The Reason there are no time travellers is that they died in the vacuum of space.
My point being is that the whole universe is moving.
The earth is moving around the Sun, The Solar System is moving within the galaxy and the galaxy is moving in an ever expanding universe. If someone was to time travel but was not able to teleport to the exact point the earth was at that time you would end up in deep space millions of miles away. Example it is August 2027 and I traveled to January 2027 but stayed in the exact same location when I emerged, the earth would be on the other side of the sun from my position.

Chicken Egg Dilemma
Need suggestions on whether opening chapter should be in 2121, 1988, or at reading of will in 2018
Here is the timeline I have in mind
Millionaires wife has rare incurable disease in 1988
He wonders if at some future time (1) cure will be discovered and (2) technology will exist to transmit inanimate objects back in time to a specific place and time
He determines to make that happen
Within a month from that determination, he finds a prescription bottle with his wife’s name on it and directions for use. The cure is in his hands
He takes the following steps (as a minimum)
Gets his wife to take the medicine - she and he have a good life together
Establishes a well-funded company called Time Corp that promotes time travel technology and monitors future medical research developments
Writes his will so that the company will continue to function for as long as it takes knowing that all will work out if nobody messes things up
He dies and his will makes almost all of his heirs happy. His executor is appointed and accepts the challenge to move his agenda along
One very intelligent family member sees an opportunity to get a bigger share of the fortune left by the millionaire
Thanks largely to a savvy ex-military daughter-in-law, the family lawyers, some awesome PIs, and a couple of really capable grandsons, the plot fails and the grandfathers dream materializes
In 2121AD Time Corp puts the prescription bottle in a container, throws the switch, and MISSION ACCOMPLISHED

