[SOLVED] Simulteneity and other myths, maybe? In perusing Einstein's ‘Relativity’, I made a few notes for discussion. Using the moving train vs. the platform model some Einsteinian axioms get a tad oily. A mark on the train coincides with a mark on the platform just as two lights flash, both equal distances from the mark on the platform. The mark on the platform receives the light at the same instant. The mark on the train receives the light from the approaching light before the platform mark and then the light from the receding source arrives at the mark on the train. Question: Cannot the train measure times when the light arrive and conclude the train is moving? In addition, using Doppler information, cannot the exact process of the light radiation be measured and inferred and if so what has this to do with “simultaneity”? The train is motionless with respect to the platform. Then train and platform are then seen to move with respect to each other. The observers on the train notice a jerking force due to the train accelerating, yet they do not notice the persons on the platform moving in any manner. So, cannot the observers on the train know that they are moving because of the observed acceleration? May we not then determine the absolute motion between the train and platform? It seems to me that acceleration is extremely important in these kinds of events as the acceleration manifestly places one object in a higher energy state than an unaccelerated object. Similarly, an accelerated electron, for example, traveling at .9999 the speed of light has undergone massive accelerations. The mass increase can be explained by an increase in electron internal vibration states, huge vibration increases. Now if the electron at v << c can load up with energy efficiently such that relativity mass increases are not seen a until a certain critical velocity is seen cannot this be explained by the lowering of efficiency of energy transfer and storage process of the electron. In other words, as the vibration increases in scope it becomes ever more difficult to on load and store the energy with the same velocity increases seen at lower speeds? As nothing moves without acceleration the increased energy state is a constant process of nature, but the relativity ‘law’ is expressed as a simple speed limitation as (1 - v2)-1/2, which is an expression void of dynamic information and expresses a trivial and rather uninteresting oddity of nature Finally, we have a space ship moving at .9999c. We have prepared a platform of enormous length that has a number of computer data registers laid out – the data is the current time measured by the CS clock to one part in 1016 or so. As the space ship passes by it trips a switch on the platform and dumps the contents of the platform registers into registers aligned to those on board the ship. So now, we have two clocks that agree on the time. What will those on the spaceship see? And how will they react? Similarly, the platform has a bank of data registers that get similar data dumps from the space ship clicking every tick of the Cs clock that was just updated and dumped its data to the platform the next duty cycle of the Cs clock. Have we ‘violated any relativity protocols?
