Talk:Temporal paradox

message: This reads like someone got high and felt like editing. Honestly, how can an article be taken seriously when the entire thing is written in the 2nd person while the third person is hitting the joint? —Preceding unsigned comment added by 208.103.137.34 (talk • contribs) 09:35, 3 February 2008 (UTC)
replies: text: This article is based primarily on references to media, popular culture, and unverifiable assumptions.  It seems better suited for a site dedicated to media references.  This page should be dedicated to the facts surrounding scientific research on the temporal paradox and not be a promotion for modern media.  Just one example—the Multiple universe hypothesis was not created by an unverified author of a single Dragon Ball episode.  It was created by William James in 1895.  Are we to credit the entire series as an example of a literary device catalogued so comprehensively at TV Tropes?  How do you verify the metrics for fan speculation?  Almost all of this page should either be deleted or researched to include accredited experts on the individual topics.  Otherwise, it should be moved to a broader literary device article.—StonedPerson (talk • contribs) 04:00, 30 July 2011 (UTC)

thread_title:   Excessive Focus on Modern Media 

message: Hey folks, I found an article on the Timeline Protection Hypothesis, which was suggested by Steven Hawking a few years back.  He calls it the "Chronology protection conjecture", but it seems to describe pretty much the same thing as our own "Timeline protection hypothesis"  Nevertheless, we may wish to make our own reference to the T. P. Hypothesis link to the above article.   ZZYZX 07:38, 18 July 2007 (UTC)

message: I think that the novel Night Watch might be a further example of the Temporal Merging Hypothesis, but I am not entirely sure and even if I was, I can't seem to explain how it is understandably.--SurrealWarrior (talk) 20:00, 11 September 2008 (UTC)
thread_title:  Night Watch 

message: Im not sure if this is an established theory or if it is the correct name for it if it is, but the idea is that one cannot change the past since the past has already happened. Wouldn't this make it impossible to be present in the past? Since the time-travelling you were not there when this happened? Or make it impossible to view the past since you didn't witness this event in this manner or during current circumstances? And even if one could circumvent that, your presence would inevitbly change the past on some other miniscule level (like the displacement of a microscopic entity)? 
Oh, and another theory i have issues with is that if someone travels back in time and touches a past self it would trigger some kind of paradox. The deal being that matter cant be in physical contact with itself in this sense. Wouldn't this result in absolutely nothing (other than the fact that you just did it)? If you can do it, then it would acctualy be physically possible and the universe would NOT explode? If you are doing something that is absolutely impossible by the laws of physics, then it would mean that the laws of physics were wrong.

replies: text: Isn't there already an overview of all the temporal paradoxes in the main time travel article? If the overview there covers everything, and the individual paradoxes have their own articles, then there doesn't seem to be a lot of point to having this page.

thread_title:  Merge with grandfather paradox 

message: I removed that section for the following reasons:
*It appears to have been edited solely by the person who created the hypothesis.
*Lacks any references.
*Original research is not allowed in wikipedia (and the writer seems to lack applicable credentials anyways).
*The idea is very unclear as presented, and sounds like pseudo science.
*The only relevant results I found on google for this phrase are related directly to this wikipedia entry.  —Preceding unsigned comment added by JoshuaPearce (talk • contribs) 08:22, 10 May 2011 (UTC)

thread_title:  Removed "Joule's Animation Time hypothesis" 

message: It seems that most of the theories in the article are ones postulated by various comic books, films/TV shows, video games modern fiction, etc. A lot of the theories rely upon ulterior entities, or an "intelligent" universe, which serve as protectors of timelines. While these theories are not necessarily incorrect, they are based purely on speculation rather than practical theories or empirical observation. Perhaps they should be moved to their own article? Either way, theories such as "Time Corruption"/"Doomed Timeline"/ (in which the universe just magically "deletes"/"crashes" itself as a result of a timeline change), "Self Healing Hypothesis" (postulates that the Universe would "heal" itself, implying that the universe is capable of intelligent, organism responses to timeline modifications), "Temporal merging hypothesis" (for some reason, time travelers modifications would "merge" with each other, though no mechanism is which this could occur is even speculated upon), etc, etc, should not be in an article about the concept of temporal paradoxes. Essentially, this article has turned into "Temporal Paradoxes in Popular Culture" rather than a theoretical inspection of temporal paradoxes. The other problem is that this article is not actually about temporal paradoxes themselves, but their solutions. It barely even mentions any paradoxes, and has ONE main section labeled "Solutions". Um, solutions to what? LiamSP (talk) 01:56, 11 June 2012 (UTC)
replies: text: I see what you are saying, but it does not seem to be totally at lost to theories without such fictional origins. The Novikov self-consistency principle was from an esteemed physicist, for example. Also, many of the theories being presented in the article may be best represented by referencing works of fiction, as that is the the best way to explain them to a layman. But I don't think changing the name to "Temporal Paradoxes in Popular Culture" is apt. It would be odd to have a "Temporal Paradoxes in Popular Culture" article but no "Temporal Paradox" article, if it were to be moved to that new title.

