If going back in time is possible, then that means the past still exists. If the past still exists, then that means we are functionally immortal. We exist within our frame of reference ( our lifetime) and we always will.
As a kid I wanted to go back in time to see a dinosaur. Now I wanted to go back in 2020 to appreciate, and save someone. I would do anything to bring him back. I just wanted to see him even one last time.
Everyday I travel back and forth in time. Its simple and we all do it. Its called "MIND TRAVEL" and it is also faster than light. You all need to try it someday. Our mind is the most powerful thing on earth.
@@jimmyjohns2201 god or a higher “being” will not be bound by time and space. He would be a “Being” that’s everywhere and anywhere at all times. So if you really mean GOD GOD he for sure would be able to go rewind time or fasffoward. Especially if he’s able to bring back ppl from the dead. That’s literally undoing something that been done. I call that reversing time. Same concept.
I actually went back in time, to 1976. I met myself...and I said to myself that I was myself, from the future. When I told myself that I was from the future, myself said, that I was myself. So, yeah, I had a great time with me, myself and I.

@@manoo422 For us to use this, we'd have to somehow be able to detach ourself from time entirely. If this became possible in some way, I still don't think we'd be able to use it directly since humans are made to work with linear time. We'd have to make a mini-universe with its own time, then put ourselves in it, detach that mini universe from this universe. Then somehow be able to turn a knob of some sort to increase or decrease the speed of time in our detached universe relative to this universe, and lastly attach our mini-universe to this one again at the specific time we want. Oh and also we'd somehow need to see/know how all this behaves first so that we know we have the right settings and reatachement. Sounds fun!

Neil is one of my favorite people in the world! I think that if everyone would listen to him, instead of what's "self-destructive" in the world, we would have a chance at world harmony. He brings harmony into the world with his knowledge and character.
But the black & white aspect of it is a short-cut, therefore involving a bit of "cheating"! I.e. the past is/was not "quaint" or nostalgic &--except for a few treasured--moments--it is as mundane as the present. But when one "relives" it it emanates something rare and exotic.

