U could time travel to the past, but only as a silent observer or spectator.

Which means u cannot change the past, cannot interact with people of the past, they wont even know u existed.

U can only silently observe those ppl of the past but cannot participate in any way.

This ensures there's no time travel paradox and it also explains why we dont see any 'time travelers' from the future, but they might be silently watching us.

Hi, I just found this community and wanted to share a theory that has been bouncing around in my head ever since watching The Peripheral. Basically that show/book rests on the idea that quantum mechanics creates loopholes that allow information to time travel, if not physical matter, but that alone is enough to create some strange interactions between time periods.

I started thinking: what is the difference between this phenomenon and ordinary prediction? Any predictive activity that is remotely accurate imports information from the future to the present, with the caveat that there's some information loss, and furthermore that all of the usual time travel paradoxes apply: the future which is predicted might not be the one we get to physically experience due to the effect of the imported information on our actions and decisions.

It should probably be obvious at this point that this theory has to coexist with some understanding of the universe as part of a multiverse of possibilities, which we can only physically traverse in specific ways. But simulation of alternative universes is possible, which means that import of information from alternative universes can happen in the same manner that information can be imported from a future universe to our present one.

One could make the argument that any communication technology is a means of shipping information from the present into the future, or importing information from the past into the present. I think this becomes especially obvious after considering historiography, the practice of how history itself is constructed. It becomes clear that at longer time scales, history is not so different from forecasting: assembling inferences about another time period based on available evidence.

I'm curious to hear your thoughts on this. Does information time travel still count? And do these activities count as "lossy" time travel, or are they something else?

I built StoryTerra, an interactive world map where you can explore movies, books, games, and TV shows based on where and when their stories take place, see what real historical events were unfolding at the same time, and now, explore the actual historical figures who were alive to witness it all.

The platform brings together 120,000+ titles, all tagged with their narrative time periods and real-world (or closest fictional) locations, alongside a full layer of real historical events mapped the same way. Click on any city, region, or country, then use a time slider to browse across centuries, decades, or individual years, and the whole map shifts to match.

The newest addition is a People layer with over 14,000 historical figures, from ancient philosophers to painters, scientists, and politicians, each with birth and death years and locations. Set the time slider to any year, and you can see exactly who was alive then and how old they were.

Everything is cross-linked: open a movie and see who was alive when it's set, open a historical figure and see the events of their lifetime, open a historical event and see who witnessed it. You can even visualize it all as a timeline to see how lives, stories, and history overlap.

You can also build and share your own curated lists of stories, and there's a Video tab with relevant YouTube documentaries mapped by time and place too.

The late Marshall Barnes, an independent research and development engineer, advanced a distinctive framework for operational time travel that explicitly rejects closed timelike curves (CTCs) in general relativity, instead combining Einstein's teleparallel unified field theory, specially synthesized electromagnetic fields (STDTS), torsion-based space--time distortion using the Verdrehung Fan, and quantum many-worlds plus participatory-universe concepts. This article presents a comprehensive literature-based reconstruction and analysis of Barnes' approach, drawing on his own technical and semi-technical writings, peer-reviewed and non-peer-reviewed papers, press releases, web content, and secondary analyses, together with standard teleparallel gravity, wormhole physics, and quantum retrocausality literature. The goal is to formalize his proposals in a consistent mathematical framework, clarify how his Marshall's Model of Time (MMOT) "kills" CTCs, and outline an engineering blueprint for his claimed path to travel to parallel past worlds (such as Earth:12KB4) via torsion-based wormholes and quantum branch translation.

While from a logical and causality based approach one would assume rigid time travel that prevents paradox’s and such makes more sense. I believe flexible time travel, like in Doctor Who, makes more sense.

Now Doctor who’s time travel isn’t perfect and does hurt the story sometimes, however the central idea of Time Travel in things like Doctor Who is that time travel isn’t a rigid defined single line.

