Default EINSTEIN'S SCHIZOPHRENIC THEORY

The youthfulness of the travelling twin has nothing to do with the acceleration suffered by him/her:

http://www.symmetrymagazine.org/arti...e-twin-paradox
Fermilab physicist Don Lincoln: "Some readers, probably including some readers who hold doctorates in physics, will claim that the difference between the two twins is that one of the two has experienced an acceleration. (After all, that's how he slowed down and reversed direction.) However, the relativistic equations don't include that acceleration phase..."

http://sciencechatforum.com/viewtopic.php?f=84&t=26847
Fermilab physicist Don Lincoln: "A common explanation of this paradox is that the travelling twin experienced acceleration to slow down and reverse velocity. While it is clearly true that a single person must experience this acceleration, you can show that the acceleration is not crucial. What is crucial is that the travelling twin experienced time in two reference frames, while the homebody experienced time in one. We can demonstrate this by a modification of the problem. In the modification, there is still a homebody and a person travelling to a distant star. The modification is that there is a third person even farther away than the distant star. This person travels at the same speed as the original traveler, but in the opposite direction. The third person's trajectory is timed so that both of them pass the distant star at the same time. As the two travelers pass, the Earthbound person reads the clock of the outbound traveler. He then adds the time he experiences travelling from the distant star to Earth to the duration experienced by the outbound person. The sum of these times is the transit time. Note that no acceleration occurs in this problem...just three people experiencing relative inertial motion."

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."

The youthfulness of the travelling twin is entirely due to the acceleration suffered by him/her:

http://en.wikisource.org/wiki/Dialog...f_rela tivity
Dialog about Objections against the Theory of Relativity, 1918, Albert Einstein: "During the partial processes 2 [traveller moves with constant speed away from sedentary brother] and 4 [traveller moves with constant speed towards sedentary brother] the clock U1 [the sedentary twin's clock], going at a velocity v, runs indeed at a slower pace than the resting clock U2 [the travelling twin's clock]. However, this is more than compensated by a faster pace of U1 during partial process 3 [traveller sharply turns around]. 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."

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."

Default EINSTEIN'S SCHIZOPHRENIC THEORY

A clock on the ground is at rest but a train is moving forwards and backwards so that the clock on the ground effectively commutes between a clock at the front and another at the back end of the train. The speed of the train is constant except for the turn-arounds when clocks on the train suffer sharp acceleration. Will the clock on the ground lag behind or outstrip the two clocks on the moving train?

Except for the turn-around periods, the clock on the ground runs slower than the clocks on the train (according to special relativity). Now if the turn-around acceleration is crucial, as Albert Einstein and John Norton claim, this running slower is "more than compensated by a faster pace" of the clock on the ground during the turn-around periods. If the turn-around acceleration is not crucial, as Don Lincoln and Gary Gibbons claim, the clock on the ground lags behind the clocks on the train in this scenario and outstrips the clocks on the train in the original twin paradox scenario. That is, Einstein's relativity is contradictory and should be abandoned.

Default EINSTEIN'S SCHIZOPHRENIC THEORY

Past, present and future all equally exist (schizophrenia par excellence):

Brian Greene on The B-Theory of Time

The schizophrenic concept of time discussed by the hypnotists is a logical consequence of Einstein's 1905 false constant-speed-of-light postulate:

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. He postulated it out of logical necessity."
