Thanks for the reply You're right that parts of my theory sound similar to the Many-Worlds Interpretation and Kip Thorne’s wormhole ideas. But what I’m proposing is a bit different. I’m not saying new universes are created by decisions or quantum observations. In my theory, all possible universes are already pre-existing — including ones identical to ours — and time travel happens by entering another universe’s present, which might look like your past or future. So it’s not about branching timelines, it’s about navigating existing ones. Also, the moment a traveler arrives, that universe's future shifts from that point forward which avoids paradoxes without needing to rewrite the traveler’s own timeline. And yes, I based the wormhole limits (like not traveling before creation) on Kip Thorne’s general relativity model. I just want to add I actually came up with this theory originally, without knowing about Everett’s or Thorne’s work when I first thought of it. Later, I started reading more and found out that some parts line up with existing ideas. When you talked about it I just did some research and found out afew things are similar But I didn’t build it off their theories I came to it on my own through logic, and then learned it shares some overlap. I hope it clears things up and people won't think I copied it. Again thanks for the reply

Good question! Let me explain it simply.In my theory, if someone from another universe time travels into this one and tries to create a paradox like stopping me from posting this it wouldn’t "break" the universe or erase anything. Instead, the moment they arrive, this universe’s future would just shift based on their actions.So the future isn’t fixed forever it just follows one path until something changes it, for example like someone new entering our universe from a diff timeline.Also, the person who time-traveled isn’t from this timeline, so they aren’t creating a paradox for themselves. They’re just influencing a new universe that looks like their own, but now takes a different direction from the moment they show up.That’s how the theory avoids paradoxes while still allowing change. Hope that clears it up

I just did a little more research and This doesn't go against Einstein’s theory. In fact, it's based on General Relativity. According to physicist Kip Thorne (who used Einstein's equations), time travel through a wormhole can’t take you to a time before the wormhole was created. That’s not a flaw — it's a known rule in real physics ics. If the universe is truly infinite and allows variation, then every possible arrangement of particles including the exact arrangement that forms you, your life, and our universe should eventually repeat. So even if the chance of another exact version of you is incredibly small, in an infinite universe, small probabilities still happen an infinite number of times. That’s why infinite versions of ourselves will exist if universe in infinite it can be one in one septillion doesn't matter still infinite version of everything of our universe will exist

KJW Thanks for the reply that Burnside problem is a cool angle I hadn’t heard of before. I get your point that just because something is infinite doesn’t guarantee that every pattern (like an exact replica of our universe) must appear. That’s definitely true in pure math. But my theory is based more on physics than abstract math. In an infinite universe made of finite particles and combinations, the chances of exact patterns repeating even really rare ones becomes extremely high. That’s the logic behind assuming there could be a universe that’s 100% the same as ours up to a point. From what I’ve read, physicists like Max Tegmark support this idea too that infinite space basically guarantees near or exact duplicates just based on probability and limited combinations. So I totally see where you’re coming from, but I still think (in a physics context) it’s more likely that exact versions of us exist somewhere. So it's not guaranteed but in this case the most likely one is if universe is infinite then there should be infinite version of ourselves Thanks again I really appreciate your reply

Multiversal Time Travel Theory By me(Atul) Basic Concept for the theory For the theory to work we first have to believe that universe is infinite If the universe is infinite, then there must be infinite versions of our universe. This means:There are infinite copies of Earth, of us, of this moment everything There will be infinite universes 100% identical to ours completely because everything matching perfectly it can be one in septillion and even more That includes universes where everything matches perfectly same people, same atoms, same history just like ours. Now the theory is if we time travel we won't travel in time in our universe instead we will travel in time a 100% replica of our universe a same version of our universe. Now it fixes everything Time Travel Without Paradox This theory solves the grandfather paradox. Usually, the paradox says: If you go back in time and kill your grandfather, you wouldn’t be born, so you couldn’t go back to kill him creating a contradiction.But in my theory, when you time travel: You don’t travel within your own universe.You enter a different version of the universe that is exactly the same up to that point in time. now here's the thing as I said future Is already decided so like when you travel in time the replica you entered can be still in past because but since future is already decided it has the same future as the where you traveled from you can only time travel to those with everything same and the also the decided future is same so if you even go to future there it's the same future as the original one since future is already decided. Now get back to the paradox So if you kill your grandfather in that world, only the version of you from that world will never be born. But you came from another universe, so you still exist That means no paradox. Timeline Shifts Once you enter another universe: The future of that universe starts changing because of you because as soon as you enter that universe the determined future will get changed The universe you left also the future from that universe changes because you’re no longer there.( This theory supports future being already decided) From the moment you arrive, the two universes are no longer identical. That’s why two versions of you can exist: One that belongs to the new universe (maybe still a child or unborn) One that came from another world (you)(me) Wormholes Are the Key Time travel happens through wormholes, which are like tunnels between space and time. The idea is: One side of the wormhole is a black hole (entry point) The other side is a white hole (exit point — still hypothetical, but supported by Einstein’s equations) The wormhole doesn’t just go through time — it also connects to a different universe. That universe is The closest possible match to ours At the exact time we want to travel to Limits of Time Travel There are two major limits: 1. We can’t go back further than the moment the wormhole was created. Example: If the wormhole was made in 1950, we can’t travel to 1800. 2. We can’t go forward beyond the time the wormhole still exists. If the wormhole collapses in 2070, we can’t travel to 2080. So our travel range is only between the wormhole’s birth and death. How the Wormhole Connects Wormholes link to the nearest matching universe the one with the same atoms, people, and history.because if everything is same then there will be the wormhole in that universe we are using and both same wormholes will get connected It’s not random, but it's not controllable (yet). Maybe in the future, scientists can control which universe to connect to but in this theory, it just connects to the closest match by default. About White Holes White holes are the opposite of black holes instead of sucking matter in, they push it out. They are not yet found, but the math from Einstein’s theories suggests they exist, just like black holes were only theoretical before being confirmed. This theory accepts white holes as real to allow the wormhole to work properly. Math Not Included Yet because I am pretty young so I still haven't reached that level of math to show it. I just gave this theory based on the knowledge I got from videos and articles and created a theory. I don't know how much of the theory make sense and logical that's why I posted it here So now Time travel works by moving into another version of the universe, not by changing your own. No paradox happens because the version of you in that universe isn’t affected. Wormholes act as bridges between universes and points in time. As soon as you enter the universe future will change so you can't go to the original one you can only go to the changed future like universe and instead of just wormhole the whole universe has to be same to same in order to travel And this theory suggests you're not going to future or past you're going to a universe which timeline is either ahead or behind the timeline of our universe so because of that it doesn't effect the flow of time. Like our universe is in 2025 but you can go to a another universe which haven't reached out timeline but since future is decided you will reach a universe which can be in 1900 but has the same future in 2025 of that universe will be completely same to our 2025 universe. like you can reach a universe which is ahead of us and is in 2300 but since future is decided our 2300 will be same to same to their 2300 and yes you don't know what timeline you're going. And after you go to one since future changes of that universe you're no longer connected to the one you came so you have to somehow travel through space to find your universe