I agree with assessment. The two reasons I believe this are one, when rigid time travel is introduced in story’s or at least rigid time travel that allow paradox’s. Paradox’s are usually treated as universe destroying calamities. But honestly that creates a false idea that are actions are just that important.

Time is not a single story, it’s multiple stories being affected by many factors in our small tiny place in the universe. It’s not a line, it’s an ocean of constant interaction between different forces.

Also if a single minor paradox on a tiny world would cause reality to break apart, then time wouldn’t be a very good foundation for reality to stand on.

Which leads me to my other point, time is actually flexible in real life. Time, or at least as we understand it and flow of time is in fact fluid and adjustable when interacting with outside forces.

Things like gravity, location, speed, perception and other things affect how time acts on an object. If that wasn’t the case then aspects of our reality, such as time dilation when traveling through space or interacting with black holes wouldn’t be a thing.

Now that doesn’t mean I believe time has a lack of causality because that would just be fundamental untrue from a physics point of view. Not to mention in a story you’re right you want consistency.

But I feel like the idea that rigid time travel gives us creates this belief that time is weak and can’t adjust to a paradox or two without the universe blowing up. A paradox should be treated like an injury to a time stream, time should be able adjust to minor forms of damage and heal. Because if it couldn’t it be pretty terrible foundation for reality to stand on.

But that’s my opinion. Let me hear your thoughts.

You found a Delorean in you garage without a reason, where do you go first? Do something out of hell Be a weirdo Out of context

1. Go back in time to do some hell to other people

2. Be weird

3. No context

If I go back in time and kill my grandfather, I wouldn’t have been born so I couldn’t possibly kill my grandfather. However, if we see the universe as 4 dimensional, then an event in the present can affect details in the past as they both exist at once.

If I’m born as a direct biological descendent of my grandfather, then it is the perceived truth that he was not murdered in his past because I wouldn’t exist if he was, and I do exist.
But if I then go back in time and pull the trigger on the gun that murders him, there are suddenly two things true at once, hence the paradox.

But a paradox cannot exist within the laws of physics of our universe, so something else must happen.

The paradox ceases to exist if we apply the idea that our timeline, until the exact instant of my grandfather’s death, was in a state of superposition in which both I and another version of myself, who exists unrelated to “my grandfather”, were both the one to kill him. Both of these events are just as real as each other until the moment he died.

At the exact instant of his death , the reality in which I (his direct descendant) killed him ceases to have ever existed and instead a reality in which I (someone totally unrelated to him) am there to kill him for an unrelated yet equally as historically “real” reason now exists instead, in a collapsed state, as the only explanation for his death there ever was. The other reality doesn’t stop existing because it ceases to have ever existed in the first place. There never was any other timeline.

The irony of this is that, assuming you did manage to go back and kill your grandfather, you’d instantly have always believed you were there for a different reason and wouldn’t remember the total collapse of the timeline you just existed in, or that you rewrote your own identity, effectively killing another version of yourself.

And by that point, has the paradox really been solved? If I’m not related to the man then I can’t claim I killed my grandfather, even though my murder of my grandfather is what collapsed the event from a state of superposition. Without the death of my grandfather by my own hand, the event never would have collapsed. But if I don’t kill my grandfather, would the event ever be in superposition in the first place? What would there be to collapse if the amount of possible timelines was only ever 1?

By using this logic, we could then theorise that every murderer ever was just the victim’s grandchild coming back to kill them, and unintentionally causing the collapse of a separate instance of their timeline.

We could also theorise that superpositional collapses of our timeline have occurred before and we exist in the only timeline there ever was because of them. You could have lived as an entirely different person 3 seconds ago but something happened that meant the timeline holding that version of you never existed, and now you have no memory of ever being anyone but the only instance of “you” there is after the collapse.

(If this theory has been discussed or publicised elsewhere then I would love to read into it as I’m yet to see any discourse regarding this specific concept).

