Brian Greene: Time Travel is Possible

Brian Greene:  Time Travel is Possible

We know a lot about time. We know that time
in some sense is at rock bottom that which allows change to take place, right. When we
say that time has elapsed we notice that because things now are different from how they were
a little while ago. That’s what we mean by time elapsing. But is time some fundamental
quality of reality or is it something that our brains impose on our perceptions to organize
our experience into some coherent framework that allows us to survive. I mean I can well
imagine that we have been under evolutionary pressure over the millennia to organize perception
so that we can survive, get the next meal, plan for the future. All of that would seemingly
require that we have a conception of time that we apply to what we experience out there.
But that doesn’t mean time as we experience it is real. It doesn’t mean that time as
we experience it is how the world is actually structured. I mean there are many ideas that
people put forward. The possibility for instance that, you know, we all know that matter is
made of molecules and atoms. Could it be that time is also made of some kind of ingredient?
A molecule of time? An atom of time? Is that really what time is at a fundamental level? Time travel is absolutely possible. And this
is not some sort of weird sci-fi thing that I’m talking about here. Albert Einstein
taught us more than 100 years ago that time travel is possible if you’re focusing upon
time travel to the future. And I’m not referring to the silly thing that we all age, right.
We’re all going into the future. Sure, I’m talking about if you wanted to leapfrog into
the future, if you wanted to see what the Earth will be like a million years from now,
Albert Einstein told us how to do that. In fact he told us two ways of how to do it.
You can build a spaceship, go out into space near the speed of light, turn around and come
back. Imagine you go out for six months and you turn around and you come back for six
months. You will be one year older. But he taught us that your time is elapsing much
slower than time back on Earth. So when you step out of your ship you’re one year older
but Earth has gone through many, many years. It can have gone through 10,000, 100,000 or
a million years depending on how close to the speed of light you traveled. And he also taught us if you go and hang out
near the edge of a black hole time again will elapse more slowly for you at the edge of
the black hole than back on Earth. So you hang out there for a while, you come back
and again you get out of your ship and it will be any number of years into the future,
whatever you want all depending on how close you got to the edge of the black hole and
how long you hung out there. That is time travel to the future. Now of course what people
really want to know about is getting back. Can you travel back to the past? I don’t
think so. We don’t know for sure. No one has given a definitive proof that you can’t
travel to the past. In fact, some very reputable scientists have suggested ways that you might
travel to the past. But every time we look at the proposals and detail it seems kind
of clear that they’re right at the edge of the known laws of physics. And most of
us feel that when physics progresses to a point that we understand things even better,
these proposals just will be ruled out, they won’t work. But I guess I would say there’s
a long shot possibility based on what we know today that time travel to the past might be
possible. But most of us wouldn’t bet our life on it.

  1. Hello Brian! I would like to go back in time. Can I bring Jennifer Driggers back alive. I haven’t seen her for over three decades now. I dreams about her all the time. I loves her so much. Can you please help me to go back in the past?

  2. There is no time . Time is an invention of humans to organize events because xucked up human brain has to organize everything , know everything and is always stupid anyway .

  3. Any scenarios that produce paradoxes will cause the worm hole to immediately collapse into a burst of radiation before traversing. The higher laws of the universe will prevent paradoxes. Worm holes and other methods of time travel are definitely possible it is just far more advanced, especially in energy requirements than what we are capable of. Another problem is the exotic matter needed isn't available right now.

  4. Brian is wrong, he is telling us that there is such a thing as determinism. The Bogey of Determinism:

    Let's suppose that determinism is true, that there is some set of human conditions C that are jointly sufficient to bring about an event a, in this case an action, which changes the movement of atoms in the universe. For anyone who knows the theory "C causes a," a is predictable from C. But now let's suppose I find out about this theory, and it is my action a that is in question. The set of conditions C is no longer complete, for there is now an additional condition – my knowledge of the theory "C causes a" – and so we need a new theory, according to which we can predict action a1, from the new set of conditions, C1 (C plus the fact that I know C causes a and the complications that brings about). Now let's suppose that one of the conditions included in C1 is the fact that I am a dishonest person, Accordingly we can be sure that in our new theory, a1 will be a different act from a, precisely its opposite where it is possible. But now we have a new theory, C1 causes a1," which takes into account this dishonesty and includes it as a variable in the theory. But suppose I come to know this new theory, thus adding a new condition to the set of condictions C1(C2), Out of dishonesty, I will now act in such a way as to falsify that theory, too. But, of course, a new theory would would predict that also, (as long as I don't find out about it.) Even if determinism is true, no one can know in advance what they are going to choose, not even a sufficiently "powerfull intellect." Determinism, then, is not an intelligble thesis. In other words, we can accept determinism without concern if we exclude humanity from the universe.

  5. I'm going to the edge of a black hole until my student debt is written off. See you guys in 3 space years when I become an unsolved mystery case.

  6. If I attempted to travel back to the past and it resulted in me ending up in a parallel universe that mirrors our own, except that its time is trailing behind the one where I came from I'd consider my attempt a success and still call it time travel back to the past 😆


  8. He sounded sad when he said it might not be possible. It kind of made me sad cause I too wish I could undo my own past

  9. It’s not possible to change time but it’s possible to change observation , stop believing this bullshit

  10. That's really good sir. Actually time travel is also possible through warm whole.and according to my own theory it perfectly explain s that space is like a sphere.l have made it.please l need your help and support to check out that . Will you help me

  11. Well Well Well. I wish to stop you when you said the Einstein said traveling with speed of light. The whole theory of Theory of Relativity is useless. I question to all mainstreamers, Dont you think when you with speed of light your spaceship will dissolve by extreme heat and friction and important thing you will have lot of debris, huge asteroids in space so it will hit your spaceship over there. By Mainstream we can never achieve time travel that everybody knows who witnessed the WW-II in the ERA of Sir Nikola Tesla, Wilhelm Reich. There is no connection between this Einstein and Time Travel he did not knew anything about it.

