If we did not live in Einstein zombie world, the absurdity involved in the twin paradox and the concept of time dilation in general would be easily demonstrated simply by considering the following text of Einstein's: http://www.bartleby.com/173/23.html Albert Einstein (1879-1955). Relativity: The Special and General Theory. 1920. Chapter 23: "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. It is obvious that the same effect would be noted by an observer whom we will imagine sitting alongside his clock at the centre of the circular disc." One would verify Einstein's statements above, make a few modifications in the thought experiment (e.g. the non-rotating clock at the centre will go near the rotating periphery; there will be many rotating clocks; the diameter of the disk will be made very long which, if the linear speed of the periphery is kept constant, will make rotating clocks almost inertial) and the idiocy called "time dilation" would be rejected immediately. In Einstein zombie world the idiocy called "time dilation" may continue to destroy human rationality forever. Pentcho Valev pvalev@yahoo.com