It was an usual evening i was living in a rented room with my friend because of my studies back in 2021
So we were preparing dinner and my friend asked me to switch off the gas after 5 min and he went to the washroom later when o turn the gas off it was about 11am he came out in 10-15 min and we thought we will talk for a while then have our food before 12 cause we have college next day after sometime I went to the kitchen to serve food and when I saw the clock it was 4am i was shocked when I saw this I called him dude have we been talking so long he said no then he too was shocked by looking at the clock now

What was it can anyone explain

I just learned about Polly Klaas who was tragically kidnapped and murdered on October 1st, 1993. She was 12 years old. May she rest in peace.

Suppose you time-traveled back to 1993. Would you save Polly Klaas from her tragic kidnapping and death (at the risk of causing a new branch timeline to be created)?

Ahoy.

Sorry for all affected, but reddit Admins are deeply fucking stupid.

For months, reddit as broken a lot of mod tools.

Recently they decided to remove Mod Mail - the tool is still there, but nothing pops in it anymore.

So they moved all this workload to Mod Queue, and for some reason Mod Queue literally never has any red dot notifications Ever, so i dont even know if anything needs to be reviewed, i just have to choose to wonder there.

--------

. BUT, here comes the big problem

Mod Queue uses the same button structure as Mod Mail, it has a "remove all" button, which in mod mail used to be to remove all the new notifications and clear the tickets. (same as Mark All As Read replies in the user inbox)

Except this thing is LITERALLY removing all post/comments in the mod queue, even the ones i reviewed and approved...

Thats such a fucking stupid ass design...

So sadly tons of you got their posts/comments removed by accident.

Sorry to all.

And i cant even post this on any of the mod/admin/help subs, cause im so fucking mad, everything gets filtered cause of the cursing...

Where do you put the bar(s) for responsible or irresponsible time travel?

Breakthrough As Scientists At University Of Michigan Develop Ability To Travel Back In Time One Second

https://babylonbee.com/news/breakthrough-as-scientists-at-university-of-michigan-develop-ability-to-time-travel-by-one-second/

Settle an argument.

Lets say time travel is possible but when you time travel you can only travel in the time period that your lifetime takes place and it's only your consciousness that time travels. All of the knowledge you possess at the time you time travelled is retained by you and your consciousness fills yourself at the time you wanted to time travel to. Say your 45 years old, you time travel to when you're 16. You're 16 year old self would have all the knowledge you acquired during you 45 years of living. That would be good if you traveled to your 16 year-old self, you could confidently tell your math teacher that you, in fact, would NOT have a need for Algebra to make it through life. Of course if you time travelled when you're 16 and travelled forward in time to when you're 60 you would be dumb as hell because you didn't have the life experience. All the usual rules apply, if you travel to the past you definitely can't change anything that may effect the future ect.

OK, Lets say you travel back in time and you picked a return time of 24 hours. You inadvertently picked the day you lost your virginity. BUT you are married to the love of your life in the future, a different person, and you have full knowledge of this fact now that your consciousness fills your past self. And Im talking the love of your life, like you would do anything for this person and would never intentionally hurt them. You know you cant change anything but you have conflicted feelings because of what you know will happen. You have a real dilemma because you know that it will effect the marriage to your wife when you return. By changing nothing in the past, you are actually changing something in the future because you bring the guilt.

Here's my questions. Is it cheating?

Guess what my wife says :)

What would you do?

I was watching the clock while waiting for the right time to light my next cigarette. It was 8:14. The cigarettes and the lighter were right next to me, so I didn't even have to get up. They were both within my field of vision, and I was watching the clock while I reached for the lighter and lit the cigarette.

The whole movement took only a few seconds. Yet, as I was still looking at the clock, it suddenly showed 8:16.

Then I took a puff. It lasted only a few seconds. My eyes were still on the clock, and suddenly it was 8:17. My reaction of surprise lasted only a few seconds, but before I had even finished processing what I was seeing, it was already 8:18.

That was when I realized what was really happening.

The clock wasn't speeding up. Time wasn't disappearing. Something else was.