thread_title:  Terrible Article Considering It's Title 

message: Looks like someone has just strung together a bunch of synopses of science fiction stories. While no doubt science fiction writers can tell a good tale, there's nothing grounded in science here - perhaps the article should be called "Temporal Paradoxes in Fiction"  — Preceding unsigned comment added by 68.51.66.32 (talk) 21:06, 27 June 2012 (UTC)
replies: text: FYI and as a general statement to all involved, the definition of "Science Fiction" directly contradicts this statement.  The very definition of "Science Fiction" includes the idea that the fictional universe of the story is governed by the scientific, "known laws" of the universe, hence the word "Science Fiction". As a secondary, "outlier" sub-genre of Science Fiction is one in which the known laws of the universe are deliberately altered, or amended by the author.  "What if" gravity wasn't, or Einstein's theory wasn't, etc... Similar to the idea of "What if the South had won the Civil War."  The definition of Science Fiction is based on the idea that there are either "known laws", or "hypothetically known laws".  Most of the classic science fiction writers were actual scientists, with doctorates in science, etc...  This is in direct contrast to the literary class "Science Fantasy" which basically means "anything goes", including time travel.  Many Science Fiction literary works deliberately explored the time-travel paradox, where the author attempted to reconcile the idea of time travel with the time travel paradox, but all of those works explicitly adhered to the "known laws of the universe".  This is an important distinction to make, as many people today describe works like Star Trek as "science fiction", despite the fact that several (many?) episodes ignore the time travel paradox (someone goes back in time, "does something", and comes back to their starting point in the future and nothing has changed, which is a scientific impossibility once you start thinking about causality.  You can't go back in time, and kill your grandfather, because if you did, you wouldn't be there to go back in time to kill your grandfather.  The obvious logic of this is an important thing to explicitly mention in this Article, since many people think "Star Trek" is Science Fiction, and not Science Fantasy.  This, despite being absolutely true, is also in at variance to popular belief and opinion, so finding, and then getting consensus to include RS that describes this could be difficult.  I am willing to work on this Article to bring this information into the Article, but am unwilling to do it alone.  Is anyone else in agreement with my thesis, and is willing to work on this with me?Tym Whittier (talk) 15:33, 23 May 2019 (UTC)

thread_title: Silly, Silly, Silly

message: After looking through the theories, I noted that Back to the Future II actually more clossely resembles the Branch theory, rather than the Time corruption theory.  At first, I had added it to the branch theory mini-section, but then noticed it was mentioned in the time corruption theory.  Before I change it, I'd like to make sure I'm not missing something, as this is what I would have put in the section relating to branching:
Another example of this theory is in the Back to the Future series of movies.  In Back to the Future II when Marty McFly consults with Doc about why this future is completely different from the one he always knew, Doc explains on a chalkboard that time had branched off from the original timeline, due to a change in the past that old Biff caused.
The reason why I don't think this belongs in the corruption theory is that there really are literal branches, and alternate timelines in the series.  In my opinion, the only thing that even gives an indication of the "butterfly effect" is the fact that the effects of changing the past are not immediate.  Is that why this was put there, instead?

thread_title: merge sections?

message: What if, by reversing time and entering the past, you don't replace your past self at that instant, but insted turn up an the past as a third person, exactly like yourself in the future (technically, the present). So in the first case, let us assume your past and present self never meet during the course of your time travel. That means in the past, it is possible that your future self would have been there, but you just didn't see him. In the second case, your present and past selves meet each other. That means that in the past, you would've seen an older version of yourself at some point in time (which happens to be at the exact same time you travelled back to from the future), but you may not have recognised your future self at that time, because your past self doesn't know that time travel will be invented in the future. So if you find someone who looks a lot like you, and is older - it's your lucky day!

thread_title:  This article is an embarrassment 

message: "If the specified note said to go back into time, stop the assassination, copy this note, and place it in the same spot it originally was, one might be able to intentionally stop the assassination."
Unless there is a work of fiction to cite where this was done, then this should be removed, because it's logically impossible. If a time traveler prevents JFK's assassination, then that event is not in the history books for anyone in the future to decide to assign a time traveler a mission to prevent the assassination. That's basically the whole point of the theory.
:Actually, the point is that in this case the cause of the time travel would be the note rather than the assassination itself. Essentially resolving the Grandfather Paradox by creating a Predestination Paradox (although the note in question would likely need to be very persuasive). I'm certain I've read examples of this, but I cannot recall a particular title at this time. As I collect Time Travel books it would take some time to locate one of them, however if I should run across one I will post back. And, incidentally, the lack of a fiction story to reference does not, in and of itself, negate a theory. Just saying. AeonsAblaze (talk) 03:07, 30 January 2015 (UTC)

The first sentence of the other section, "information loop" is probably supported by one of the citations above as well; but I've added a cn tag to it.
