  7. The Pole-Barn Paradox From Hyperphysics: http://hyperphysics.phy-astr.gsu.edu

  8. The Pole-Barn Paradox The pole-barn paradox is a famous one which must be addressed with the ideas of simultaneity in relativity. The fact that two events are simultaneous in one frame of reference does not imply that they are simultaneous as seen by an observer moving at a relativistic speed with respect to that frame.

  13. Muon Experiment: Relativistic, Muon Frame From Hyperphysics: http://hyperphysics.phy-astr.gsu.edu

  14. Muon Experiment: Comparison Time in terms of In the muon experiment, the relativistic approach yields agreement with experiment and is greatly different from the non-relativistic result. Note that the muon and ground frames do not agree on the distance and time, but they agree on the final result. One observer sees time dilation, the other sees length contraction, but neither sees both. From Hyperphysics: http://hyperphysics.phy-astr.gsu.edu

  15. Twin Paradox The story is that one of a pair of twins leaves on a high speed space journey during which he travels at a large fraction of the speed of light while the other remains on the Earth. Because of time dilation, each will see the others clock running more slowly. Which twin will be older when the traveling twin returns to Earth? Is this real? Would one twin really be younger?
