TWIN PARADOX OR TWIN ABSURDITY?
http://homepage.ntlworld.com/academ/...elativity.html
"A more intriguing instance of this so-called 'time dilation' is the well-known 'twin paradox', where one of two twins goes for a journey and returns to find himself younger than his brother who remained behind. This case allows more scope for muddled thinking because acceleration can be brought into the discussion. Einstein maintained the greater youthfulness of the travelling twin, and admitted that it contradicts the principle of relativity, saying that acceleration must be the cause (Einstein 1918). In this he has been followed by relativists in a long controversy in many journals, much of which ably sustains the character of earlier speculations which Born describes as "monstrous" (Born 1956). Surely there are three conclusive reasons why acceleration can have nothing to do with the time dilation calculated: (i) By taking a sufficiently long journey the effects of acceleration at the start, turn-round and end could be made negligible compared with the uniform velocity time dilation which is proportional to the duration of the journey. (ii) If there is no uniform time dilation, and the effect, if any, is due to acceleration, then the use of a formula depending only on the steady velocity and its duration cannot be justified. (iii) There is, in principle, no need for acceleration. Twin A can get his velocity V before synchronizing his clock with that of twin B as he passes. He need not turn round: he could be passed by C who has a velocity V in the opposite direction, and who adjusts his clock to that of A as he passes. When C later passes B they can compare clock readings. As far as the theoretical experiment is concerned, C's clock can be considered to be A's clock returning without acceleration since, by hypothesis, all the clocks have the same rate when at rest together and change with motion in the same way independently of direction. [fn. I am indebted to Lord Halsbury for pointing this out to me.] (...) The three examples which have been dealt with above show clearly that the difficulties are not paradoxes) but genuine contradictions which follow inevitably from the principle of relativity and the physical interpretations of the Lorentz transformations. The special theory of relativity is therefore untenable as a physical theory." The following scenario will show that the travelling twin will find himself OLDER than his brother who remained behind. A long rocket passes the twin at rest, and the rocket is so long that the twin at rest will see it passing by all along. According to Einstein's special relativity, observers in the rocket see their clocks running faster than the twin at rest's clock, that is, observers in the rocket age faster than the twin at rest. At some initial moment the travelling twin, standing so far next to his brother, jumps into the rocket, joins the observers there and starts, just like them, aging faster than the twin at rest. Later the rocket stops and immediately starts moving in the opposite direction. Again, according to Einstein's special relativity, observers in the rocket, including the travelling twin, age faster than the twin at rest.

Your first hypothesis is not true. You can't make all the effects negligible compared to the uniform time dilation. One problem with your logic is that the less acceleration, the greater amount of time it takes to reverse the direction. You apparently think that if you "spread the deceleration" over the length of a long trip, you eliminate the effects of the acceleration. When you spread it out, however, you increase the time over which that "negligible" acceleration acts. So the accumulated effect of the acceleration remains the same, no matter how you spread it out. (ii) If there is no uniform time dilation, and the effect, if any, is due to acceleration, then the use of a formula depending only on the steady velocity and its duration cannot be justified. There is a uniform time dilation on the inertial observers only. The other observers aren't traveling with a uniform velocity. (iii) There is, in principle, no need for acceleration. Twin A can get his velocity V before synchronizing his clock with that of twin B as he passes. Then A can never prove to B that he didn't start moving before the actual start of the trip. He need not turn round: he could be passed by C who has a velocity V in the opposite direction, and who adjusts his clock to that of A as he passes. When C later passes B they can compare clock readings. However, C can never prove to B that he passed A at the time he did. As far as the theoretical experiment is concerned, C's clock can be considered to be A's clock returning without acceleration since, by hypothesis, all the clocks have the same rate when at rest together and change with motion in the same way independently of direction. [fn. I am indebted to Lord Halsbury for pointing this out to me.] (...) Lord Halsbury probably meant something else than what you imply. If he didn't point out the other issues, then you owe him no favors. The three examples which have been dealt with above show clearly that the difficulties are not paradoxes) but genuine contradictions which follow inevitably from the principle of relativity and the physical interpretations of the Lorentz transformations. The special theory of relativity is therefore untenable as a physical theory." GIGO. Your initial assumptions are garbage, so your conclusions are garbage. Garbage in, garbage out. The following scenario will show that the travelling twin will find himself OLDER than his brother who remained behind. A long rocket passes the twin at rest, and the rocket is so long that the twin at rest will see it passing by all along. According to Einstein's special relativity, observers in the rocket see their clocks running faster than the twin at rest's clock, that is, observers in the rocket age faster than the twin at rest. At some initial moment the travelling twin, standing so far next to his brother, jumps into the rocket, joins the observers there and starts, just like them, aging faster than the twin at rest. The twin that "jumps aboard" has to undergo a large acceleration. During the acceleration, the far away universe "appears" to speed up. The time contraction effect is nonlocal. Later the rocket stops and immediately starts moving in the opposite direction. Again, according to Einstein's special relativity, observers in the rocket, including the travelling twin, age faster than the twin at rest. You ignored the acceleration when he "jumped aboard" the craft. The time contraction effect is nonlocal. Finally the travelling twin jumps out of the rocket and rejoins his brother at rest. Who is older? The brother at rest. The traveling twin has undergone a lot more acceleration at far distances from the traveling twin. |