Loki’s timelines, Endgame’s time travel and the Time Stone look contradictory. I treated them as one physics problem and built a consistent framework
I’m a physicist, and it took me a while to reconcile MCU time travel because Loki, Endgame and the Time Stone seem to contradict each other. Not because fictional time travel needs to obey real physics, but because they all get called “time travel” even though they are doing different things. In the process, I think I developed a fully consistent model of MCU multiverse time mechanics
The whole model (3 parts):
- Quantum Realm: changing the visited past creates another branching timeline.
- Time Stone: changing the past was already determined in the timeline. A timeline is the sequence of configurations of matter and energy in the universe, ordered by what the Time Stone itself experiences. No branch is created.
- TVA / Loki: acts on the whole tree of timelines from a higher-level TVA meta-time.
I’ve seen a lot of people reconcile pieces of this before, especially Endgame branching and the TVA. What I’ve done is take the explanations that can coexist, discard the ones that clash, and add a few pieces where the MCU leaves gaps. The result is one framework with three different operations on time.
1. Quantum Realm time travel: changing the past creates a branch
The grandfather paradox is the easiest way to show why branching is useful. If you travel back and kill your grandfather before you were born, the usual contradiction is obvious: if you were never born, who travelled back to kill him? In a branching framework there is no paradox. You came from the original timeline where your grandfather survived and you were born. Killing him creates a new branching timeline where he dies and the version of you native to that branching timeline is never born. The traveller is unaffected because the timeline they came from still exists, with an unkilled grandfather.
[See Image 1 Top: simple grandfather-paradox branching diagram]
Once that rule is in place, Endgame becomes much easier to read. Removing an Infinity Stone from the visited past immediately creates another branching timeline where the Stones have been removed. If you trace backwards along the Avengers’ original timeline, the Stones were never removed there at all. That is still the parent history (original timeline) they came from. Steve returns each Stone to the exact instant it was taken, so the Stone-less branch is prevented from forming, and the ancient one is happy.
The weirder consequence is 2014 Thanos. He leaves 2014, travels to 2023 and dies there. That should create a branching timeline where Thanos simply disappears in 2014. Steve still returns the Stones, so that timeline has all six Infinity Stones, but its Thanos is dead and the later Infinity War should never happen there. Before Loki, the TVA could prune that timeline if it fell outside the histories He Who Remains permitted. After Loki, branches are allowed to persist. Whether Marvel ever shows that exact no-Thanos timeline is another question, but it follows from the branching rule. But this is explained more in 3. below.
[See Image 2: existing Endgame branch / Stone-return timeline schematic]
> There is an obvious similarity here to the many-worlds interpretation of quantum mechanics: different realised outcomes from wavefunction collapse can exist on different branches instead of one outcome having to overwrite the others. That is the physical picture I am borrowing for the branching structure.
2. The Time Stone: changing the past was already determined to happen inside the timeline
The Time Stone is doing something different. Strange rewinding the apple does not need another timeline. The main definition I use from here onward is:
> A timeline is a sequence of configurations of matter and energy in the universe, ordered by what is observed / experienced by the Time Stone itself.
That is the reference parameter for the timeline whenever the Stone is involved.
memory of the reversed object BEFORE timestone reversal
A → B → C
memory of the reversed object AFTER timestone reversal
A → B′ → C′ → D
experience/memory of the TIMESTONE ITSELF (the only consistent definition of timeline)
A → B → C → rewind → B′ → C′ → D
[See Image 1 Bottom: Time Stone-parameterized timeline]
That whole last sequence is what the timeline encodes, where each letter is the configuration of matter and energy in the universe. Strange deciding to use the Stone, the reversal itself, and whatever happens afterwards were all already part of what happens in that timeline. No branching occurs.
This is why ordinary Earth-time is not enough to parameterise the timeline once the Stone starts reversing things. If Strange reverses an apple while he and the Stone remain outside the reversal, Strange remembers seeing the apple rewind while the apple returns to an earlier physical state. If he reverses a larger region, the matter inside that region is reversed too, including brains, memories and clocks. The people inside therefore do not remember the interval that has been undone, while Strange does.
> The only invariant reference here is the Time Stone itself, because anyone can be the person using it. The user can sit inside or outside the region being reversed, different observers can remember different things, and ordinary clocks can themselves be reversed. The Stone is the object whose experienced ordering remains available as the reference, with each point in that ordering corresponding to one complete matter-and-energy configuration of the universe. In shorthand:
timeline = X(τ_TS)
where X is the complete matter-and-energy configuration of the universe and τ_TS is the ordering observed / experienced by the Time Stone itself.
The closest physics analogy for the deterministic part is superdeterminism, in the sense that the intervention itself is part of the full physical history rather than an independent choice arriving from outside it. The decision to use the Stone, the Stone being used, the rewind and the resulting state are all contained in the same complete history. Changing the past was always determined to happen inside the timeline.
This is only really significant inside that universe/timeline. From the level of the Multiverse, the structure of timelines has not changed (as it was completely determined). The Time Stone reversal was always part of that timeline and was always predetermined within its history. The drawer of useless Infinity Stones at the TVA fits this nicely: the Stones can have enormous control over the physics inside a universe without controlling the higher-level structure that contains the universes.
Summarising before final section:
> Quantum Realm: changing the visited past creates another timeline.
> Time Stone: changing the past was already determined in the timeline; the timeline is the sequence of matter-and-energy configurations ordered by what the Time Stone itself experiences. No branch is created.
3. Loki and the TVA: meta-time
Quick reminder of the Loki setup: before Loki, He Who Remains used the TVA to maintain the Sacred Timeline, a controlled set of permitted timelines woven mainly around the Earth-616 / Avengers history. Branches were pruned when they led outside the structure he wanted, especially if they could produce rival Kangs. In this framework, that also means no persistent Fantastic Four or X-Men timelines. After Loki Season 2, Loki replaces that pruning regime and allows the branches to grow and persist.
> “Before Loki” and “after Loki” are therefore not dates inside Earth-616. They are two different configurations of the whole branching system, measured at the TVA level.
For an intuitive picture, lay a tree on its side. The trunk is a timeline, left-to-right is ordinary Earth-time, and branches can grow from any point along it. Now stand outside the tree with some shears. You can cut a branch growing from what people inside the timeline call 1200, then one from 2012, then one from 3000. Those are completely different dates in Earth-time, but from your perspective you just performed three actions one after another.
So there are two parameters: position along the tree is local timeline-time; the time experienced by the person manipulating the whole tree is TVA meta-time.
[See Image 3: TVA meta-time diagram]
> That is why “before Loki” and “after Loki” are categorical states of the Multiverse, not sequential dates when viewed from inside a universe. Before Loki, in TVA meta-time, a Fantastic Four timeline is not part of the permitted Multiverse because He Who Remains prunes the branches that would allow that history to persist. After Loki, that timeline can exist with its entire local history intact.
This produces a strange but important consequence: from the perspective of beings living inside Earth-616, the Fantastic Four timeline can be said to have never existed under the “before Loki” configuration, yet to have always existed under the “after Loki” configuration. There is no single Earth-616 date when it suddenly appears. “Before/after” refers to TVA meta-time; “always” refers to local time inside the timeline itself.
One slight lie in the tree analogy: I called the x-axis “Earth-time” because that is the easiest way to picture it. That works only while the Time Stone is not reversing Earth itself. From section 2, the rigorous x-axis is actually the sequence of complete matter-and-energy configurations ordered by what the Time Stone itself observes / experiences, τ_TS.
Marvel also seems to roughly align the “before Loki” era with stories released before Loki in 2021, and the “after Loki” era with the Multiverse-heavy stories that followed. So my best guess is that Endgame still belongs to the old TVA-controlled setup, while No Way Home, Multiverse of Madness, Deadpool & Wolverine, Fantastic Four etc. are being shown to us after the branching Multiverse has been opened.
> Personal Thoughts: I like what Marvel did here because it gives a clean way to reconcile the older movie continuities. Raimi’s Spider-Man and the Amazing Spider-Man films do not need to be rewritten into Earth-616. No Way Home can simply establish that those complete histories exist on other timelines in the same Multiverse. The same logic lets a Fantastic Four universe have its own full history without needing an explanation for why those characters never appeared in Endgame.
Reposting this from my old account
Summary
The full object is a tree where every timeline path is a predetermined sequence of matter-and-energy configurations, ordered by what the Time Stone itself experiences. Sub-branches can split from any point along any existing path, either naturally or because Quantum Realm time travel changes something.
> This is basically where “free will” sits in the MCU framework. Every individual timeline already has a determined past and future, but an observer living inside it does not know which future branch they are going to move into. From inside the universe, the future still feels open; from the level of the completed timeline tree, every branch already has its own fixed history.
That is the time framework I am using for the rest of the MCU model. The next post I will be making is regarding space: once where universes, realities, branching timelines, dimensions, realms and planes become a containment/connectivity problem rather than another version of “parallel universe”.
TL;DR
- A timeline, X(τ_TS): a sequence of complete matter-and-energy configurations in the universe, ordered by what is observed / experienced by the Time Stone itself.
- The Time Stone: reverses the physical configuration in the universe while remaining entirely inside one predetermined timeline. No branching occurs.
- Quantum Realm time travel: an intervention can split off a new timeline from a point in that sequence.
- Natural branching: new timelines can split from the sequence without a time traveller causing it.
- The TVA / Loki: operates on the whole tree of timelines from TVA meta-time.
- Free Will: not knowing which branch you will move into
If anyone can think of an MCU example, not comics, that doesn’t fit this, comment the specific scene. Would be cool to see if we can make this properly rigorous together.

