This group is for the discussion of all things to do with Time travel and Alternate Dimensions. Feel free to talk about anything, for example from Back to the Future, Sliders, Star Trek, H.G. Wells to Quantum Leap. You can focus on how these concepts are used to tell stories in fiction, or you can have discussions about the actual science behind it all, such as wormholes and Schroedinger's Cat. I have founded this group for my own interest and I hope that others will enjoy it too.