it’s super sad and corny that i even searched this up, but rn i’m at a moment in my life where tbh i need this. last summer i was the happiest i had ever been, and its been killing me that i took that time for granted. there were people and different aspects of life during that specific summer that made me just extremely happy, but now i feel as if i can’t get that feeling back again. friends tell me “oh yeah it was just your ex” but if anything she’s just an aspect of that. life isn’t the worst right now and i’m happy that i met people on the journey to where i am right now, im just not as happy as i was back then, and i can’t stress how happy i was. i hope someone can relate to this because honestly i haven’t put this much thought into a comment ina while lmao. TL;DR, i searched up how to time travel stupidly because i miss a period of my life from the past.
I always assumed that if you managed to go back in time, you'd probably be in a separate reality, not the original one you were from. Basically a branched reality where things and events transpire differently. That would explain the grandfather paradox.
Well ya gotta remember that what we think of as the past present and future actually ALL coexist simultaneously. We only conceive those notions because of the speed of light. So if you were to “go backwards in time” you wouldn’t be aware of it - you’d literally be reliving the “past” all over again - making the exact same choices, meeting the exact same people etc. This is why you couldn’t go back and change things. This is also why it’s impossible to travel back to a time before you were born.
yeah but that just make it pointless then. cause that just means you are not going back in time, you are just going to a diffrent world which has not advanced in time as your world and screwing with it for no reason.
The 'Many Worlds' theory is complete fantasy made up to try and explain time travel paradoxes which in reality dont exist anyway so the whole idea is redundant dribble.
I think the paradox would be dealt with, IF each movement back in space-time then created a whole new branch of space-time at that point. So, you go back to 1900 and from that point there becomes now two divergent space-time branches. The original branch then remains unchanged because your self is no longer on that branch after whatever point you leave. Each time you move forward or backwards a new branch is created, meaning you keep moving `forward` in a relative sense through each new branch you create, regardless of where it is on the timeline. In that case, you could kill your parents before they had you and avoid a paradox, because `you` weren't born on the space-time branch you killed them on and *that* space-time branch still exists unchanged to the point you left it. There's not a shred of scientific evidence to support that idea though, so it's kind of just mental fluff. What would it take to overcome that paradox?
that is the many worlds theory and yeah it would beat the paradox but at the same time they would still be alive in the other world where in time and space he could not kill his parents and prevent his own birth thus the paradox.
Well if your able to branch off into another reality by going back in time then we would have to be living in a simulation I believe or humans would've created a whole new reality which would make us God's pretty much
@@IceMontgomery I just borrowed the one already being used and you can't fix a paradox if there is none to fix. It's a thought experiment. Grow Up princess.
What about the idea that any attempt to do so wouldn't happen because your time traveling into the past was part of history all along so you aren't capable of altering anything that didn't already happen.
Going to future is possible and we can already do that. In fact there's already someone who did it. But going to the past is not yet possible or there's still no way to confidently say that there's a way to go back
Going back in time would be cool to see all the people I have lost. Meaning the ones that died to early. But I wouldn’t want to stay in that time frame though. Because one I would see my younger self and there is no room for two of me. Also all the people that love me and ones I love are in this time line. If I can see the ones I lost one more time just to give them a hug…. That would be wonderful and thinking about that right now has me in tears.
There is a thing that is possible in theory, it’s to observe the past. With a theoretical warp drive the theoretical upper limit of speed is ridiculously high. If you have a huge planet size telescope (gravitational lens) you have the chance to look back in time. Just as we see only the past through our lenses, if we leave Earth with extreme speed and look back on it with high enough mqgnification we could see our past. With the speed and distance you can calculate how far you want to look back. So theoretically we could have a look on dinosaurs or whatever. Fun thing to think about it.
@@tmxband You can't see the dinosaurs unless you're already at the required distance or, you travel faster than light. Leaving Earth at light speed and then turning around to look at Earth will only give you light from the day you left.
@@deenell9039you still wouldn’t be able to see the dinosaurs. There’s no way to see back in time in that aspect. In theory if you traveled an arbitrary number of light years away from earth and looked back through a telescope you’d still be seeing earth the day you left because you’re just magnifying the image to be visible. You aren’t seeing images like an iPhone sends, you’re seeing a physical surface, light particles don’t carry the image. There’s no way to travel back to past events. Back in “time” in theory, yes. But not to past events.
A hypothesis: time does go backwards but that started with antiparticles at the "big bang" and they are going backwards in time from there, we only can see the forward traveling particles. We can see the backwards type particles very rarely but most are at the other end of time.
Lets get one thing straight. If you could travel faster than light you would indeed be traveling backward in time. However it is IMPOSSIBLE to also remain in the same place. In other words you would not be able to travel through time alone. Which means you will always travel a DISTANCE in order to go backward. If you tried to return to your starting position you would in fact have to travel through the Bulk( If it is a thing anyway). The only way that this works is if you travel to a distant point faster than light,( So you travel back in time) then you would have to turn around and travel back to you starting point at sub-light speeds taking the length of time equal to the distance traveled. The wormhole is only possible for that brief period that you travel at FTL speeds. You would end up at your destination near instantly. At least this is the way I think about it. It could also be the case that the only way to travel through time is to use an engine that would instantly launch you through a wormhole to the same point in space but backward in time, however this would require all the energy of the universe, I suppose it might be possible to only create a local distortion but I doubt it. Locally it would create a new separate timeline, if in fact you could build up enough energy sitting still (relatively speaking) to instantly launch into the past. It would have to be a instant transition otherwise you would end up as paste on the bulkhead. I still think my first thought is more accurate though
i mean the distance travelled doesnt need to be in a straight line tho does it like travelling in a circular motion from a distance qhere we can at least observe our planet from?
It still wouldn’t allow you to go to a period of “time” of past events. “Time” is just a certain amount of units we measure daylight in dictated by the earths orbit around sun. Other planets have different “time” speeds. It’s truly a misconception when people say you can time travel. If you traveled 5 light years away and then traveled back to your starting point at regular speed, you’d be the exact same age the day you returned. A 40 year old man is still a 40 year old man whether he’s traveling super fast or not and he is still dead after 5 light years the same as the person on earth would be dead. Deterioration and aging is still a thing even if “time” travel is possible. Which it isn’t in the idea going to different places in history.
@@mountaineerdefense2507couldn't agree more, the only way to potentially 'time travel' would be in a cryptosleep casket. Where you would be perfectly preserved the way you are while the world changes around you. No matter how fast you travel somewhere the only thing that would change is how quickly you arrive at your destination.
In my opinion, speed does not affect time. Traveling quickly through space does not equate to preserving time relative to another person; it simply means covering more distance in less time. Time is the same everywhere in the universe. It all ages at the same exact rate. Traveling at the speed of light would not cause you travel backwards or forwards in time; you're just moving through space rapidly. Where you end up will be the same time no matter where you are. If I were able to travel to the nearest galaxy instantly, there would be no time dilation. I would reach my destination at precisely the same time I departed from Earth, plus or minus a few fractions of a second, since even an instantaneous journey would involve a small measure of time. Though, if I came back to Earth a few seconds later, nothing would have changed on Earth except for the few seconds that passed during my trip. Regarding light, it's true that we are, in a way, looking into the past when observing distant objects like galaxies and stars. This phenomenon occurs because of the time it takes for light particles to travel across vast distances before becoming visible to us. The time it takes for light to travel to us differs significantly from the actual time at its source. The light we observe may have traveled for millions or billions of years before reaching us, allowing us to see the universe as it was when that light began its journey. However, this does not imply that we can physically travel back in time. If a beam of light from a distant star reached Earth at this moment and you could instantly teleport to that star's origin, you would see the star as it currently exists, rather than the light we observe from Earth. The star you traveled to may not even exist anymore. Watching it feels akin to viewing an old black and white film. It's like reviewing a tangible record of events that occurred in the past but have since ended or changed significantly over time. Also, consider how we use phones to communicate. If I'm in Texas and make a call to someone in France, we're speaking and seeing each other in real time for the most part. Though the speed at which our data moves may cause a slight time delay, we still exist in the same time. If I were in Texas and my friend was on Mars, there would be a time delay from data having to travel that far, though we still exist in the same time. I'd essentially be seeing a recording of my friend rather than seeing him in real time, but that doesn't mean either one of us has moved into the future and/or the past. Time is constant and moves in one direction at one pace, forward and steady.