You wake up at 6am EST on September 11, 2001. How do you stop 9/11?
You’re exactly where your past self was on that day, but you retain all of your memories and knowledge that you have right now. Consciousness time travel (like Wolverine in Days of Future Past). How do you prevent the planes from hitting the Twin Towers? Bonus if you somehow can stop the attack on the Pentagon or Flight 93 from crashing.

geo engineering heat dome=industrail heaters
what is a heat wave? hot as air pretty much steam but where it come from anchor man try explain try make it sound scientific . but lets put common sense to it . this massive amount of heat just come out the earth? really only comes out summer time like earth just farted some hot air coming your way but only doing certain time of the year. ok if you believe that what triggers it? they say see sun gets real hot come back to what makes the sun so hot and unbearable now its not the sun its reflective substance like foil paper up there reflected sun light back to earth to increase the heat. now back to the heat wave. you know how regular heater works. push out hot air straight forward right. well think big scale. big as heater way up there pushing out hot air on top of the reflective sunlight creating a short hell on earth but what they really doing high pressure and low pressure or cold air and hot air meet what happens thunderstorms . now lets continue using our common sense not listen those bucket heads think many thunderstorms daily what would that do wouldnt that push more cold air from the north as the seasons change supposingly . keep up with the timeline. make it hot possible middle of the day mid 90's or so then the storms pop out no where so call around 3-6pm to cool it down at night. every day. this month. keep track its either goin rain or cloudy enough cover the sun same time all this month. watch for yourself they doing in front of you. and you pay close enough attention the clouds that pop up follow the trail dont it look like its coming from the ground far off? now you know and knowing is half the battle.....go joe