TWIN PARADOX OR TWIN ABSURDITY?
A high speed twin could pass a slow twin and see his his clock running
slower. The slow twin would his own clock running faster by comparison. There is no lost time just different clock rates due to different motions. Mitch Raemsch |

TWIN PARADOX OR TWIN ABSURDITY?
http://www.bartleby.com/173/23.html
Albert Einstein: "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." Is it true that "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 "? That is, do the Lorentz tranformations predict that the non- rotating clock (at the centre of the disc) runs FASTER than the rotating clock (at the edge of the disc)? If the Lorentz transformations do not predict anything like that, why is Einstein lying?

Surely there are three conclusive reasons why acceleration can have nothing to do with the time dilation calculated: (i) By taking a sufficiently long journey the effects of acceleration at the start, turn-round and end could be made negligible compared with the uniform velocity time dilation which is proportional to the duration of the journey. (ii) If there is no uniform time dilation, and the effect, if any, is due to acceleration, then the use of a formula depending only on the steady velocity and its duration cannot be justified. (iii) There is, in principle, no need for acceleration. Twin A can get his velocity V before synchronizing his clock with that of twin B as he passes. He need not turn round: he could be passed by C who has a velocity V in the opposite direction, and who adjusts his clock to that of A as he passes. When C later passes B they can compare clock readings. As far as the theoretical experiment is concerned, C's clock can be considered to be A's clock returning without acceleration since, by hypothesis, all the clocks have the same rate when at rest together and change with motion in the same way independently of direction. [fn. I am indebted to Lord Halsbury for pointing this out to me.] (...) The three examples which have been dealt with above show clearly that the difficulties are not paradoxes) but genuine contradictions which follow inevitably from the principle of relativity and the physical interpretations of the Lorentz transformations. The special theory of relativity is therefore untenable as a physical theory." The following scenario will show that the travelling twin will find himself OLDER than his brother who remained behind. A long rocket passes the twin at rest, and the rocket is so long that the twin at rest will see it passing by all along. According to Einstein's special relativity, observers in the rocket see their clocks running faster than the twin at rest's clock, that is, observers in the rocket age faster than the twin at rest. At some initial moment the travelling twin, standing so far next to his brother, jumps into the rocket, joins the observers there and starts, just like them, aging faster than the twin at rest. Later the rocket stops and immediately starts moving in the opposite direction. Again, according to Einstein's special relativity, observers in the rocket, including the travelling twin, age faster than the twin at rest. Finally the travelling twin jumps out of the rocket and rejoins his brother at rest. Who is older? Pentcho Valev |
