Back to the Future and Forward to the Past

n his new book Time Travel: A History, James Gleick presents a valuable literary history of the idea of time travel while also highlighting the various paradoxes associated with the topic. Time travel too often can be considered an unserious aspect of physics and the subject only of speculative fiction. By writing this book, Gleick indicates that the paradoxes inherent in the concept should be taken seriously because solving those problems could lead to a more consistent scaffold of understanding for the role of time in theoretical physics. Gleick’s book creates an important history for the concept of time travel and makes the paradoxes clear. The author seems to have written the book in part to bring attention to the topic of time travel in the hopes that other thinkers will take the subject seriously and look for solutions to the paradoxes.

To begin, H.G. Wells still does not get enough credit for his genius. The man single-handedly invented the discipline of World History, pioneered the “invading aliens” genre, and can be fairly credited with introducing the concept of scientific time travel literature. Gleick indicates that the widespread use of trains made humans realize that their relationship to distance differed depending on speed—it was only a matter of thinking about time before someone realized that our relationship to time also differed depending on speed. Gleick writes that Wells did not bother himself much with the physics as “He was just trying to gin up a plausible-sounding plot device for a piece of fantastic storytelling” (p. 4). Yet it is possible to see how the creativity of both Wells and Einstein branched off from the same concepts.