I have a very basic question that I have wondered for a very long time. If I travel at the speed of light from earth. This would mean everyone on earth is also travelling at the speed of light relative to me. So how can my clock tick slower (or not tick at all) while Earth's clock tick normal. I mean why would time stop/slow down for me and not for Earth? Why and how would I travel in future in that case? I mean who is to say who is travelling at the speed of light? Since it is all relative?
I like Doc browns explanation (basis in fact or not) of sending Einstein (the dog, not the physicist) one minute into the future, so that he skips over that minute, and reappears when Marty and Doc's (perception of) time catches up.
It's a movie so I went with it, but in reality I would think Einstein would always be one minute ahead of them in time. They can't catch up to him because he is one minute ahead of them.
Traveling at the speed of light is the most difficult part. Everything will seem stretched out and that'll make if almost impossible to physically locate where you wanna go in time. Unless the machine is preset to that particular place and time.
What type of materials on earth or from other planet or galaxy can we use, at certain speed not even closer to lights speed the item gets overheated then burn and explode
Time dilation is something to avoid with FTL travel, I mean you want to get home when all your loved ones are still alive or the entire human race for that matter. So, faster than light without time travel.
Well ya gotta remember that what we think of as the past present and future actually ALL coexist simultaneously. We only conceive those notions because of the speed of light. So if you were to “go backwards in time” you wouldn’t be aware of it - you’d literally be reliving the “past” all over again - making the exact same choices, meeting the exact same people etc. This is why you couldn’t go back and change things. This is also why you can’t go back to a time before you were born.
My question is why go back in time if it would be different from the actual past. I would want to go back to see people I loved and events I remember. If that’s not what it’s going to be then it’s nothing more than a trip to the unknown.
Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city complain about the same time paradox unless it was effected by it. Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're randomly given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? Ti-i-i-ime, is on my side. Yes, it is!
Maybe it's the weather? Maybe a local sporting event? Maybe a local news story? Depending on these events, being positive or negative could shape peoples perception of the day, not some time distortion.
Time goes by very fast when you actually are engaging in certain activities. My job is very fast paced and I have a lot of things to do within a short period of time. Being busy and NOT being busy, aka clock watching are 2 different things. You never hear of people complaining their sleeping time went too slow when they sleep 8 to 9 hours.
@@mikewolverton7904 If you can think of a better way to do a blind survey - of an entire city - in that small window of opportunity, well then, I'm all in. Until then, I invite you to spend a couple years in the subways. Between 2pm -10pm and you'll see for yourself. Just listen as an entire city gets off of work and gets out of school. You'll see it's more than a, "coincidence of circumstances." ;-P
Time flies when you're having fun. How true! However, this has nothing to do with time. It's a purely chemical reaction in the brain. All perception. Good example.....when you're running late trying to get to work on time. Every red light on the way lasts longer than normal.....It doesn't really. Every other driver on the road is driving way too slow........they're not!! It's just your impatient brain. Next time, leave the house earlier!!!
It's too difficult to imagine to time travel to the past. How do we travel back in time physically? How do we set specific day/time? Where on Earth will you locate? etc... First we must figure out how to travel to the past, then a million more questions to answer.
Time traveling backwards is impossible. The Earth, Sun, all of the planets, the galaxy are all moving objects. They are not stationary. There is no rewind button. It's not just a matter of traveling through time, but also moving objects back into place. It just can't be done.
In other words, we can go forward in time from the present and the future would become our present, then we can travel back to when we left, making it our "past" but only at the time which was once the present we left.
its the latter. Like if you took a boat trip that took days, versus a plane that took a few hours. You arrived alot sooner by plane, meaning you aged less. The theory is correct but the conclusion that its in effect time travel, is nonsense. Two people racing on a track, have the same time ticking, one just arrives at their destination sooner. Far as im concerned, you cannot travel and end up at the spot yo started, just because you moved fast
I believe there is a theory that, with a block universe (past present and future all exist), you or something going back in time would have already done that, thereby solving the “grandfather paradox”. In effect, the universe and causality may be “protected” up until the point that a Time Machine is invented or, say, a black hole “time Machine” is used. But that just how I unrest and it. Isn’t the dunning Krueger effect awesome? Lol.
Its so fascinating to listen about time travel, thanks for such content. If there is indeed space time to be invented in future, it could be done outside Suns Gravity field where Voyager are travelling now. If somehow we get something stationary at Sun's Lagrange point and shoot anyone back to earth by heavy detonation to move anything back to earth from there, they could have experienced huge time travelling, if i'm not missing. Till next century humans may get that technology. Hopefully if survive.
I think that it is better to always be going forward.Sometimes we think of the past and have trouble moving on. If you were able to be with people and places from your past you may not want to move forward at all.I think that it would be a mistake to take our brightest minds and have them working to go backwards. Especially when they could be working to advance mankind.
Scariest thing is.... if we do eventually figure out time travel, why dont we have time travellers here now? Either we never figure it out. Or its kept under VERY strict use, in a way that nobody here today knows about it.
There would have to be very strict rules and likely limited use of the tech. Imagine if just anyone could travel back in time...they could mess up so much stuff. Many people would abuse it for personal gain. Also, consider the time-traveler that actually goes to their past. Who would believe them if they tried to convince people that they were from the future? And if they did have tech or knowledge to prove it, then they would likely be captured and forced to help those in that timeframe understand future events/tech. They would likely keep quiet to avoid that...if they ever wanted to return to their point of origin. I believe it's not impossible we've been visited but 99.9%+ of us would never find out because it would be very carefully and secretly done.
We like to dream of going back, but it usually implies being young again and avoiding the mistakes we made. I'm reminded of the old Twilight Zone episode "Of Late I Think of Cliffordville," which turns out rather badly for the time traveler.
I would love to go back in time and correct my mistakes! But if you couldn’t change your mind and make different decisions, then I don’t see the value of taking what seems like a risk.
Only thing that sucks about any possibility of ending up in the body of your former self to redo everything the "right" way is A) trying to work around any unreasonable members of your family in a wholly new way & B) changing the future enough to where you no longer have any precondition of what will happen next.
It is indeed possible to travel backward or forward in time, provided the space craft the passengers that are on board is powered by dilithium crystals to propel the conveyance to the chosen direction of destination. Should the craft experience dire malfunction during transit due to overheating, the auxiliary emergency power unit may always be engaged to carry on with the long arduous journey. 🤔
I have been diagnosed wth Huntington in 2010. I went through a series of unfortunate additionate events (for one, i have food allergic allergies after forgetting to take a medication). Would love to return to 2009 to make things easier)
I wonder if this could be done on a "micro" scale instead of using light years and endless space (not knowing exactly where you will end up) but something much smaller where you could control precisely where you enter and exit the "wormhole" in question required to travel back and forth in time (miniature black hole etc)
A wormhole cannot be left at any point along its length. You enter at the entrance and exit at the exit. However, from what I've heard of the Tipler cylinder (not just this video), you can choose your exit point.
Doc Brown, in Back to The Future, illustrates why travel backwards in time hasnt happened, nor will it. Not only do we all live the same space time continuum, we all live the only space time continuum. Travel backwards in time creates a new continuum that, no matter how minisule in degree change, eventually becomes vast over time - erasing us all. An example would be charting your course across the ocean for a distant lighthouse thousands of miles away. If you start your voyage 600 meters away, a minisule error stills lands you at the lighthouse. However, over thousands of miles this small error lands the Voyager nowhere close to the lighthouse. Indeed, the lighthouse would likely not even be seen. Any interaction with the past, no matter how small or seemingly insignificant, changes the trajectory of time moving forward which, like the misguided seafarer, eventually removes earth from its destination.
In terms of paradoxes i believe the universe is what it is, we as humans give ourselves to much importance, so, to me, if we travel back in time we would just erase our original timeline but it wont destroy the traveller
But, yea, i dont know how the universe will justify that, for now you cannot create energy and matter from nothing because thats how you will be seen in this past universe.
Most folks (even geniuses)(genii?) neglect the first three dimensions when talking Time Travel (TT). Somewhere else in Time is also somewhere else in space. Think anti-aircraft gunnery, you don't aim at the aircraft, you aim at where you expect it to be by the time your shell gets to it. To go back in time (or forward) even a week you'd find yourself gasping out the last of a suddenly abbreviated lifespan, in the cold vacuum of the cosmos ... so unless you can sort that one out you'd be (very quickly) not you but an ex-you.
@@omniking9631 It's impossible to not interact. Once they appear they have interacted. Just taking up space is an interaction. It's not unlike the simpsons episode where Homer travels back in time.

