This is one of my favourite documentaries and I've seen it before (about five times!)
Time travel is a pet subject of mine, I have written a teenage novel involving it.(as of yet unpublished so I don't want to give anything away!) - However I will say the heroine of the story has the biological ability to time travel and I got totally swept away with the concept and it really got me thinking a lot about the theoretical possibilities. In my story I talk about the theory of relativity but I talk about stuff like the speed of thought and describe scenes where she has moved through time and also what happens when she freezes time - which really would be impossible (or would it?) - Thanks ironwood you made my day!
