In this article I want to explore the idea of using time travel to affect the course of history, to right wrongs, and otherwise impose one’s own wants and wishes onto the past in order to shape the course of historical events. Righting the wrongs of the past is a common theme in time travel fiction, and it represents an attractive proposition to us: Can we save the unsavable? Supposing we had access to a classical time machine,1 could we do it? My answer is… Well, probably not.
The technical term for what the layman would consider a ‘time machine’ is a ‘Wellsian’ time machine – where a brave adventurer straps himself in, flips a switch and catapults himself forwards or backwards in time. It’s named after H.G. Wells, author of the sci-fi classic The Time Machine. ↩