The child was supposed to have died from malaria. They don't die now and end up becoming a great scientist or a horrible tyrant who starts WWIII.

@@barongordo591 A travel back to time automatically creates a new timeline. Timeline intended to be visited before time travel still exists but is basically inaccessible to time traveler.
@@emilyhopemeechem4183 “if” just means speculation. The moment is all that exists so we should live in it. But think about this. If conservation of energy says nothing can be created or destroyed, just converted, then time travel would both create and destroy.
My theory is time travel into the past is possible and even if we changed something that happened in the past there is a way that things could work out without causing any paradoxes. For example, let's take the famous grandfather paradox. Let's assume that someone has traveled back in time and killed his grandfather. In that scenario, his actions won't be affected to his timeline or future. It will only make a branch alternative timeline, which is connected to the main timeline, where his grandfather is dead. In that way they all make sense.
See, that's not really how I interpret the multiverse or multiple worlds theories. I still think you are bound to your universe, allowing all the paradoxes to still affect you as long as you are stuck in your universe.
A branched timeline happens when you went back in time to make some changes Time is not just a straight line but it’s natural If you changed something in the past, then it would not affect the timeline we live in Branched timelines depend on other peoples decisions for if one person grows up to start a family or dies young
If time is traveling in waves like in the water, that means past exist. Not only do the past exist in this scenario, also alternative worlds because new waves will form just like in the ocean. It goes and come back again and again etc.
Time doesnt tick slower. Time never changes. Us going faster and faster is just changing our speed, nothing else. Our observation is affected, but not time. Time is still ticking away the same throughout the cosmos. It doesnt depend on whatever we do. We never "look back through time" We see images of things that happened in the past. Can't touch it, can't change it, we just capture the image when it finally reaches us.
Because it is impossible to travel back in time. Traveli back in time means you set trillion planets and stars in universe backwards which is imposibble
Because it's just impossible to go in past buddy past doesn't exist because those things has happened already, talking about going ahead in time yes there are many possibilities to that .
My understanding of wormholes is that they are so unstable in theory that the mere act of entering it would cause it to collapse making it essentially useless for any kind of travel.