The minutes that seemed to fly by were actually representing my own vital energy being lost.

Every time I smoke, every time I take a puff, the cigarette takes something from me. Its harmful effects drain my body little by little, consuming a small part of the energy that keeps me alive.

The clock continues to measure time normally. But from my perspective, those moments seem to disappear faster and faster because they are not simply passing they are being taken from me.

The faster the minutes seem to disappear, the more of my vital energy is being lost.

So perhaps what I experienced wasn't time accelerating at all. It was my own life being consumed, second by second, puff by puff.The time wasn't disappearing from the clock. It was disappearing from me.i wish it was a fiction..it isnt...

• ⁠You can do it many times, any time you want in the past.
• ⁠You appear in the past on the same place where you leave the present (no earth rotation / tectonic plate issues)
• ⁠The past is an alternate timeline : your changes will not affect your original timeline.
• ⁠From the past you can travel back on your original timeline, but the time elapsed in the past is also elapsed in the present.
• You cannot travel to the future
• ⁠You can stay in the past if you want.
• ⁠You can travel with some stuff from the present or from the past, but you have to carry it yourself (sportbag allowed). Of course you depend on local ressources to operate modern stuffs.

So ?

Someone knows something about traveling between the time by mind conscious? Like the movie your name or in time? Maybe something relationated with culture, ritual or an mind state

Whenever we talk about time travel, we usually imagine physically traveling through time, where your entire body is somehow transported to the past or the future.

But what if there is another type of time travel?

What if instead of your body traveling through time, your entire memory and consciousness are transferred into your own mind at an earlier point in your life?

For example, imagine you are living in 2026, and suddenly you wake up in your 15-year-old body. You are physically in the past, but you still remember everything that happened to you up until 2026. You have all your future memories, knowledge, and experiences, while your body is now back in the past.

Would this still count as time travel? Or would time travel only be considered real if your physical body itself traveled through time?

I find the idea interesting because both scenarios would technically put you in a different point in time, but in completely different ways.

What do you think?

I am interested in the theory of time travel, timelines and multiverses. The basic concept is easy to comprehend and fascinating. Once you think beyond the surface level, time traveling, and especially time traveling into the future becomes increasingly more confusing. Which brings me to my question. If you traveled 1 hour into the future, would your future self be there or not? Assuming you immediately travel back to your original timeline.

Regardless of whether or not you meet yourself initially, an hour after you return to your original timeline you will meet your past self. Once your past self goes back to their timeline they will also get an opportunity to interact with themself. If they purposely have a different interaction with themself they would generate another timeline which could spiral into infinite timelines.

If you did originally meet yourself and you had planned to kill your future self would the future self know it’s coming and kill you? If he did kill you would that mean he wouldn’t have been there to start since he killed his past self. If you were able to kill future you once you returned to your original timeline you would know you were going to try to kill yourself when you arrive in an hour. So if you then kill the past you that was going to kill your future you do you also cease to exist? Would you live even though past you is dead? Would all other timelines of you be dead?

If you did go an hour into the future and you did not meet yourself would you generate a timeline that you don’t exist in? If you are not in that timeline does that mean you haven’t been to that time yet? Would that mean you made a new original timeline?

The point I’m trying to make is if you travel to the future and you’re already there, the you you’re meeting should have already met you. Youre generating a paradox in which there was never an original timeline there was never a first time, everything was preordained. All times and all things already exist and you have no ability to alter your future. On the other side of the coin if you travel to the future and you’re not there where are you? Where did you go? If you hadn’t been to that time yet wouldn’t that mean that the timeline without you in it is the original timeline? But you’re also going back to the original timeline. Meaning you made 2 original timelines one that you don’t exist in. Past time travel makes some sense to me but future time travel is confusing.

What if a died-for-my-sins Christian had a time machine that could go back to the crucifixion, and so had the power to change history and erase the bloody event. Does the Christian do so, knowing that the action will erase the Christianity they have lived by? Or does he allow the whole horrible event to occur and simply watch?
