and has to be "retired", the underlying premise, Einstein's constant-speed-of-light postulate, is false, isn't it, David Gross? Logic forbids the combination "true premise, wrong consequence".

Einstein parted from Newton's theory when he adopted the ether theory's (false) tenet stating that the speed of light is constant (independent of the speed of the light source):

"Relativity and Its Roots" by 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."

Clearly, since Einstein's constant-speed-of-light postulate is false, the only replacement for Einstein's idiotic spacetime are Newton's space and time.

The constancy of the speed of light is so obviously absurd (variability is so obviously correct) that sometimes Einsteinians inadvertently refute Einstein's relativity by demonstrating that the speed of light varies with the speed of the observer (receiver):

http://www.einstein-online.info/spotlights/doppler
Albert Einstein Institute: "The frequency of a wave-like signal - such as sound or light - depends on the movement of the sender and of the receiver. This is known as the Doppler effect. [...] Here is an animation of the receiver moving towards the source:

http://www.einstein-online.info/imag...ler_static.gif (stationary receiver)

http://www.einstein-online.info/imag...ector_blue.gif (moving receiver)

By observing the two indicator lights, you can see for yourself that, once more, there is a blue-shift - the pulse frequency measured at the receiver is somewhat higher than the frequency with which the pulses are sent out. This time, the distances between subsequent pulses are not affected, but still there is a frequency shift: As the receiver moves towards each pulse, the time until pulse and receiver meet up is shortened. In this particular animation, which has the receiver moving towards the source at one third the speed of the pulses themselves, four pulses are received in the time it takes the source to emit three pulses." [end of quotation]

Since "four pulses are received in the time it takes the source to emit three pulses", the speed of the pulses relative to the receiver is greater than their speed relative to the source, in violation of Einstein's relativity..

Actually any correct interpretation of the Doppler effect proves, explicitly or implicitly, that the speed of light relative to the observer VARIES with the speed of the observer:

"Doppler effect - when an observer moves towards a stationary source. ...the velocity of the wave relative to the observer is faster than that when it is still."

http://www.youtube.com/watch?v=SC0Q6-xt-Xs
"Doppler effect - when an observer moves away from a stationary source. ....the velocity of the wave relative to the observer is slower than that when it is still."

http://a-levelphysicstutor.com/wav-doppler.php
"vO is the velocity of an observer moving towards the source. This velocity is independent of the motion of the source. Hence, the velocity of waves relative to the observer is c + vO. [...] The motion of an observer does not alter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time."

http://physics.bu.edu/~redner/211-sp...9_doppler.html
"Let's say you, the observer, now move toward the source with velocity vO. You encounter more waves per unit time than you did before. Relative to you, the waves travel at a higher speed: v'=v+vO. The frequency of the waves you detect is higher, and is given by: f'=v'/λ=(v+vO)/λ."

"That lecture, by the German mathematician Hermann Minkowski, established a new arena for the presentation of physics, a new vision of the nature of reality redefining the mathematics of existence. The lecture was titled Space and Time, and it introduced to the world the marriage of the two, now known as spacetime. It was a good marriage, but lately physicists passion for spacetime has begun to diminish. And some are starting to whisper about possible grounds for divorce."

The whispers will have to stop for a while until LIGO profiteers get the millions they expected to squeeze out of taxpayers (after showing them faked gravitational waves). Einstein schizophrenic world does accept absurdities but still there is an upper limit. You cannot SIMULTANEOUSLY repudiate spacetime and hail the discovery of ripples in spacetime - two or three persons in Einstein schizophrenic world may notice the contradiction. However, if today you reject spacetime, and tomorrow declare that you live for the ripples in spacetime, no one in Einstein schizophrenic world will notice any contradiction:

"We have good reason to believe general relativity is not a complete theory and, in particular, that it’s going to break down in the context of describing black holes," said UCSB physics professor Steve Giddings. "That’s very much an important problem in physics today. “The direct observation of gravitational waves from colliding black holes really constrains the possible departures from general relativity that we know are there and limits where modifications can be made," he continued. "But the discovery is still spectacular and its announcement was one of those moments in science that you live for."
