From: colp on 16 Jun 2010 02:25 The classic twin paradox is asymmetric in that one twin remains on Earth while the other leaves (i.e. only one of them accelerates and deaccelerates). In the symmetric twin paradox both twins leave Earth, setting out in opposite directions and returning to Earth at the same time. The conventional explanation for the classic twin paradox is since only one twin accelerates, the ages of the twins will be different. In the symmetric case this argument cannot be applied. The paradox of the symmetric twins is that according to special relativity (SR) each twin observes the other twin to age more slowly both on the outgoing leg and the return leg, so SR paradoxically predicts that each twin will be younger than the other when they return to Earth. The symmetric twin paradox is described more fully in the following paper: The Twin Paradox Revisited and Reformulated -- On the Possibility of Detecting Absolute Motion Authors: G. G. Nyambuya, M. D. Ngobeni http://adsabs.harvard.edu/abs/2008arXiv0804.2008N "We introduce a symmetric twin paradox whose solution can not be found within the currently accepted provinces of the STR if one adopts the currently accepted philosophy of the STR namely that it is impossible for an inertial observer to determine their state of motion."

Let me chime in. There have been no experiments showing that accelerating does indeed exhibit any time dilation. So, the classical resolution as proposed by Einstein the nitwit, the plagiarist, and the liar is totally bullshit in the first place. <shrug> > In the symmetric twin paradox both twins leave Earth, > setting out in opposite directions and returning to Earth at the same > time. Thanks, yours truly has brought this up earlier. <shrug> > The conventional explanation for the classic twin paradox is > since only one twin accelerates, the ages of the twins will be > different. In the symmetric case this argument cannot be applied. That is true. Not to mention that twins with the same acceleration profile can also coast away without any acceleration for some random time. This will enter into the time dilation in which there is absolutely no mathematical remedy or resolution for that one. <shrug> > The paradox of the symmetric twins is that according to special > relativity (SR) each twin observes the other twin to age more slowly > both on the outgoing leg > and the return leg, so SR paradoxically predicts that each twin will > be younger than > the other when they return to Earth. Don't expect the self-styled physicists to understand that one. They are indeed morons who cannot even understand or comprehend the most basic of logics. <shrug> > The symmetric twin paradox is described more fully in the following > paper: > > http://adsabs.harvard.edu/abs/2008arXiv0804.2008N > > "We introduce a symmetric twin paradox whose solution can not be found > within the currently accepted provinces of the STR if one adopts the > currently accepted philosophy of the STR namely that it is impossible > for an inertial observer to determine their state of motion." I wonder how many times this has come up in the past 100 years. Each time, it would be left under the rug. Some would call that science, but true scholars of physics would call that fraudulent. <shrug> <sigh> It helps the scientific approach if the self-styled physicists possess any intelligence to comprehend the most basic of logics. <shrug> Oh, some Einstein Dingleberries have already hypnotized themselves into believing that SR does not matter, but GR will come to rescue as that knight in white armor. That is another chapter of discussions. Anyhow, these are a bunch of delusional nincompoops who worship Einstein the nitwit, the plagiarist, and the liar as a god, and zealously gulping down servings after servings of fermented diarrhea of Einstein the nitwit, the plagiarist, and the liar. <shrug> Tragic in the academic world if you ask me. <shrug>

The truth is that, each of the twins will see the other as having aged less than they so they would not agree with their family and friends that they must be the same age. Herein we have a paradox! Who is older than who here?" Exhibit B: "If V is the speed with which the Earth bound observers (family and friends) see the twins travel at, then, according to the twins in their own respective frames of references, the Earth is receding at a speed V and the other twin is receding fromthem at a speed 2V." I note with no small amount of amusement that none of the math of special relativity was actually used in this paper. Writing a paper about how you do not understand relativity is _much_ easier than actually learning.
