Hello. I was looking for something on this page that would address the problem of Earth's motion when it comes to time travel. For instance, if I traveled forward or backward in time one minute to my current location, which is a spot currently occupied by the crust of the Earth, I would presumably then be at a point inside the Earth or in outer space because while I have not moved, the Earth has moved. When there is discussion of going back to the far past or far future, I always wonder how travel to that distant location lightyears away from Earth's present position is accomplished. The Earth moves, so you have to get to where the Earth was at or will be if you want to time travel somewhere beside the cold void of space. Maybe time travelers have done it, but they accidentally found themselves in outer space since the Earth moved. Is there anything on this page or in the literature that discusses this locational displacement problem? I would hate to be the one who creates time travel only to accidently time travel to one's present location one minute later, which is now a spot in the Earth's core or in deep space since the Earth has moved.

I don't understand why there are two top-level sections for addressing the concept in physics: "Time travel in physics" and "Forward time travel in physics". Surely the latter is a subtopic of the former? Or if they are kept separate, shouldn't the former be "Backward time travel in physics" for symmetry? Reading the former section with all of its uncertainty and speculation – when we know that forward time travel is possible – was confusing until I found the latter section tucked below it as if an afterthought.- Jason A.

Right now this redirects here and never had a separate article on English Wikipedia (I noticed it does on pl wiki, and several others; here's the wikidata entry [1]). And here's an interesting source: [2]. I haven't done much lit review but there are plenty of uses of the term, some pretty close to the basic concept (consider [3], [4], [5], [6], [7], [8]... the term is actually used a lot in physics!), but this one is decent, and here could be an interesting article on a relatively major topic related to fiction (and even science??) that could be created... would anyone be interested in working on it? The topic has a stand-alone entry in the SF encyclopedia: [9], separate from their entry on time travel. Ping User:Haleth, User:Toughpigs - this time not re deletion/rescuing, but maybe we can try to write a new entry together for a change? Any sources you could throw at me here would be appreciated. (Btw, I checked and the concept sadly does not seem to have a stand-alone entry in The Greenwood Encyclopedia of Science Fiction and Fantasy: Themes, Works, and Wonders nor The Mammoth Encyclopedia of Science Fiction). -- Piotr Konieczny aka Prokonsul Piotrus| reply here 03:12, 24 February 2021 (UTC)
This section needs more clarity and references. The paragraph "Presentism in classical spacetime deems that only the present exists; this is not reconcilable with special relativity, shown in the following example: " merely asserts the incompatibility of presentism with special relativity. But that assertion is the point of contention. I find the phrase "Presentism in classical spacetime" to be ambiguous. It needs some definition. Also, the argument for eternalism appears to be a form of that of Putnam, H. 1995. Time and Physical Geometry. In Mathematics, Matter and Method, Philosophical Papers, Vol. I., 2nd edition, pp. 198-205. Cambridge University Press. I suggest that reference be added. (Personally I find Putnam's argument unpersuasive and flawed). Theophilus71 ( talk) 18:15, 15 January 2022 (UTC)
the science fiction template should not be on this page as this would be real. — Preceding unsigned comment added by 2601:18D:4700:2D30:7036:813F:CCBD:B905 ( talk) 21:01, 12 October 2022 (UTC)
The first known person in human history, at least for now, who thought about time travel to the past, (and not to the future!) is the well-known British poet Lord Byron. In his play "Cain" from 1821, . In this play, Cain's time journey to the far past of the Earth is described. As far as is known no one in human history had thought of such a thing before Lord Byron. 79.180.18.23 ( talk) 02:28, 18 March 2023 (UTC)
