Is time travel possible? - Colin Stuart

View full lesson: ed.ted.com/less...
Time travel is a staple of science fiction stories, but is it actually possible? It turns out nature does allow a way of bending time, an exciting possibility suggested by Albert Einstein when he discovered special relativity over one hundred years ago. Colin Stuart imagines where (or, when) this fascinating phenomenon, time dilation, may one day take us.
Lesson by Colin Stuart, animation by TED-Ed.

    Time dilation and time travel are not the same thing. Time dilation is real and that basically means that the RATE that time is experienced within a reference frame can be changed by simply traveling at a higher velocity. Time travel suggests that it's possible to instantly "jump" to any point in time in the past or future and as far as we understand it's impossible. The problem with the past and the future is that neither exists, the past has given way to the present and the future is yet to unfold.

    +dutchrjen I understand exactly how the Lorentz equations work and I was waiting for someone to mention the problem with "simultaneous" events. What I was trying to say is that even though light travels at a certain speed, past events are not preserved in the universe in a way that we could "rewind" the tape and revisit them. A record is kept through light waves and spacial distance, sure, but those are only photons. I'm also leaving out any wormhole theories and multiverse theories. Also, we consider the inertial reference frame to be the "correct" frame.

If you somehow positioned yourself 200 light years away and had a super accurate telescope and camera, you could technically see what was going on in 1820.

  • @willkettle4768

    This is a great question, but no. You won't reverse time. As you reach the speed of light, time will continuously slow down until it is infinitely slowed. If you go past the speed of light you need the time dilation equation (look it up). If you go faster than the speed of sound (140%) The dilation equation will give us a negative square root. This is when you will be in (imaginary time) and actually time will start to speed up until it's normal. So for an example if your ship goes at 200% of the speed of light and you take a one year journey, when you return to Earth only about 7 months have gone by. Hope this helped :)

    Time dilation is the change in perception of time relative to someone or something else. Time travel would be the ability to move back and forth. Sadly this is not possible because "time" doesn't exist, its a perception or measurement. Its an invention created by humans to understand the present. The past and future simply doesn't and never will exist.

If you observe a cell it multiply so fast right but if you observe milky way it move so slow... Cell move faster in our perspective because we are bigger while milky way move so slow in our perspective because we are smaller... Another example of time dilation based on how big/ heavy the object is... Ps this where some people based their theory about time traveling via quantum mechanics...

    I have a question about time travel. If you were to time travel, suppose, in 1990. And you went back to 1990 but the position of earth at that time will be somewhere else in the universe, because earth is actually moving and so is the solar system and so is our galaxy . So you will just end up somewhere in space and suffocate yourself to death. So isn't it actually a big risk to just time travel, you would have to travel through space too.

    +Osho SArAF Oh yeah, your time machine would have to have some sort of space-faring capabilities as well as time-travel. Because not only the planet, but also the galaxy would spin during your travels. You would end up way far away. (If you have enough power to time travel, though, flying across the solar system shouldn't be that huge of a deal.)The real trick is making sure you don't end up INSIDE a planet or whatnot at the end of your travels. Because then, there would be all of your molecules intersecting with all of the planet's molecules, and it might have a slight tendency to always explode horrendously.Moral of the story: time travel is more of a hassle than mere time travel.

    See but that's the thing, the future hasn't happened yet, we are the future, so until we go back and make it happen, we won't see any time travelers. We haven't invented it yet so therefore there is no way to go to and from, because it hasn't happened. Like in the video, time traveling wouldn't be just being able to go forward and backward, but it would be like you blinking and 10 years has passed because of how fast you were going in relation to space and time. You're not skipping anything, you're just hitting the fast forward button. You still exist in the universe, so your disappearance in the present would lead to your arrival in the future, obviously taking mere seconds for you, and however long the conversion is by how fast you are going is for them.

