A trip to the end of the universe and the twin "paradox"
Thomas Müller, Andreas King, Daria Adis
In principal, the twin paradox offers the possibility to go on a trip to the center of our galaxy or even to the end of our universe within life time. In order to be a most comfortable journey the voyaging twin accelerates with one earth gravity. We developed some Java applets to visualize what both twins could really measure, namely time signals and light coming from the surrounding sky.