Cant tell me I cant go back in time...I just watched a recording/video you made 3 days ago. Now I'm commenting on it. Light and sound waves can be captured onto film and played over and over again....the past constantly being witnessed in the present. Half the stars in the night sky are dead, but ironically thier light still glows brightly. As for interacting will the past...what di you think I'm doing now or should I say was doing🤣
@@Haildawn Light and sound waves are the key to witnessing ancient history. You cant undo or interact with it, but you can still observe its passing. Like I said, as our stars shine still- they have long since died. An interesting thought is a present day alien planet observing the light from earths past, seeing maybe the Roman Empire and thinking that's how life here is now in our present.
I can confirm that time travel is possible as I am from the year 2250 and through the theories explained here we were able to go back in time. This has proved useful as hopefully in the past we can prevent the current future from occurring as the lizard people have taken over and I was sent in the past to prevent them from taking control.
When you consider looking into this universe to go anywhere, is to travel back in time, and whatever your target is will no longer be there, so how does that work?
The grandfather paradox is simple, if you went back and stopped your parents from meeting eachother it would change that timeline but not the one you lived, so you would still exist in your own timeline!
I feel like that is essentially the concept of being "in the eye of the storm." You are at the center of events but removed from the repercussions of time travel intervention.
If you could travel back in time. Would you experience an unending sense of Deja Vu? Since you would be putting yourself back in a point in time that you have already lived.
I think it depends on whether someone's age decreases to match the age they were in the past. Or are they relatively the same age they were when they began travelling to the past? In other words, are they able to observe a younger version of themselves?
You would run into your past self so you would have to kill your old self, and replace them. Then brings in the time paradox question, does killing yourself after traveling to the past change the fact that you already traveled to the past?
@@papasmurf205 no that's BS nothing will happen where do people get that theory from. but if you do end up killing yourself from the past then you from the past will not exist you will prevent yourself in the future in that timeline
Every time you sleep, your mind leaves the present, then travels in the future but your body advances through the normal flow of time. At wake moment, your body catches up with your mind. Time travel is not yet a scientific reality but it is a spiritual one. 🤭
if going forward in time you need to go to speed of ligth, you need a positive speed, is there anything about negative speed? if there is a negative to every positive, should a negative speed of ligth can make you go back in time? and, will it be posible for a negative speed?
If there was something that forced you to land outside your past light cone when you travel to the past, then the Grandfather Paradox is solved, too. Isn't it?
I think ive heard the outer solar system probes have used slingshot maneuver to gain speed. Was its chronometer affected? Or just not fast enough? What if a sun slingshot of multiple passes, would it slow the chronometer down?
I would love to go back to the 1960s, but the way I was...a Kid. To really appreciate and love my parents even more than I did. Maybe attend college this time, and hang out with a bunch of other fellows 😉⏲
slowing your rate of aging or making your clock tick slower isn't traveling into the future. do you think the items in your freezer are traveling into the future? do you think you're traveling into the future when you go to sleep at night? As I see it, time is just the product of us keeping track of changes. it's not some dimension that we can travel through or anything can extend into. everything is very much stuck in the present. your claim of being able to travel into the future is limited to moving a few nanoseconds, a negligible about of time that is very easily inside any marine of error, if you travel at or faster than the speed of light, which is a very impossible feet.
So if I am 20 years old and travel away from earth at a speed of light, come back in one year to see all my friends of same age are now 80 years old instead of 21 because of time dialation. Would you consider that time travel?
@@ScottJPowers I would disagree with you; If in one year relative to earth time I manage to move forward 80 years, I would consider it a time travel. But I guess you may be thinking about moving forward in time without traveling at a speed of light. I hope one day we might be able to it.
Your freezer analogy is not relevant. As you approach the speed of light, you don't start to age more slowly or experience time slowly (in your own point of reference). It is compared to others that you have aged more slowly and clocks have ticked more slowly. To me, that is time travel. Admittedly, it is nothing like Dr Who or Back to the Future.
You want to be careful going through wormholes. John Crichton went through one and his life was turned upside down. Two species that were warring with each other both chased him everywhere to get his wormhole knowledge. On the positive side of things, he hooked up with a really hot alien girl that sounded very similar to an Australian.
oh so thats why i'm in the future of my gps navigation.. it always tells me to turn left or right some time after i should have done it.. amazing and sometimes i will text my mom before she ask me something
But is that not relative to a certain time? Perhaps a downscale time relevant for our own comprehension? Perhaps the faster you go the closer u only get to the thread time??? Just thinking though

That’s the only way. Also moments captured on camera, stills or videos and clothes from the past.

If going back in time is possible, then that means the past still exists. If the past still exists, then that means we are functionally immortal. We exist within our frame of reference ( our lifetime) and we always will.

Time Travel I Wanted To Go Back In 1989!
Oh great year!
Time isn’t linear, humans just perceive it like that because we are born, live and die creating a past, present and future but time and space are one it exists all at once.
This is a possibility I've been thinking alot about too.
Hence the ability to travel back and forth to any point.
@@manoo422 For us to use this, we'd have to somehow be able to detach ourself from time entirely. If this became possible in some way, I still don't think we'd be able to use it directly since humans are made to work with linear time. We'd have to make a mini-universe with its own time, then put ourselves in it, detach that mini universe from this universe. Then somehow be able to turn a knob of some sort to increase or decrease the speed of time in our detached universe relative to this universe, and lastly attach our mini-universe to this one again at the specific time we want. Oh and also we'd somehow need to see/know how all this behaves first so that we know we have the right settings and reatachement. Sounds fun!

