Default EINSTEIN'S NONEXISTENT SPACE-TIME

http://shass.mit.edu/news/news-2015-...ory-relativity
"Wherever you may be on the space-time continuum, it's time to celebrate!"

It would be difficult to be anywhere on the space-time continuum - it does not exist:

https://www.youtube.com/watch?v=U47kyV4TMnE
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."

https://edge.org/response-detail/25477
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..."

http://www.newscientist.com/article/...erse-tick.html
"...says John Norton, a philosopher based at the University of Pittsburgh, Pennsylvania. Norton is hesitant to express it, but his instinct - and the consensus in physics - seems to be that space and time exist on their own. The trouble with this idea, though, is that it doesn't sit well with relativity, which describes space-time as a malleable fabric whose geometry can be changed by the gravity of stars, planets and matter."

http://www.guardian.co.uk/books/2013...reality-review
"And by making the clock's tick relative - what happens simultaneously for one observer might seem sequential to another - Einstein's theory of special relativity not only destroyed any notion of absolute time but made time equivalent to a dimension in space: the future is already out there waiting for us; we just can't see it until we get there. This view is a logical and metaphysical dead end, says Smolin."

http://www.amazon.com/Time-Reborn-Cr.../dp/0547511728
"Was Einstein wrong? At least in his understanding of time, Smolin argues, the great theorist of relativity was dead wrong. What is worse, by firmly enshrining his error in scientific orthodoxy, Einstein trapped his successors in insoluble dilemmas..."

Why is Einstein's space-time nonexistent? Because it is an absurd consequence of Einstein's assumption (postulate) that the speed of light is constant.. In fact the speed of light is variable. When an observer starts moving towards a light source with (small) speed v, the frequency he measures shifts from f=c/λ to f'=(c+v)/λ, where c is the speed of the waves relative to a stationary observer and λ is the wavelength.

Question: Why does the frequency shift from f=c/λ to f'=(c+v)/λ?

Answer 1 (fatal for Einstein's relativity): Because the speed of the waves relative to the observer shifts from c to c'=c+v (that is, relative to the observer, the speed of the light is now greater than c).

Answer 2 (possibly saving Einstein's relativity): Because...

There is no reasonable statement that could become Answer 2:

"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://farside.ph.utexas.edu/teachin...ml/node41.html
"Thus, the moving observer sees a wave possessing the same wavelength (...) but a different frequency (...) to that seen by the stationary observer."

http://physics.bu.edu/~redner/211-sp...9_doppler.html
"We will focus on sound waves in describing the Doppler effect, but it works for other waves too. (...) 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."

Clever Einsteinians have always known that the speed of light varies with the speed of the observer. Here is an implicit confession:

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 "the distances between subsequent pulses are not affected", and since "four pulses are received in the time it takes the source to emit three pulses", the speed of the light as measured by the receiver (observer) is:

c' = 4d/t = (4/3)(3d/t) = (4/3)c

where d is the distance between subsequent pulses, t is "the time it takes the source to emit three pulses", and c=3d/t is the initial speed of the light (as measured by the source).

Clearly the speed of light (relative to the observer) varies with the speed of the observer, as predicted by Newton's emission theory of light and in violation of Einstein's relativity.

Default EINSTEIN'S NONEXISTENT SPACE-TIME

http://community.bowdoin.edu/news/20...rs-of-gravity/
"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."

