Default Einstein's Absurdities: The Traveling Twin Is Both Younger and Older

All along, the traveling twin observes his stationary brother's clock running slow, that is, he observes himself aging FASTER than his stationary brother (according to Einstein's relativity):

http://www.people.fas.harvard.edu/~djmorin/chap11.pdf
David Morin, Introduction to Classical Mechanics With Problems and Solutions, Chapter 11, p. 14: "Twin A stays on the earth, while twin B flies quickly to a distant star and back. [...] For the entire outward and return parts of the trip, B does observe A's clock running slow, but enough strangeness occurs during the turning-around period to make A end up older. Note, however, that a discussion of acceleration is not required to quantitatively understand the paradox..."

It is easy to see that the "enough strangeness" and the turning-around acceleration are just camouflage (devised by Einstein in 1918):

http://sciencechatforum.com/viewtopic.php?f=84&t=26847
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."

Conclusion: Einstein's relativity is absurd. It predicts that, according to the stationary twin, his traveling brother ends up younger. But it also predicts that, according to the traveling twin, his stationary brother ends up younger.

Actually all consequences of Einstein's 1905 false constant-speed-of-light postulate are absurd, even idiotic. One of them, length contraction, implies that unlimitedly long objects can gloriously be trapped inside unlimitedly short containers:

http://math.ucr.edu/home/baez/physic...barn_pole.html
John Baez: "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. [....] So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. [...] If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped in a compressed state inside the barn."

See, at 7:12 in the video below, how the train is trapped "in a compressed state" inside the tunnel:

"Einstein's Relativistic Train in a Tunnel Paradox: Special Relativity"

It is not difficult to realize that trapping unlimitedly long objects inside unlimitedly short containers implies infinite compressibility and drastically violates the law of conservation of energy. The trapped object, in trying to restore its original volume ("spring back to its natural shape"), would produce an enormous amount of work the energy for which comes from nowhere.

At 9:01 in the above video Sarah sees the train falling through the hole, and in order to save Einstein's relativity, the authors of the video inform the gullible world that Adam as well sees the train falling through the hole. However Adam can only see this if the train undergoes an absurd disintegration first, as shown at 9:53.

Clearly we have reductio ad absurdum: An absurd disintegration is required - it does occur in Adam's reference frame but doesn't in Sarah's. Conclusion: The underlying premise, Einstein's 1905 constant-speed-of-light postulate, is false.