When I want to go back in time, I watch old black & white 1930's movies.
They're a way to look into the past, way before I was born.
I never thought of it like that so there already is a time machine deep thought!
But the black & white aspect of it is a short-cut, therefore involving a bit of "cheating"! I.e. the past is/was not "quaint" or nostalgic &--except for a few treasured--moments--it is as mundane as the present. But when one "relives" it it emanates something rare and exotic.
I want this to go back in the past when i was wrong and i could save everyone my friends and love ones and be grown myself too much hoping thats too perfect
it’s super sad and corny that i even searched this up, but rn i’m at a moment in my life where tbh i need this. last summer i was the happiest i had ever been, and its been killing me that i took that time for granted. there were people and different aspects of life during that specific summer that made me just extremely happy, but now i feel as if i can’t get that feeling back again. friends tell me “oh yeah it was just your ex” but if anything she’s just an aspect of that. life isn’t the worst right now and i’m happy that i met people on the journey to where i am right now, im just not as happy as i was back then, and i can’t stress how happy i was. i hope someone can relate to this because honestly i haven’t put this much thought into a comment ina while lmao. TL;DR, i searched up how to time travel stupidly because i miss a period of my life from the past.
I ain’t reading allat
I can relate, I have the same feeling right now…
I always assumed that if you managed to go back in time, you'd probably be in a separate reality, not the original one you were from. Basically a branched reality where things and events transpire differently. That would explain the grandfather paradox.
I totaly agree with that ... nobody is gone change what happend ... you just build a separate time path
Well ya gotta remember that what we think of as the past present and future actually ALL coexist simultaneously. We only conceive those notions because of the speed of light. So if you were to “go backwards in time” you wouldn’t be aware of it - you’d literally be reliving the “past” all over again - making the exact same choices, meeting the exact same people etc. This is why you couldn’t go back and change things.
This is also why it’s impossible to travel back to a time before you were born.
yeah but that just make it pointless then. cause that just means you are not going back in time, you are just going to a diffrent world which has not advanced in time as your world and screwing with it for no reason.
Always assuming? Thank you for not understanding science.
The 'Many Worlds' theory is complete fantasy made up to try and explain time travel paradoxes which in reality dont exist anyway so the whole idea is redundant dribble.
I think the paradox would be dealt with, IF each movement back in space-time then created a whole new branch of space-time at that point. So, you go back to 1900 and from that point there becomes now two divergent space-time branches. The original branch then remains unchanged because your self is no longer on that branch after whatever point you leave. Each time you move forward or backwards a new branch is created, meaning you keep moving `forward` in a relative sense through each new branch you create, regardless of where it is on the timeline. In that case, you could kill your parents before they had you and avoid a paradox, because `you` weren't born on the space-time branch you killed them on and *that* space-time branch still exists unchanged to the point you left it. There's not a shred of scientific evidence to support that idea though, so it's kind of just mental fluff. What would it take to overcome that paradox?
that is the many worlds theory and yeah it would beat the paradox but at the same time they would still be alive in the other world where in time and space he could not kill his parents and prevent his own birth thus the paradox.
Well if your able to branch off into another reality by going back in time then we would have to be living in a simulation I believe or humans would've created a whole new reality which would make us God's pretty much
Killing your parents in any scenario is such a poor example to use. My God get some help.
@@IceMontgomery I just borrowed the one already being used and you can't fix a paradox if there is none to fix. It's a thought experiment. Grow Up princess.
What about the idea that any attempt to do so wouldn't happen because your time traveling into the past was part of history all along so you aren't capable of altering anything that didn't already happen.
Awesome. I understood nothing from this video.
😂😂😂😂
You’ll get there. In time…
Going to future is possible and we can already do that. In fact there's already someone who did it.
But going to the past is not yet possible or there's still no way to confidently say that there's a way to go back
😂😂😂
Then why did you watch it lol
Going back in time would be cool to see all the people I have lost. Meaning the ones that died to early. But I wouldn’t want to stay in that time frame though. Because one I would see my younger self and there is no room for two of me. Also all the people that love me and ones I love are in this time line.
If I can see the ones I lost one more time just to give them a hug…. That would be wonderful and thinking about that right now has me in tears.
A new thing I just thought of: what if it's only possible to view the past, but the second you stop moving, your real time catches back up with you?
There is a thing that is possible in theory, it’s to observe the past. With a theoretical warp drive the theoretical upper limit of speed is ridiculously high. If you have a huge planet size telescope (gravitational lens) you have the chance to look back in time. Just as we see only the past through our lenses, if we leave Earth with extreme speed and look back on it with high enough mqgnification we could see our past. With the speed and distance you can calculate how far you want to look back. So theoretically we could have a look on dinosaurs or whatever. Fun thing to think about it.
This is my theory too
@@tmxband You can't see the dinosaurs unless you're already at the required distance or, you travel faster than light. Leaving Earth at light speed and then turning around to look at Earth will only give you light from the day you left.
@@deenell9039you still wouldn’t be able to see the dinosaurs. There’s no way to see back in time in that aspect. In theory if you traveled an arbitrary number of light years away from earth and looked back through a telescope you’d still be seeing earth the day you left because you’re just magnifying the image to be visible. You aren’t seeing images like an iPhone sends, you’re seeing a physical surface, light particles don’t carry the image. There’s no way to travel back to past events. Back in “time” in theory, yes. But not to past events.
A hypothesis: time does go backwards but that started with antiparticles at the "big bang" and they are going backwards in time from there, we only can see the forward traveling particles. We can see the backwards type particles very rarely but most are at the other end of time.
Lets get one thing straight. If you could travel faster than light you would indeed be traveling backward in time. However it is IMPOSSIBLE to also remain in the same place. In other words you would not be able to travel through time alone. Which means you will always travel a DISTANCE in order to go backward. If you tried to return to your starting position you would in fact have to travel through the Bulk( If it is a thing anyway). The only way that this works is if you travel to a distant point faster than light,( So you travel back in time) then you would have to turn around and travel back to you starting point at sub-light speeds taking the length of time equal to the distance traveled. The wormhole is only possible for that brief period that you travel at FTL speeds. You would end up at your destination near instantly. At least this is the way I think about it. It could also be the case that the only way to travel through time is to use an engine that would instantly launch you through a wormhole to the same point in space but backward in time, however this would require all the energy of the universe, I suppose it might be possible to only create a local distortion but I doubt it. Locally it would create a new separate timeline, if in fact you could build up enough energy sitting still (relatively speaking) to instantly launch into the past. It would have to be a instant transition otherwise you would end up as paste on the bulkhead. I still think my first thought is more accurate though
i mean the distance travelled doesnt need to be in a straight line tho does it like travelling in a circular motion from a distance qhere we can at least observe our planet from?
It still wouldn’t allow you to go to a period of “time” of past events. “Time” is just a certain amount of units we measure daylight in dictated by the earths orbit around sun. Other planets have different “time” speeds. It’s truly a misconception when people say you can time travel. If you traveled 5 light years away and then traveled back to your starting point at regular speed, you’d be the exact same age the day you returned. A 40 year old man is still a 40 year old man whether he’s traveling super fast or not and he is still dead after 5 light years the same as the person on earth would be dead. Deterioration and aging is still a thing even if “time” travel is possible. Which it isn’t in the idea going to different places in history.
@@mountaineerdefense2507p
Says you but you are not God so you cannot say something is impossible
@@mountaineerdefense2507couldn't agree more, the only way to potentially 'time travel' would be in a cryptosleep casket. Where you would be perfectly preserved the way you are while the world changes around you.
No matter how fast you travel somewhere the only thing that would change is how quickly you arrive at your destination.
In my opinion, speed does not affect time. Traveling quickly through space does not equate to preserving time relative to another person; it simply means covering more distance in less time. Time is the same everywhere in the universe. It all ages at the same exact rate. Traveling at the speed of light would not cause you travel backwards or forwards in time; you're just moving through space rapidly. Where you end up will be the same time no matter where you are. If I were able to travel to the nearest galaxy instantly, there would be no time dilation. I would reach my destination at precisely the same time I departed from Earth, plus or minus a few fractions of a second, since even an instantaneous journey would involve a small measure of time. Though, if I came back to Earth a few seconds later, nothing would have changed on Earth except for the few seconds that passed during my trip.
Regarding light, it's true that we are, in a way, looking into the past when observing distant objects like galaxies and stars. This phenomenon occurs because of the time it takes for light particles to travel across vast distances before becoming visible to us. The time it takes for light to travel to us differs significantly from the actual time at its source. The light we observe may have traveled for millions or billions of years before reaching us, allowing us to see the universe as it was when that light began its journey. However, this does not imply that we can physically travel back in time. If a beam of light from a distant star reached Earth at this moment and you could instantly teleport to that star's origin, you would see the star as it currently exists, rather than the light we observe from Earth. The star you traveled to may not even exist anymore. Watching it feels akin to viewing an old black and white film. It's like reviewing a tangible record of events that occurred in the past but have since ended or changed significantly over time.
Also, consider how we use phones to communicate. If I'm in Texas and make a call to someone in France, we're speaking and seeing each other in real time for the most part. Though the speed at which our data moves may cause a slight time delay, we still exist in the same time. If I were in Texas and my friend was on Mars, there would be a time delay from data having to travel that far, though we still exist in the same time. I'd essentially be seeing a recording of my friend rather than seeing him in real time, but that doesn't mean either one of us has moved into the future and/or the past. Time is constant and moves in one direction at one pace, forward and steady.
There are deja vu experiences, but they are abstractions conjured by emotions. Still, they feel uncannily real!
I have a very basic question that I have wondered for a very long time. If I travel at the speed of light from earth. This would mean everyone on earth is also travelling at the speed of light relative to me. So how can my clock tick slower (or not tick at all) while Earth's clock tick normal. I mean why would time stop/slow down for me and not for Earth? Why and how would I travel in future in that case? I mean who is to say who is travelling at the speed of light? Since it is all relative?
You know it takes 0.13 seconds to go around the You're talking like it'd take minutes or hours to travel on or around earth at light's speed.
I like Doc browns explanation (basis in fact or not) of sending Einstein (the dog, not the physicist) one minute into the future, so that he skips over that minute, and reappears when Marty and Doc's (perception of) time catches up.
Always love those movies my son who is 37 now considers them his favorite movies!!
It's a movie so I went with it, but in reality I would think Einstein would always be one minute ahead of them in time. They can't catch up to him because he is one minute ahead of them.
Traveling at the speed of light is the most difficult part. Everything will seem stretched out and that'll make if almost impossible to physically locate where you wanna go in time. Unless the machine is preset to that particular place and time.
What type of materials on earth or from other planet or galaxy can we use, at certain speed not even closer to lights speed the item gets overheated then burn and explode
Time dilation is something to avoid with FTL travel, I mean you want to get home when all your loved ones are still alive or the entire human race for that matter.
So, faster than light without time travel.
I would love to go back in time to the creation of the universe. That would answer so many questions.
I would love to go back to when my children were still kids

Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an entire city complain about the same time paradox unless it was effected by it. Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're randomly given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? Ti-i-i-ime, is on my side. Yes, it is!
Maybe it's the weather? Maybe a local sporting event? Maybe a local news story? Depending on these events, being positive or negative could shape peoples perception of the day, not some time distortion.
Time goes by very fast when you actually are engaging in certain activities. My job is very fast paced and I have a lot of things to do within a short period of time. Being busy and NOT being busy, aka clock watching are 2 different things. You never hear of people complaining their sleeping time went too slow when they sleep 8 to 9 hours.
@@mikewolverton7904 If you can think of a better way to do a blind survey - of an entire city - in that small window of opportunity, well then, I'm all in.

Time flies when you're having fun. How true! However, this has nothing to do with time. It's a purely chemical reaction in the brain. All perception. Good example.....when you're running late trying to get to work on time. Every red light on the way lasts longer than normal.....It doesn't really. Every other driver on the road is driving way too slow........they're not!! It's just your impatient brain. Next time, leave the house earlier!!!
@@m.loughlin1915 see previous post. (9 months ago)
It's too difficult to imagine to time travel to the past. How do we travel back in time physically? How do we set specific day/time? Where on Earth will you locate? etc... First we must figure out how to travel to the past, then a million more questions to answer.
Which is impossible by science through itself.
Unless there are some supernatural powers or objects
Time traveling backwards is impossible. The Earth, Sun, all of the planets, the galaxy are all moving objects. They are not stationary. There is no rewind button. It's not just a matter of traveling through time, but also moving objects back into place. It just can't be done.
In other words, we can go forward in time from the present and the future would become our present, then we can travel back to when we left, making it our "past" but only at the time which was once the present we left.
i need to go back in time now more than ever.
Me too.
So are we really traveling into the future, or are we really experiencing time differently?
its the latter. Like if you took a boat trip that took days, versus a plane that took a few hours.
You arrived alot sooner by plane, meaning you aged less.
The theory is correct but the conclusion that its in effect time travel, is nonsense.
Two people racing on a track, have the same time ticking, one just arrives at their destination sooner.
Far as im concerned, you cannot travel and end up at the spot yo started, just because you moved fast
@@millyoneyedeaz1350 Have you considered a circular track, where the start and end are the same?
@@millyoneyedeaz1350 That's a good way of describing it. Though it kind of makes NDT's statement that we can time travel a bit incorrect.
I believe there is a theory that, with a block universe (past present and future all exist), you or something going back in time would have already done that, thereby solving the “grandfather paradox”. In effect, the universe and causality may be “protected” up until the point that a Time Machine is invented or, say, a black hole “time Machine” is used. But that just how I unrest and it. Isn’t the dunning Krueger effect awesome? Lol.
I thought The Dunning Krueger Effect was where people think that they are Know It Alls in stuff they have no idea about.
I feel like the variation of the theory of the block universe where there's no future but the past and present are a thing is more realistic.
I thought the grandfather paradox can be avoided because when you change time you return to a parallel universe
Its so fascinating to listen about time travel, thanks for such content. If there is indeed space time to be invented in future, it could be done outside Suns Gravity field where Voyager are travelling now. If somehow we get something stationary at Sun's Lagrange point and shoot anyone back to earth by heavy detonation to move anything back to earth from there, they could have experienced huge time travelling, if i'm not missing. Till next century humans may get that technology. Hopefully if survive.
Interesting what you wrote. Imagine that next century human has no choice but to travel in time in order to save humanity. 🤯🤯🤯
@@pavel514mtlQC Perhaps that's why there are UFOs observing us. They are just future humans trying to fix the timeline of the future.
and if humans survive to do so we can all see our loved ones again I guess
I WOULD GO TO THE PAST AND THE YEAR TWO THOUSAND
Pink Floyd explains TIME ,On the Dark side of the moon album. I'm staying with that explanation. Love and peace from Perth Australia 😎💕🖐🎶🎵🎶
I think that it is better to always be going forward.Sometimes we think of the past and have trouble moving on. If you were able to be with people and places from your past you may not want to move forward at all.I think that it would be a mistake to take our brightest minds and have them working to go backwards. Especially when they could be working to advance mankind.
Absolutely. Every time I go to sleep and dream about the past I’m going back in time using my very own personal Time Machine. 😆
Scariest thing is.... if we do eventually figure out time travel, why dont we have time travellers here now?
Either we never figure it out.
Or its kept under VERY strict use, in a way that nobody here today knows about it.
you probably cracked the code
Or it just hasn't happened yet because there is no future until we make it.
There would have to be very strict rules and likely limited use of the tech. Imagine if just anyone could travel back in time...they could mess up so much stuff. Many people would abuse it for personal gain.
Also, consider the time-traveler that actually goes to their past. Who would believe them if they tried to convince people that they were from the future? And if they did have tech or knowledge to prove it, then they would likely be captured and forced to help those in that timeframe understand future events/tech. They would likely keep quiet to avoid that...if they ever wanted to return to their point of origin.
I believe it's not impossible we've been visited but 99.9%+ of us would never find out because it would be very carefully and secretly done.
We like to dream of going back, but it usually implies being young again and avoiding the mistakes we made. I'm reminded of the old Twilight Zone episode "Of Late I Think of Cliffordville," which turns out rather badly for the time traveler.
I would love to go back in time and correct my mistakes! But if you couldn’t change your mind and make different decisions, then I don’t see the value of taking what seems like a risk.
Only thing that sucks about any possibility of ending up in the body of your former self to redo everything the "right" way is A) trying to work around any unreasonable members of your family in a wholly new way & B) changing the future enough to where you no longer have any precondition of what will happen next.
It is indeed possible to travel backward or forward in time, provided the space craft the passengers that are on board is powered by dilithium crystals to propel the conveyance to the chosen direction of destination. Should the craft experience dire malfunction during transit due to overheating, the auxiliary emergency power unit may always be engaged to carry on with the long arduous journey. 🤔
I have been diagnosed wth Huntington in 2010. I went through a series of unfortunate additionate events (for one, i have food allergic allergies after forgetting to take a medication).
Would love to return to 2009 to make things easier)
I wonder if this could be done on a "micro" scale instead of using light years and endless space (not knowing exactly where you will end up) but something much smaller where you could control precisely where you enter and exit the "wormhole" in question required to travel back and forth in time (miniature black hole etc)
A wormhole cannot be left at any point along its length. You enter at the entrance and exit at the exit. However, from what I've heard of the Tipler cylinder (not just this video), you can choose your exit point.
Doc Brown, in Back to The Future, illustrates why travel backwards in time hasnt happened, nor will it. Not only do we all live the same space time continuum, we all live the only space time continuum. Travel backwards in time creates a new continuum that, no matter how minisule in degree change, eventually becomes vast over time - erasing us all.
An example would be charting your course across the ocean for a distant lighthouse thousands of miles away. If you start your voyage 600 meters away, a minisule error stills lands you at the lighthouse. However, over thousands of miles this small error lands the Voyager nowhere close to the lighthouse. Indeed, the lighthouse would likely not even be seen.
Any interaction with the past, no matter how small or seemingly insignificant, changes the trajectory of time moving forward which, like the misguided seafarer, eventually removes earth from its destination.
In terms of paradoxes i believe the universe is what it is, we as humans give ourselves to much importance, so, to me, if we travel back in time we would just erase our original timeline but it wont destroy the traveller
But, yea, i dont know how the universe will justify that, for now you cannot create energy and matter from nothing because thats how you will be seen in this past universe.
so Doc Brown is wrong about paradoxes destroying the entire universe....or merely limited to our own galaxy?
Most folks (even geniuses)(genii?) neglect the first three dimensions when talking Time Travel (TT).
Somewhere else in Time is also somewhere else in space. Think anti-aircraft gunnery, you don't aim at the aircraft, you aim at where you expect it to be by the time your shell gets to it. To go back in time (or forward) even a week you'd find yourself gasping out the last of a suddenly abbreviated lifespan, in the cold vacuum of the cosmos ... so unless you can sort that one out you'd be (very quickly) not you but an ex-you.
There is a natural way of fast forwarding time........sleep.
You take a nap at noon. Your dream felt like 5-10 minutes, then wake up to 3:45.
If travelling in the past were going to be possible at any time even in the distant future, our future selves would have already visited us. 🤟
Maybe they have and just not made it known. They may think it’s unethical to tamper with time.
Maybe they only use it for tourism & every insane prson who thought they were being constantly watched were absolutely correct.
@@omniking9631 Or they know how fucked up we are today and won't come withing 1000 years of us.
@@omniking9631 It's impossible to not interact. Once they appear they have interacted. Just taking up space is an interaction. It's not unlike the simpsons episode where Homer travels back in time. Imagine you land in the Congo and you swat a mosquito that is bothering you. That mosquito was supposed to have bitten some child and given them malaria. The child was supposed to have died from malaria. They don't die now and end up becoming a great scientist or a horrible tyrant who starts WWIII. Any interaction with our timeline would either create a separate branch in time OR obliterate the future as you knew it
@@barongordo591 A travel back to time automatically creates a new timeline. Timeline intended to be visited before time travel still exists but is basically inaccessible to time traveler.
If the possibility of traveling back in time exists, there can be no paradox.
exactly
But if you have changed something, it creates paradox in an alternate timeline
@@emilyhopemeechem4183 wrong. Because time doesn’t work like that.
@@jbogy1 time should work like that if it’s possible
@@emilyhopemeechem4183 “if” just means speculation. The moment is all that exists so we should live in it. But think about this. If conservation of energy says nothing can be created or destroyed, just converted, then time travel would both create and destroy.
My theory is time travel into the past is possible and even if we changed something that happened in the past there is a way that things could work out without causing any paradoxes. For example, let's take the famous grandfather paradox. Let's assume that someone has traveled back in time and killed his grandfather. In that scenario, his actions won't be affected to his timeline or future. It will only make a branch alternative timeline, which is connected to the main timeline, where his grandfather is dead. In that way they all make sense.
See, that's not really how I interpret the multiverse or multiple worlds theories. I still think you are bound to your universe, allowing all the paradoxes to still affect you as long as you are stuck in your universe.
A branched timeline happens when you went back in time to make some changes
Time is not just a straight line but it’s natural
If you changed something in the past, then it would not affect the timeline we live in
Branched timelines depend on other peoples decisions for if one person grows up to start a family or dies young
If time is traveling in waves like in the water, that means past exist. Not only do the past exist in this scenario, also alternative worlds because new waves will form just like in the ocean. It goes and come back again and again etc.
Time doesnt tick slower. Time never changes. Us going faster and faster is just changing our speed, nothing else. Our observation is affected, but not time. Time is still ticking away the same throughout the cosmos. It doesnt depend on whatever we do. We never "look back through time" We see images of things that happened in the past. Can't touch it, can't change it, we just capture the image when it finally reaches us.
Correct!
i want see my child hood time early 90s
We know that by now
Title of the video : can we move back in the time?
80% content of the video: How can we move forward in time?
Because that’s easier to explain than going back
Because it is impossible to travel back in time. Traveli back in time means you set trillion planets and stars in universe backwards which is imposibble
Because it's just impossible to go in past buddy past doesn't exist because those things has happened already, talking about going ahead in time yes there are many possibilities to that .