There was no such "observation". Rather, all reliable evidence shows that the speed of light is variable, as predicted by Newton's emission theory of light:

http://www.amazon.com/Introduction-S.../dp/048668895X
Introduction to Special Relativity, James H. Smith, p. 42: "We must emphasize that at the time Einstein proposed it [his second postulate], there was no direct experimental evidence whatever for the speed of light being independent of the speed of its source."

http://www.martinezwritings.com/m/Relativity.html
"Does the speed of light depend on the speed of its source? Before formulating his theory of special relativity, Albert Einstein spent a few years trying to formulate a theory in which the speed of light depends on its source, just like all material projectiles. Likewise, Walter Ritz outlined such a theory, where none of the peculiar effects of Einstein's relativity would hold. By 1913 most physicists abandoned such efforts, accepting the postulate of the constancy of the speed of light. Yet five decades later all the evidence that had been said to prove that the speed of light is independent of its source had been found to be defective."

http://www.philoscience.unibe.ch/doc...S07/Norton.pdf
"These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day."

http://philsci-archive.pitt.edu/1743/2/Norton.pdf
"In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE."

http://books.google.com/books?id=JokgnS1JtmMC
"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."

http://www.einstein-online.info/spot...t_white_dwarfs
Albert Einstein Institute: "One of the three classical tests for general relativity is the gravitational redshift of light or other forms of electromagnetic radiation. However, in contrast to the other two tests - the gravitational deflection of light and the relativistic perihelion shift -, you do not need general relativity to derive the correct prediction for the gravitational redshift. A combination of Newtonian gravity, a particle theory of light, and the weak equivalence principle (gravitating mass equals inertial mass) suffices. (...) The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..."

http://press.princeton.edu/titles/8169.html
Richard Feynman, "QED: The strange theory of light and matter", p. 15: "I want to emphasize that light comes in this form - particles. It is very important to know that light behaves like particles, especially for those of you who have gone to school, where you probably learned something about light behaving like waves. I'm telling you the way it does behave - like particles. You might say that it's just the photomultiplier that detects light as particles, but no, every instrument that has been designed to be sensitive enough to detect weak light has always ended up discovering the same thing: light is made of particles."

Default EINSTEIN'S NONEXISTENT SPACE-TIME

http://philsci-archive.pitt.edu/1661/1/Minkowski.pdf
MINKOWSKI SPACE-TIME: A GLORIOUS NON-ENTITY, Harvey Brown and Oliver Pooley: "What has been shown is that rods and clocks must behave in quite particular ways in order for the two postulates to be true together. But this hardly amounts to an explanation of such behaviour. Rather things go the other way around. It is because rods and clocks behave as they do, in a way that is consistent with the relativity principle, that light is measured to have the same speed in each inertial frame."

But this is a cosmic conspiracy of the highest order, isn't it? Neil deGrasse Tyson and Brian Greene wholeheartedly agree:

http://astro.cornell.edu/academics/c...speedlimit.htm
Neil deGrasse Tyson: "If everyone, everywhere and at all times, is to measure the same speed for the beam from your imaginary spacecraft, a number of things have to happen. First of all, as the speed of your spacecraft increases, the length of everything - you, your measuring devices, your spacecraft - shortens in the direction of motion, as seen by everyone else. Furthermore, your own time slows down exactly enough so that when you haul out your newly shortened yardstick, you are guaranteed to be duped into measuring the same old constant value for the speed of light. What we have here is a COSMIC CONSPIRACY OF THE HIGHEST ORDER."

http://www.pbs.org/wgbh/nova/physics...-nutshell.html
Brian Greene: "If space and time did not behave this way, the speed of light would not be constant and would depend on the observer's state of motion.. But it is constant; space and time do behave this way. Space and time adjust themselves in an exactly compensating manner so that observations of light's speed yield the same result, regardless of the observer's velocity."

https://www.youtube.com/watch?v=BuxFXHircaI
Michio Kaku, Brian Cox, Neil deGrasse Tyson, Brian Greene, Lisa Randall: "Light travels at the same speed no matter how you look at it. No matter how I move relative to you light travels at the same speed. No matter who is doing the measurement and no matter what direction you are moving the speed of light is the same. The speed of light is the same no matter what direction or how fast... As you travel faster time slows down. Everything slows down. Everything slows down. Time slows down when you move. Time passes at a different rate. Clocks run slow. It's a monumental shift in how we see the world. It's a beautiful piece of science. It's a beautifully elegant theory.. It's a beautiful piece of science. It's a beautiful piece..."
