Default THE SECRET TO THE TWIN PARADOX

http://www.amazon.com/Relativity-Its.../dp/0486406768
Relativity and Its Roots, Banesh Hoffmann, p. 105: "In one case your clock is checked against two of mine, while in the other case my clock is checked against two of yours, and this permits us each to find without contradiction that the other's clocks go more slowly than his own."

Einsteiniana's scenarios allow the travelling twin's clock to be checked against two clocks in the sedentary twin's system - e.g. clocks situated at the initial and final points of the travelling twin's trip. However Einsteiniana's scenarios NEVER allow the sedentary twin's clock to be checked against two clocks in the travelling twin's system - e.g. clocks situated at the front and back ends of a (very long) rocket. Such biased scenarios convert the RECIPROCAL time dilation predicted by special relativity into an asymmetric time dilation - the travelling twin always returns younger so that Einsteinians can sing "Yes we all believe in relativity, relativity, relativity" and go into convulsions.

It is easy to imagine a scenario in which, while the travelling twin performs the forward part of trip, the sedentary twin's clock effectively moves from the front end to the back end of a (very long) rocket. Then, as the travelling twin returns, the sedentary twin's clock effectively moves from the back end to the front end of the rocket.

In this scenario time dilation is RECIPROCAL again and special relativity gloriously predicts that, when the brothers finally meet, either of them is younger than the other.

Default THE SECRET TO THE TWIN PARADOX

Doublethink practiced in Einsteiniana is somewhat different from (classical) doublethink as defined by George Orwell. In classical doublethink truth and lie coexist:

http://www.liferesearchuniversal.com/1984-17
"Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them. The Party intellectual knows in which direction his memories must be altered; he therefore knows that he is playing tricks with reality; but by the exercise of doublethink he also satisfies himself that reality is not violated. The process has to be conscious, or it would not be carried out with sufficient precision, but it also has to be unconscious, or it would bring with it a feeling of falsity and hence of guilt. Doublethink lies at the very heart of Ingsoc, since the essential act of the Party is to use conscious deception while retaining the firmness of purpose that goes with complete honesty. To tell deliberate lies while genuinely believing in them, to forget any fact that has become inconvenient, and then, when it becomes necessary again, to draw it back from oblivion for just so long as it is needed, to deny the existence of objective reality and all the while to take account of the reality which one denies - all this is indispensably necessary."

Doublethink as practiced in Einsteiniana means the power of holding two contradictory interpretations of the same lie in one's mind simultaneously, and accepting both of them. Truth is nowhere to find. So it is universally taught that the travelling twin does return younger, Divine Einstein, yes we all believe in relativity, relativity, relativity, but half of the Einsteinians teach that the youthfulness of the travelling twin has nothing to do with the acceleration she has suffered while the other half teach that the travelling twin's youthfulness is entirely caused by the acceleration she has suffered:

http://www.damtp.cam.ac.uk/research/...tivity2010.pdf
Gary W. Gibbons FRS: "In other words, by simply staying at home Jack has aged relative to Jill. There is no paradox because the lives of the twins are not strictly symmetrical. This might lead one to suspect that the accelerations suffered by Jill might be responsible for the effect. However this is simply not plausible because using identical accelerating phases of her trip, she could have travelled twice as far. This would give twice the amount of time gained."

http://www.informaworld.com/smpp/con...ent=a909857880
Peter Hayes, in "The Ideology of Relativity: The Case of the Clock Paradox" : Social Epistemology, Volume 23, Issue 1 January 2009, pages 57-78, quotes Einstein writing in 1911: "The [travelling] clock runs slower if it is in uniform motion, but if it undergoes a change of direction as a result of a jolt, then the theory of relativity does not tell us what happens. The sudden change of direction might produce a sudden change in the position of the hands of the clock. However, the longer the clock is moving rectilinearly and uniformly with a given speed in a forward motion, i.e., the larger the dimensions of the polygon, the smaller must be the effect of such a hypothetical sudden change."

http://www.pitt.edu/~jdnorton/teachi...yon/index.html
John Norton: "Then, at the end of the outward leg, the traveler abruptly changes motion, accelerating sharply to adopt a new inertial motion directed back to earth. What comes now is the key part of the analysis. The effect of the change of motion is to alter completely the traveler's judgment of simultaneity. The traveler's hypersurfaces of simultaneity now flip up dramatically. Moments after the turn-around, when the travelers clock reads just after 2 days, the traveler will judge the stay-at-home twin's clock to read just after 7 days. That is, the traveler will judge the stay-at-home twin's clock to have jumped suddenly from reading 1 day to reading 7 days. This huge jump puts the stay-at-home twin's clock so far ahead of the traveler's that it is now possible for the stay-at-home twin's clock to be ahead of the travelers when they reunite."

http://en.wikisource.org/wiki/Dialog...f_rela tivity
Dialog about Objections against the Theory of Relativity (1918), by Albert Einstein: "...according to the special theory of relativity the coordinate systems K and K' are by no means equivalent systems. Indeed this theory asserts only the equivalence of all Galilean (unaccelerated) coordinate systems, that is, coordinate systems relative to which sufficiently isolated, material points move in straight lines and uniformly. K is such a coordinate system, but not the system K', that is accelerated from time to time. Therefore, from the result that after the motion to and fro the clock U2 is running behind U1, no contradiction can be constructed against the principles of the theory. (...) During the partial processes 2 and 4 the clock U1, going at a velocity v, runs indeed at a slower pace than the resting clock U2. However, this is more than compensated by a faster pace of U1 during partial process 3. According to the general theory of relativity, a clock will go faster the higher the gravitational potential of the location where it is located, and during partial process 3 U2 happens to be located at a higher gravitational potential than U1. The calculation shows that this speeding ahead constitutes exactly twice as much as the lagging behind during the partial processes 2 and 4. This consideration completely clears up the paradox that you brought up."