How does light-speed travel in stories like “Starwars” and “Star Trek” affect the passage of time at the destination?
reddit.comu/Cptawesome23 — 2 days ago
I've been thinking about Mandela Effects as evidence of a patchable system. Wrote a book about what that implies for how to actually play.
What makes Mandela Effects genuinely interesting to me is that underneath all of the memories and glitches, there's a question that if the past can shift, the system isn't fixed. If the system isn't fixed, it patches. If it patches, there's a version of you running on a strategy guide that no longer matches the current build.
I've spent a lot of time thinking about how the 'system' patches itself and how we ourselves could patch or update our own current build. There must be a way to actually win at this game, some how. Because even setting aside whether specific memories are real, it seems most of us are playing a strategy that was written for a version of the game that isn't running anymore. Not to mention we were thrown into this world and birthed, for complete unknown reasons to us, and not given any type of guide whatsoever as to how to get through this life.
I wrote a book about what it means to play a system that patches continuously and how to build a character that survives the updates. Ultimately it's about what winning could even mean if we are quite truly living in some type of game.
It's called The Game of Earth: A No-Bullshit Player's Guide by ZD Fanawe.
The book doesn't require believing the Mandela Effects are literal. It uses the patchable-system frame because it's genuinely what our experience keeps showing us over and over again, which is that the rules update and yet we are all running on code that wasn't updated itself. And no one has shown us how to exit any of this or how to win at it (if that's even possible. which I try to outline in the book, that it is)

Bypass Time Travel problems and become a god
When I was taking a dump at 3am, I've got an idea that makes a lot of sense, but is not explored much. Once we will hit a wall, and discovering new things will take more and more time and effort, and I found a way to bypass it........ If a civilization was able to reach the technological advancment of creating a realistic simulation of a universe, it would be the most powerful creation of everything that is and isn't, because it is the only way to bypass the time travel problem. We can travel to the future by either being near the black hole, or moving at an incredible speed....but If we got there, we cannot return back and there's no way to actually apply the technology from the future in the past because of it.......one way to bypass it, is by creating a realistic simulation of a universe that would be sped up with computational power, meaning that for example a bilion years in the simulated universe would pass in only a few minutes in the real one, and the most powerful way to use it is to simulate it to the point where those simulated civilization surpass you technologically and just use their findings, if we are simulated, it means we are coded and there is a database somewhere, where AI could filter only important things through it, meaning that the fastest way to technologically improve is let simulated universe run faster and copy the technology from the civilizations that are more advancened because they had more time......and this could be done again and again, until there's nothing to know more....

Is present even real!?
The present is so small that you can say it doesn't even exist The present is only a Planck time As soon as the Planck time passes we are already in the future we were thinking of during the previous Planck time and only that Past and future do not exist in reality The past of course no longer exists it has already happened The future of course does not exist because it is the future it is only mental it hasn't even been created yet And as soon as we go to the future meaning as soon as the Planck time passes the future will have already become the present Nothing exists If time does not exist space will not exist nothing But what will happen if we somehow remove time from the entire universe Would the universe have ever existed Because if the past is physical meaning if the past exists and we just can't go there and we remove time the universe never existed because everything will be erased On the other hand if the past was something that existed and no longer exists then it would still exist in mental thought Meaning if an intelligent life form leaves our universe before time is destroyed it will remember that its universe existed But if the past is physical as we said before it will be erased instantly

State of the Art for time travel
Is everyone on board that the main hurdle a person has in experiencing time travel is psychological?
Many people fall asleep and experience a jump in time. Even if you get a surgery you are passed out, under the control of a powerful drug and health care system.
My thought is: limit it to just Reddit. when would you travel to in Reddit’s history and what would you type?

