The Logic of Time Travel

2020欧洲杯晋级队伍Time travel is one of the most popular and most excitingtopics in science fiction, but comes with weird paradoxes. The followingconsiderations focus on the logical feasibility of time travel, rather than on aphysical or even a technical solution. It may seem trivial but is crucial that suspending disbelief is the key to acceptand understand fictional concepts. Anyone who reasons along the lines that "time travelmust be impossible because I could goand kill my ancestor" will probably never enjoy sciencefiction.

Since there are still six different theories on theeffects of time travel, my above considerations are not entirely satisfying.There should be something like a "Grand Unifying Theory" of timetravel, combining the single theories and thereby rationalizing the effectsshown in science fiction, even if they appear to be completely different. I wasvery glad to see that Lee Canaday had virtually the same idea. Read hisconsiderations which are one step further in this direction.
