If time travel existed, he said, then we would have been visited by tourists from the future. Since we see no tourists from the future, ergo: time travel is not possible. Because of the enormous amount of work done by theoretical physicists within the last 5 years or so, Hawking has since changed his mind, and now believes that time travel is ...
Feb 17, 2000 · Time Travel and Modern Physics. First published Thu Feb 17, 2000; substantive revision Wed Dec 23, 2009. Time travel has been a staple of science fiction. With the advent of general relativity it has been entertained by serious physicists. But, especially in the philosophy literature, there have been arguments that time travel is inherently ...

Oct 06, 2021 · Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.
Answer (1 of 2): The only valid theory about Time Travel comes in a solution from the Einstein Field Equations: Closed Timelike Curves (CTCs) Hypothesised by Kurt Gödel in 1949, these are results which pop up in a few solutions (the original Godel metric, Tipler cylinder and traversible wormhole...
Jul 07, 2021 · There are other scientific theories about time travel, including some weird physics that arise around wormholes, black holes and string theory. For the most part, though, time travel remains the ...
