Nice article on the problems with time travel and travelling back in time to assassinate Hitler.
Next month sees the release of Valkyrie, a film about Claus von Stauffenberg, the man who tried to assassinate Adolph Hitler. Plenty of time travelers have had the same idea, although their plan was to kill Hitler before he enacted mass genocide. Their intentions may be noble, but the plans always seem to go awry, leaving history unchanged or even worse than when they left. We list all the ways their attempts go wrong, so you can plan your time travel accordingly.
The article that is mentioned and linked to that I enjoyed was Wikihistory by Desmond Warzel:
One of the bylaws of the International Association of Time Travelers states that you can’t kill Hitler. The problem is, everybody kills Hitler on their first trip. This leaves more experienced time travelers the onerous task of undoing the historical edits of n00bs.