    Some ideas of time travel that I have read would suggest that travel would only be possible from and to the point in time where the first time machine was created. Say it was like wormhole time travel, and one end was set in the year 2020. There would be no physical time travel object existing before the year 2020, so this would be the earliest year possible to travel back to (and potentially, this date will be gradually moving forward also)

    To travel backwards in time, you'd need to invent instant teleportation between two anchors that can be physically carried around. Send one anchor into space on a round trip that turns around when it's 4 light years away, at a speed of, say for instance, 80% the speed of light. When the two portal anchors rendezvous on Earth, the one that stayed on Earth will have aged 10 years, but the one that went through space will only have aged 6 years. The two anchors will be close together in space, but 4 years apart in time. By entering the 6-year-old portal anchor, you will emerge from the other anchor 4 years ago. You have a working time machine, but you can't go further back in time than when you created the time machine in the first place.

  • @abeniang2923

    That wouldn't be time travel, you'd just have two teleportation devices with different ages. One 6 years old and the other 10years old. Let's say the year you invented both anchors is 2012 and you sent one out into space for 10years. It's now 2022, one anchor is 10 years old and when the other comes back, it's 6 years old. If you teleported between one to the other, the year would still be 2022. You wouldn't be moving through time, just space. Interesting theory though, there might be something to it as far as wormholes go.

It can easily become the most powerful weapon of any organisation that possesses it. “An entire city, completely altered by one e-mail......”

    It's theoretically possible to travel back in time, you just need to go so fast that you arrive in a location before you leave. It sounds impossible, but people have actually designed machines that can do this. Unfortunately, they cannot be built with current technology. Also, the only one that doesn't require materials we don't know how to procure, would span the width of the observable universe. I doubt we'll ever want to build that. So, in a way you're right; it is impossible to build one, but only because we'd first need to do different impossible things... That doesn't really help my case, does it?

And those quantum scales will not be strange and foreign to them as they are to us.

Maybe if we had a spacecraft which could reach incredible speeds and sent it to a distant galaxy or something and a large planet or star had enough gravity to change the direction of the spacecraft back to Earth, that could be cool. A person's year on the spacecraft could be decades here on Earth.

    I believe teleportation is the kind of word you are looking for. Well we don't even need light speed for that in initial stages, the main problem here is that its impossible to break or re-assemble human data as of now. Its trillions and trillions of units of information which even the best supercomputers today cannot handle. And even if we were to achieve this kind of scifi thing in the future we wont be traveling at the speed of light but beyond it in a way. Since the shortest distance between two points in space is not a straight line but instead its zero as shown in movies like event horizon or interstellar. :D

If you replaced that bouncing ball with the light beam (like they showed in the video), the shape of the photon's path would not be triangular like the ball's path, but instead, it would be straight back and forth, regardless of perspective. By simply moving horizontally in a vehicle, you cannot add this lateral velocity to a photon. It will always travel at C. Jack in his moving train will emit that photon from his light and that same photon will not bounce back in a triangular fashion, but in a straight back-and-forth motion, thus it will miss the higher mirror and continue its journey into space.. I need help with this one!

They have no reason to travel back in time because they know everything that has happened here. To solve that, what if we all of a sudden, stop recording information for a period of time like a week, and then come back, all of a sudden, with no indication of what happened? If they are anything like we are now, they would be curious on what happened and research and attempt to go back and find out. Then we would know for sure that time travel is possible. of course there is flaws, but eh thought experiment!

It is not travelling through time, when time flows forward. Yes, his time had flown more slowly, when compared to the time that passed on Earth, but he still went through all that time, not magically appear from one moment to another. If you like, you can tell that time flow is travelling through time. No it's not. It's travelling with time.

"It is not travelling through time, when time flows forward." that is completely wrong. even in your example, when someone "magically appears" at a destination, time has moved normally for everyone but the traveling person, so time still "flows forward". time has to flow forward in order for time travel to work. what you're talking about is velocity and how fast this happens.

(Of course, the spacecraft, along with the Earth & Moon, were all still orbiting around the Sun.)

    There is no way a human could experience the difference of time flow. We experience only our own time, and there is no way our mind could compare that to the time flow in other places. We experience every minute as a minute, but other people experience that minute as a minute too. It's not a difference in experience, it's a difference of test results. Tests say that less time passed in stronger gravity. But those guys can have no way to actually feel it in a way. Only after they see clocks that show different times, they understand that time did flow differently, but still they could not feel it.