A time travel modem that doesn’t have any paradox’s
I have been thinking of this model for some time and I honestly liked it and don’t know if I seen anything like this before.
A few rules before diving on how it works.
- Everything is deterministic.
- The past doesn’t change and history can not be altered.
- Every universe has its own consistent historical rules.
- No bootstrap paradoxes. Every event has a a beginning however there could be infinite chains after that first event.
Let’s say we are in T:2026 ( time 2026) in U:1 (universe 1)
And I build a Time Machine and decide to go back to T:1500 and feed a kitten then go back to T:2026.
If my universe (U:1) has this event that already happened in the past, a mysterious man feeding a kitten then disappears then when I time travel I don’t actually change the past, I fulfill it. Every event that happened has already happened and I am merely just a traveler that is fulfilling what he did in the past.
Imagine a situation where I want to go back in time but the event of me feeding a cat in 1500 never actually happened, I’d essentially be rewriting history. So what happens is that when I go from T:2026 to T:1500, I’d be unknowingly leaving U:1 and going into a universe where that event is already part of its history, a kitten being feed by me in T:1500, let’s call this universe U:2.
For me, universe hopping exists when an event that is incompatible with its universe’s history exists. It sends me into a universe where that event already happened.
An interesting thing is that if I go back to T:2026 I could actually go back to T:2026 in U:2 not U:1 (if going back to T:2026 in U:2 is compatible with its history) and I would meet U:2 version of me, So There would be two instances of me. One from U:1 and one for U:2.
I can not control universe hopping, it only exists to accommodate with me traveling into a universe where my time traveling move already exists.
Let’s imagine a situation where people in U:2 tell the second version of me, let’s call them P2 ( short for person) that you time traveled into 1500 and fed a cat. P2 would be confused and say no I didn’t time travel into 1500 to feed a cat. This would be a paradox but in reality it isn’t. The person who went back in time to feed the kitten originated from another universe. U:1. So it’s a different universal version of P.
We established that P1 which is me is now in U2. And imagine P2 decides to time travel and their time travel move is self consistent with the history of U2.
That would be there would be two P2, maybe P2A and P2B and also P1.
So a person would essentially have 2 dimensions,
P(t,u)
are they the same temporal instance from the same universe or are they flat out same person from different universes.
Now let’s imagine a situation where I discover Beethoven music and go back in time and give his own sheet music thus making him recreate his own pieces and later I discover Beethoven.
How does my model solve this lack of origin of information? Easy, the person who went back in time wasn’t actually you, it was you from another universe while when you went back in time to give the music sheet, you went into a different universe to fulfill the other universes history. That means the cause is always in the universe before it, does now it seems there is no origin to this right? No there is.
In U0 for example i discover Beethoven music and decide to go back in time to give to him. Beethoven created his music on his own this when I go back in time, I go back to U1 and thus creating an infinite chain of going back in time into a different universe to give Beethoven the pecie and later discover it.
However on U0 there was no time travel move, Beethoven created his music independently of anything. So always the chain of “bootstraps paradox” is infinite. The cause has an origin. Beethoven discovered on its own which inspired to go back in time to “give it to him” but I give it to another version of Beethoven in another universe.
Any event that could cause a paradox, is immediately not realized and is actually explained by another version of me who did the time travel move, not me.
There is no changing of the past. That event simply did not occur for it to cause a paradox. It occurred in a separate universe where YOU, the traveler, are part of its history and always were.
Of course if you’re history demands you being in it, you’ll be traveling into your own universe. That is if it is compatible history. If it’s not, it was simply not you who did the time traveling in your own universe and if you decide to time travel, you’ll be thrown into a universe where you were always a part of its history.
What if I time travel because I got the idea from me time traveling. Impossible, the desire to time travel should be independent since if I time traveled because I “should” time travel that means how did I know I should the first time, it keeps looping. The desire to time travel because I saw myself time travel means that the person I actually saw wasn’t me and was just me from another universe where they decided to time travel and my universe needed them to complete its history. That means there is a universe where I decided to time travel independently, which led me to a different universe because it’s incompatible with my universe thus creating an endless chain of getting inspired to time travel because I saw “myself” when it was just me from a different universe.
Two people from different universes could time travel in the same universe if that universe has them part of its history.
Let’s say P1 does an incompatible move in U1 and P2 does an incompatible move in U2.
They could both land in U3 and actually meet each other if the history of U3 has them both meeting.
That means that the Time Machine could only control the variable T, if I go to 2030 I got to 2030 no matter what, if I go back to 1899 I go to 1899 no matter what, the variable U however can’t be controlled. I don’t choose which universe I land in.
The laws of reality forbid me from going or traveling back or forward in time in the same universe or another universe if it isn’t part of its consistent history.
What if there was a more advanced model that could control this U variable though?
Like I put coordinates of T:2026 and U:1 for example and it needs to take me there and the machine can’t reject any requests. What would happen? Next post I guess I’ll expand on it since I came up for a solution for this technological advancement.