Default THE SECRET TO THE TWIN PARADOX

We have multiple clocks regularly scattered and fixed on the periphery of a rotating disc and a single non-rotating clock at rest situated outside the disc but very close to the periphery. This clock constantly compares its reading with the readings of rotating clocks passing by. Initially the disc is immobile and all clocks are synchronous but then the disc starts rotating and eventually a constant linear speed of the periphery is reached.

Does the difference:

(clock-at-rest reading) - (rotating-clock reading)

increase, decrease or remain constant (zero) as the number of comparisons increases? Einsteinians answer immediately:

"The difference increases because Divine Albert said so, yes we all believe in relativity, relativity, relativity!"

Yet by increasing the perimeter of the disc while keeping the linear speed of the periphery constant, one converts clocks fixed on the periphery into VIRTUALLY INERTIAL clocks (the "gravitational field" they experience is reduced to zero). So the clock at rest is repeatedly checked against two clocks fixed on the periphery - according to special relativity, the clock at rest is found to run more slowly than the clocks on the periphery:

http://www.amazon.com/Relativity-Its.../dp/0486406768
Relativity and Its Roots, Banesh Hoffmann, p. 105: "In one case your clock is checked against two of mine, while in the other case my clock is checked against two of yours, and this permits us each to find without contradiction that the other's clocks go more slowly than his own."

This means that the difference:

(clock-at-rest reading) - (rotating-clock reading)

decreases. Since special relativity also predicts that the difference increases (Divine Albert is right about that), we just have REDUCTIO AD ABSURDUM.. The consequent is absurd, therefore the antecedent (Einstein's 1905 light postulate) is false.

Default THE SECRET TO THE TWIN PARADOX

Divine Albert fools relativity believers:

http://www.bartleby.com/173/23.html
Albert Einstein: "An observer who is sitting eccentrically on the disc K' is sensible of a force which acts outwards in a radial direction... (...) The observer performs experiments on his circular disc with clocks and measuring-rods. In doing so, it is his intention to arrive at exact definitions for the signification of time- and space-data with reference to the circular disc K', these definitions being based on his observations. What will be his experience in this enterprise? To start with, he places one of two identically constructed clocks at the centre of the circular disc, and the other on the edge of the disc, so that they are at rest relative to it. We now ask ourselves whether both clocks go at the same rate from the standpoint of the non-rotating Galileian reference-body K. As judged from this body, the clock at the centre of the disc has no velocity, whereas the clock at the edge of the disc is in motion relative to K in consequence of the rotation. According to a result obtained in Section XII, it follows that the latter clock goes at a rate permanently slower than that of the clock at the centre of the circular disc, i.e. as observed from K."

In fact, Section XII in Divine Albert's book does not contain any results explaining why the clock at the centre of the rotating disc should run FASTER than the clock at the edge of the disc. Rather, the results in Section XII are all based on the Lorentz transformation which predicts RECIPROCAL time dilation for inertial observers - either observer sees the other observer's clock running SLOW. The Lorentz transformation does not predict anything about a system of two clocks one of which (the one at the edge of the disc) is not inertial.

Needless to say, relativity believers would never go to Section XII and see if the results there justify Divine Albert's claim that the clock at the center runs faster. They just sing "Yes we all believe in relativity, relativity, relativity" and, when the ecstasy reaches its culmination, go into convulsions. If Divine Albert had said that it is the clock at the edge that runs faster, relativity believers would be just as ecstatic.

Default THE SECRET TO THE TWIN PARADOX

Paradox in the twin paradox:

Special relativity predicts that, when two inertial observers pass one another with relative speed v, either of them sees the other's clock running SLOW by a factor of 1/gamma = sqrt(1-(v/c)^2). This prediction is false of course but it VALIDLY follows from the postulates - its falsehood is due to the falsehood of Einstein's 1905 light postulate.

In his 1920 book Divine Albert claims that, if one of the observers experiences a centrifugal force (being fixed on the periphery of a rotating disc), then he sees the other observer's clock running FAST by a factor of gamma = 1/sqrt(1-(v/c)^2), no matter the magnitude of the force (it could be virtually zero):

http://www.bartleby.com/173/23.html
Albert Einstein. Relativity: The Special and General Theory. 1920. XXIII. Behaviour of Clocks and Measuring Rods on a Rotating Body of Reference.

Divine Albert's 1920 claim is just a blatant lie - it does not follow from the postulates of special relativity. However, intensely repeated for a century, the blatant lie is now an absolute truth. By fighting it, antirelativists find themselves in the unfortunate position of defending the genuine special relativity against additional absurdities introduced by Divine Albert.

Einstein believed that the universe was not expanding, if you believe that it is, then you must admit that Einstein was wrong.