My understanding of wormholes is that they are so unstable in theory that the mere act of entering it would cause it to collapse making it essentially useless for any kind of travel.

I travel back in time through music. I hear a record from 1956 in the year 2024 and my brain envisions a video with the sound which takes me back to the first time I heard the record in 1956. I reexperience the same feelings at each end of the time span. The fact of traveling so fast you end up in the future is just a theory. Who is traveling so fast they are hurtling into the future? Nobody!

We need to be able to travel at 10x the speed of light to time travel wormholes are too rare to rely on.
So rare in fact that not a single one has ever been found or observed anywhere else except on an astrophysicists black/whiteboard.
@@vallejomach6721 The Idea is to make the wormhole not find it, you need to look at Esinstine research more. But it is more from space travel than time travel, which should not be the focus of a wormhole.

You can go control the time factor all you want in reality... if you wanna go back in time, just think of a memory and there you go, right into the past... or if you wanna go forward to the future... just wait 1 second and there you go hahaha

@@SportsFan838 He is being philosophical vs intellectual in his response lol, like we as races repeat our mistakes in various ways until we finally learn.
Of course we can go into the future, we're doing it now. But backwards? .... Maybe in the quantum realm with retrocausality.
Causality is always maintained during time travel but only the traveler would see that.

I don’t think it is possible to physically go back in time, although I wish it were. If it was possible it would really mess things up. However, I do think it is possible to view the past. I really hope I live to see this come to fruition.
Thanks again that was very awesome to see
Cant tell me I cant go back in time...I just watched a recording/video you made 3 days ago. Now I'm commenting on it. Light and sound waves can be captured onto film and played over and over again....the past constantly being witnessed in the present. Half the stars in the night sky are dead, but ironically thier light still glows brightly. As for interacting will the past...what di you think I'm doing now or should I say was doing🤣
Best comment. Ive always said photos/videos are a form of existing time travel
@@Haildawn Light and sound waves are the key to witnessing ancient history. You cant undo or interact with it, but you can still observe its passing. Like I said, as our stars shine still- they have long since died. An interesting thought is a present day alien planet observing the light from earths past, seeing maybe the Roman Empire and thinking that's how life here is now in our present.
I can confirm that time travel is possible as I am from the year 2250 and through the theories explained here we were able to go back in time. This has proved useful as hopefully in the past we can prevent the current future from occurring as the lizard people have taken over and I was sent in the past to prevent them from taking control.
Are you ok?
@user-uu2uv8bw2s he says lizard people have taken over the world 😪
When you consider looking into this universe to go anywhere, is to travel back in time, and whatever your target is will no longer be there, so how does that work?
Time that has passed no longer exists.... You are constantly moving into time as it is created and passes.
The grandfather paradox is simple, if you went back and stopped your parents from meeting eachother it would change that timeline but not the one you lived, so you would still exist in your own timeline!
I feel like that is essentially the concept of being "in the eye of the storm." You are at the center of events but removed from the repercussions of time travel intervention.
The Many Worlds Theory.
If you could travel back in time. Would you experience an unending sense of Deja Vu? Since you would be putting yourself back in a point in time that you have already lived.
I think it depends on whether someone's age decreases to match the age they were in the past. Or are they relatively the same age they were when they began travelling to the past? In other words, are they able to observe a younger version of themselves?
You would run into your past self so you would have to kill your old self, and replace them. Then brings in the time paradox question, does killing yourself after traveling to the past change the fact that you already traveled to the past?
@@papasmurf205 no that's BS nothing will happen where do people get that theory from. but if you do end up killing yourself from the past then you from the past will not exist you will prevent yourself in the future in that timeline
Every time you sleep, your mind leaves the present, then travels in the future but your body advances through the normal flow of time. At wake moment, your body catches up with your mind. Time travel is not yet a scientific reality but it is a spiritual one. 🤭
That is what many Hindus believe with The Wheel of Time.
if going forward in time you need to go to speed of ligth, you need a positive speed, is there anything about negative speed? if there is a negative to every positive, should a negative speed of ligth can make you go back in time? and, will it be posible for a negative speed?
0:41 I think it should be higher gravity field not lower means you have to go to a higher gravity field

slowing your rate of aging or making your clock tick slower isn't traveling into the future. do you think the items in your freezer are traveling into the future? do you think you're traveling into the future when you go to sleep at night? As I see it, time is just the product of us keeping track of changes. it's not some dimension that we can travel through or anything can extend into. everything is very much stuck in the present. your claim of being able to travel into the future is limited to moving a few nanoseconds, a negligible about of time that is very easily inside any marine of error, if you travel at or faster than the speed of light, which is a very impossible feet.
So if I am 20 years old and travel away from earth at a speed of light, come back in one year to see all my friends of same age are now 80 years old instead of 21 because of time dialation. Would you consider that time travel?
@@jassisingh392 no. Slowing your aging is not time travel.
We are all moving into the future rather we like it or not. It’s a one way river that nobody can resist.
@@ScottJPowers I would disagree with you; If in one year relative to earth time I manage to move forward 80 years, I would consider it a time travel. But I guess you may be thinking about moving forward in time without traveling at a speed of light. I hope one day we might be able to it.
Your freezer analogy is not relevant. As you approach the speed of light, you don't start to age more slowly or experience time slowly (in your own point of reference). It is compared to others that you have aged more slowly and clocks have ticked more slowly. To me, that is time travel. Admittedly, it is nothing like Dr Who or Back to the Future.
You want to be careful going through wormholes. John Crichton went through one and his life was turned upside down. Two species that were warring with each other both chased him everywhere to get his wormhole knowledge. On the positive side of things, he hooked up with a really hot alien girl that sounded very similar to an Australian.
Time travel is impossible. Period