all these radioactive materials wasnt meant for humans but space craft
radiation the most deadly killer that is silent you dont feel touch it. it touch you. from back in the day radium girls who thought that glowing subtance was upcoming disco to those mexicans finding same kinda color in some script yard all sign their death warrant even some mess with demon core show you close get criticality. all make me think . we use nuclear energy cause is cleaning then our or dirty way getting energy and yet more deadlier . these subtances they call going thru half life give off so much energy it goes right thru you and your cells /maybe we wasnt suppose to have this power . we cant even touch it got have on gear. maybe it another purpose for those who was here before us. space craft can use this energy . think doc on back to the future . according to that movie only way open up time travel portal is with nuclear power. even star trek agrees with this. so im thinking all this radiation is killing us cus we dont suppose to have its for the aliens and their space craft and unless you got a time machine you should not be no where near this stuff

Fainting after reaching your destination?
I'm currently writing a novel about a woman who time-traveled to the past. In one of the chapters, she fainted after reaching another era. I wonder what kind of explanation I would give for that or what kind of medical condition would make that possible. This is pure science fiction btw.

How a Time Loop is explained in Grandfather Paradox series on NJ Pine Barrens folklore
The time loop in the book functions like the old practice of coppicing a branch.
When foresters coppice a branch, they cut it back to a fixed point near the base. The tree doesn't die, it is forced to grow again from that same cut.
Each new growth is shaped by the conditions that follow the cutting.
In Grandfather Paradox, the meteor strike on the blue hole creates a wound in time. That moment becomes the permanent "cut point." When the rift activates, Dallas is thrown back to the exact day the meteor hit. The timeline is cut back to that single fixed moment, just like a branch being cut back to the stump.
From that point, the timeline begins growing again. Because the mushrooms enhance his brain's ability to retain memory across the reset through neural plasticity and enhanced electrical potential, Dallas remembers what happened in the previous growth. Every choice he makes.. every step, every action causes the new timeline to grow differently from the one before it.
The rift can keep doing this for up to seven years.
After that, the unique chemical conditions that hold the wound open begins to lose its potential...
It gets a lot more deeper then that but I'll stop there!

