Christina, that was interesting show on the concepts of time. I now understand Einstein better than I ever did before and why he's such a physics god. I don't think it helps with my newest time-travel fic. Plus that whole time / space concept is making me

I going to stick with the Wells / Brown (BttF) version of time-travel. Build a good machine and you can go anywhere! Sorry, anywhere & anywhen! (Maybe that's what they mean by time & space?)