    You are both wrong. What you have to understand is that, physics accepts as reality what can be observed and tested. In order to observe, you need to have an observer, which in the example given we have two observers. The problem comes when both observers have differente results from what it seems to be the same situation. This situation is much more complicated than it seems, it actually has everything to do with quantum physics. There are TWO results to the SAME experiment from TWO different observers, it all comes down to the question: "How can we know if we are the observers ?"

    Austin Geary There has been a lot of discussion about how motion must be determined. Relativity explains motion as relative motion to other objects. This is of course a bit problematic, because we could always argue about the relative directions. If you have water in a bucket, and you start spining the bucket, you'll see that: 1. The bucket is still, and the water is still. Neither move relatively. 2. The bucket starts spinning, but the water is still still. Now the bucket moves relatively to the water. 3. The water gains speed. Both the bucket and the water spin with the same speed. Thus, they have no relative speed. The water's edge rises up, and the middle of the surface goes lower. You know that. 4.We start to slow down. The bucket is still, but the water spins. The bucket moves relatively to the water, and the water's edge is still higher than the middle. 5. Both stop, water surface normal, no relative speed. Why does the water's surface change? It's not because of the movement, because the movement is relative. What if it's relative to Earth? Why would the water care about the Earth? Not to mention that the Earth spins too, and it doesn't matter to which direction you spin the bucket, the result is the exact same. This is why we must define something as an absolute space (or absolute space-time). This means that we can define specific points in the absolute space-time, and movement is relative to these. This of course means that the matter around these points doesn't matter. The defined points in absolute space time are completely still. We could define the points so that the distance between each closest points is always 1m. This means that their distance will always be 1m, regardless of what happens around them. They are not bound to London's map or anything else. When the space enlarges, the distance of these points remains at 1m. This is because the metre itself becomes relatively longer. This is why we perceive the universe to enlarge. If we take to distant galaxies that have no absolute speed relative to one another. This means that they are both still. Even so, we would still perceive the other galaxy as going away, because the space between the two galaxies expands. This means that the two galaxies have relative speed, but would that mean that the other one's clock would run faster? No, because their absolute speed, their speed which is relative only to the absolute space-time, is the same, zero.

    Jesse Heinonen Maybe I missunderstood your explanation, but the concept of "absolute space" is completely wrong. The principle of relativity, which is one of the base assumptions, that special realtivity is build upon, forbids any frame of reference to be "absolute". You can only define motion of two systems relative to one another.

He wasn't actually moving into the future faster then us we just were moving slower then him.

    creative M we aren't traveling through time, we are just speeding up time for us so that time goes faster inside our certain area so that it seems like we are traveling but we are just speeding up time for ourselves

    creative M,We are in the future now hahah, you get it, I bring you back to this comment because we are in the future from when you sent this comment a yr ago, so your first comment you sent is from the past, you get it now?

    creative M, see I sent my last reply to you 10 minutes ago, so that is in the past now, and I'm in the future from it, that is how time travel works,

    We don't know how to time travel but strangely we know the laws of time travel.

    i just had a doubt that jack and jill doesnt see the same speed becuase here comes the relative speed concept.........jil is seeing the ball move faster as the velocity of ball that jack sees is with respect to train that is 1.2 where as the velocity which jil sees is with respect to ground whcih is 4.2,so we can conclude that velocity of train is 4.2-1.2=3 that is jil is adding the velocity of train as well to the ball and jack is seeing the ball's real velocity that is 1.2 metre/s........hence we ca conclude that time taken by the ball to displace in the train is=distance covered by the ball in tain/real velocity of ball where as if we talk about jil,it is displacement covered by train+displaceent covered by ball in 1 bounce/4.3m/s

    Okay so instead of a man moving very fast in space for ten years how about we put a camera instead and watched it for ten years on earth and then it returned to earth would we see the future from the past?

    We would be seeing the time from our perspective. So say if the if camera traveled at 9 years at a super fast speed relative to our speed on earth, we would see 10 years of footage. The numbers arbitrary in my comment by the way.

    You can't return the camera from the future to the past, that's crazy. This is not really time travel, it's just that elements which move at a higher speed go faster through time, since time doesn't exist, it's actually all about movement.