Why I think time travel into the past isnt possible, or made to atleast to the present past of the future. (and how the general public will IF it came to be possible, will never know bout it)
First and foremost, the science, obviously. So setting that aside, which almost everyone in this subreddit do otherwise it wouldnt be a topic of discussion (to the past one)
What reason might you have to travel to the past?
I can only think of two mainly: To make some changes, or to observe the past to gain knowledge.
>Let's talk about the first.
If I had to go back to the past to make some change, that means that thing in the past that wasnt as i wanted it to be, was the cause which made me go back and change it, in the future. Now if i go back and change it, then the cause wont exist, and if the cause wont exist, then i'd never have the need to go back to the past, thus creating a paradox. And since paradoxes are all simply in theories, and can never practically occur in real life, we can definetly say that there wont be any time travelling into the past to change it.
One funny thing i think and like is, that say in case even if we did go back to the past to change it, it will have no effect for our future, that's what i think, is the only possible way changing the past can happen. What i mean is that, the change we make in the past, that exact point in time OR when the travel to past happens, will create another branch of timeline, a different timeline in which that change happened, but it will have no effect for the people of the timeline, which actually made that change. So it could be that many changes were made in the past time, and it kept creating new branches of the timeline, and the one we are living in turned out to be the result of those changes we will never know happened. It's funny to think bout but a possible theory.
This is the only possible solution of the paradox problems like the grandfather paradox.
Thus it is possible that people will realize that changing the past wont do anything for their timeline so why even go through the trouble to actually change it.
(optional read) I came up with this by observing the whole Doraemon plot. You see how in doraemon, satoshi wasnt satisfied with his present, cause nobita fucked up in his life, so he sends back doraemon to help him pull his shit together and actually do something better in life. Now that resulted in actually him marrying shizuka instead of jeko. But if he married shiuk, then satoshi would have never been born, that means he would have never sent back doraemon in the past to change all that, but since it does happen and he does change it, it can only mean that his action created another timeline, all while maintaining the original timeline
>Now the second reason
This is more of a reason which shouldn't create a paradox. Like you just went into the past as a side character, npc, viewed the whole story, took notes came back. Basically you didnt change anything, you didnt interfere with the timeline, you just went their for knowledge.
Now here is the thing, the only ones who might do this would be historians. Like think if u could today go back to the past and unravel the mystery bout how pyramids were made, or any other thing which we barely know bout today. Then you will do it.
The thing is, why would future historians come to our present? If you think about it, almost all of the knowledge or history of the modern era has been recorded very well and preserved through internet, and will surely continue to be the same. Like, everything major which happens in the modern era gets recorded and preserved well enough that u dont need time travel to know bout it. We have video footages, recordings, and simple records other than that too. The only time one will actually travel back to is the pre-modern era, or the time before science and all where this wasnt even a topic of discussion. Like the early 10th century europe, or jurrasic period, or the stone age.
Now if someone does go back there, surely we in the present would have no way of knowing bout it. And no one time travelling would be dumb enough to say they came from the future in Europe a few centuries ago where you would be put on public execution just for saying earth isnt flat and shi like that.
The only time travels that would be made would mostly for general public use, like gaining knowledge of the past, and if any personal use is made, like say going back to know where the treasure is burried, then again it wont be something going public, cause that wont be ur purpose of the time travel.
If you question> then why did no one come up to stephen hawking's party, that doesnt make any major change to conflict with the future and isnt an academic event. Or why no one from the future comes back just to tell they are from the future and predict future things correctly 100 percent of the time or something like that.
WEll you'd know in the next topic:
>Now the reason why IF time travel even becomes a possibility or even if it has, we the general public will never know
I think this should be pretty obvious. Like only very very few selected people and the very few in few governments will know bout it, cuz 1. That shit wont be cheap, obviously. 2. why would u let little johnny know he can go back to the past and tell himself the test answers.
It's like this, time travel is something which has impact on reality itself, if it happens, it isnt something to be meddled with by the common man like you and me, you can barely trust the people with guns, who what they'd do with time travel. And the technology isnt the type you can mass produce, so it would be like something almost all the population wont get access to even if they know it exists. The impact it will make, wont be noticed by the people. This is important cause the only things we know bout which have enormous effect in the world, we know because it cant be hidden if used, like nuclear bombs. U cant practically keep it a secret after using it. But time travel, u can. So, tell me why would any government even make it public. Secondly, it is the sort of info which the government of the country where it is made will seize it, unless it was a collective project. like it will automatically give them an advantage unlike any other thing, so they wont be sharing it, and not even letting the info bout it slip.
This leaves us with the fact that even if time travel came to be a possibility, no one will ever know bout it unless it was an individual or independent project which something like that definetly wont be.
This is also the reason that why if time travel into the past is a possibility, no one went back to stephen hawking's party, because it is something that the ones who have it dont want others to know bout. And since it is something that would never be in the hands or knowledge of the common people or the ones that'd go back in the past, it will never happen.
>But then again at the end time travelling into the past isnt possible cuz of scinece and physics as we know it obviously so all this is just hypothetical bs like every other similar discussion.
let me know what you guys thinkg bout all this.

Time travel.
What year would you go back to if you went to bed and woke up in the designated year? For me, 1976.

Do you believe in the existence of time portals or stargates? If so, does anyone have any books or sources to learn about this? Which countries have Stargates ?
