    "abstract": "In principle, the twin paradox offers the possibility to go on a trip to the\ncenter of our galaxy or even to the end of our universe within life time. In\norder to be a most comfortable journey the voyaging twin accelerates with\nEarth\u0027s gravity. We developed some Java applets to visualize what both twins\ncould really measure, namely time signals and light coming from the surrounding\nsky.",
