@article{Leckenby_2017, title={Solving the Twin’s Paradox with Special Relativity}, url={https://studentjournals.anu.edu.au/index.php/cs/article/view/89}, abstractNote={<p>In this paper, we examine one of the most well known of special relativity’s apparent&nbsp;paradoxes: the twin’s paradox. It is regularly claimed that because this paradox contains&nbsp;accelerating frames that it does not belong in the domain of special relativity but must be&nbsp;solved via general relativity. We will demonstrate that this is not the case by considering&nbsp;to solutions to the paradox which only involve flat Minkowski spacetime. The first is the&nbsp;Doppler shift analysis which considers what each observer actually sees according to the&nbsp;relativistic Doppler equation which finds that both observers agree the travelling twin is&nbsp;younger. Then we solve it analytically by considering Rindler coordinates which quantify&nbsp;accelerating frames in special relativity. This will give us a numeric result which shows&nbsp;that the Earthbound twin ages the required amount during the turnaround according to&nbsp;the accelerated frame. Thus, by considering the appropriate framework, we demonstrate&nbsp;there is no paradox involved at all.</p>}, number={XII}, journal={Cross-sections}, author={Leckenby, Guy}, year={2017}, month={Sep.} }
