Time Travel is a rambling exploration of the history of time travel. It bounces around from treatments of time travel in literature to scientific papers on theoretical physics. Treating time as a 4th dimension came in vogue. However, in our world, we have only been able to move forward. Being able to move backwards seems like a logical possibility. However, why haven't we seen changes in our history? Perhaps the world is in our "best possible world". Or maybe it is just not possible to travel in time. Or perhaps it is just too hard for us to comprehend. Science Fiction stories have explored a number of possible paradoxes that could result from time travel. (What would happen if somebody went back and met themselves? Or what if they killed their ancestors or prevented them from meeting?) The book rambles around to include a history of science fiction with some significant authors (such as H.G. Wells and Heinlein.) It also looks at the treatments by physicists such as Einstein as well as the philosophy of time travel. We also explore the history of "time". (Does the consideration of the "past" separate man from other animals?) There are many interesting parts. However, there is little overwhelming thesis other than "this all has to do with movement through time."