  12. We Are Time Travelers.. We Have trains,cars,boats,plains,and More .. We calculate Time … Watches..Calanders.. we have a GreaT Concept of Time .. And space .. Even Traveling through time u have too have Knowledge of space they go Hand And hand .. ..and there are Many ways Too Time Travel.. .. ..More then people think .. We Have I believe already made time machines just not in this year .. we Hummans Will Go To any Extent Too Make Things the way we want them too be ….✌😎.. .. 🖖😎

  13. What if we invent a teleport machine and put it on intersteller and send it to another hebitable planet @ the speed of light. We can achive 2 things, teleport to another and to the future…

  14. Here in New York City my head is spinning since you said is time a molecule or ingredient wow looking at the sky wondering

  15. Who the fick wants to travel to the future? Let's travel to the past and change some things. Seriously. Then we can look forward to the future

  16. what if I have sensed some sort of time travel skills, putting the vibration tune in a cosmic accordance to make things different at my present time. What should I do with it Skill up practice where…I was in the shop and it was a bit strange 3xentered the shop physically 100% Halfords Paisley Glasgow Scotland but to just collect a parcel It took me 1hr,

    1st entry Me just like everybody else – Stay in the line and say Am here for collection, didnt have it so by name couldnt find the parcel anyway So the guy says if you can get the from my mobile so went back again.

    2st time in the shop. Talking to a different guy giving him the 10digits no. out of my head the guy goes in the computer go to the safety case he cant find then I turned around and he just went to the warehouse for some other things…

    I said this is a bit coo coo land, 5 or 6 guys in the shop everybody is running like a head less chicken but then I left the shop went back to my car where my girlfreind waited and told her to wait this is my 3rd time to eneter the shop but this time something took me a bit different, I forgot about what I came for walked about and then I sat on the bicycle display one and started pedling with it and electric motor attached, the motors started to wizz sound and the frequency of this started to adopt and tuned the surrounding by which I could speak and operate very easy around people and them were very keen to tune in to make everything smooth.

    Then in McDonalds I went to the toilet and the guy was just leaving, So I was washing my hands and then another guy coming in and took a cabin next to mine where washing hands Didn't like it at all, so when finished washing hands wend to the other side where the hand dryer is and started to switch on and off by distancing my hand from the dryer The frequency created started to tune up of the frequency of the surrounding and all suddenly changed…

    Now I practice counting by seconds, Last night when driving down in town I had this feeling like one next to the Clock Tower on the right some restaurant gave me the feeling of portals to another dimensions.

    I got more coming…

  17. I also went for a MRI 7T scan and those sounds correct or guided my brain in the different life path

  18. That's not time travel, that's just skipping time. Not even leaping, but skipping. Because u could never go back to the time of your origin.

  19. Impossible! And it's like a hypothetical science-fiction character who goes backward in time and gives birth to herself. #Deluded

  20. I think time travel is by building and creating a machine or some sort of a object that will take us to another time and place. I think I have the answer to time travel.

  21. I believe:

    1. The answer to time manipulation lies in the understanding of the behavior of empty space.
    2. The reason entropy exists (eg. universal aging) and that theoretically we can "time travel" when traveling at the speed of light is that we slow down the interaction that empty space has on our torus fields, reducing our relative entropy to a minimum, thus reducing energy movement.
    3. If we understand how empty space behaves, we are on the path to some sick shit.

  22. For time travel to be possible, there would have to be some sort of time-data. Think of it as a camera. When you use it, say to take a picture of a tree, the picture or data is saved on the camera, or more detailed the sd card. the sd card holds the data. If you place the card in a camera, you are able to look back to the tree, right? I would think, and this is just a theory here, that this is the key. Boom. If we, somehow, made a time-recorder that recorded every second of every day, we might be able to use it as an sd. Like, go back to the picture. Or time in this case. And even so if this was possible, we would not be able to go to the past. Think of it, can you look at a picture that you haven taken? No.
    Just a theory

  23. I don't care about future, I just want to know whether it's possible to go back in past or not?

    Because if not then my future is already doomed.

  24. Just because einstein said it doesn't mean its true. Go out n travel at the speed of light and then come back and see how many earth years really went by

  25. To travel to the past, go faster than the speed of light, underground. Think particle accelerator but for a person instead of a particle.

  26. I would rather travel into the past than the future. The future sounds boring but the past is an experience of a life time.

  27. Time travel backwards is possible. All you have to do is bend light into a loop. I dont know why we dont fund these things. They said man would never fly, and a hundred years later we landed a man on the moon. "We do these things not because they are easy, but because they are hard." Once mankind decides we WANT to travel through time then, and ONLY then will we time travel become more than science fiction.

  28. There is no point traveling into the future through space then come back just to see how life on Earth has changed! Unless you really want to jump and into the future but you won't know what the future holds, but Bible does takes us into the future it says that our Earth and everything on it will burn Peter 3: 10 says But the day of the Lord will come like a thief, in which the heavens will pass away with a roar and the elements will be destroyed with intense heat, and the earth and its works will be burned up. So when you come back from your sweet light speed travel you'll come back to a burned up earth destroyed earth! The Bible says this cursed earth along with the present heavens will one day perish. They will perish, but you endure; they will all wear out like a garment. You change them like clothing, and they pass away. Psalm 102: 26 so there is no point of doing these guessing games and trying to figure out if time travel is possible even if it is it is useless since God has already laid out our destiny and our future and no humans or anything can change that. But those people who believe in God and his word will enter into new Earth and new Heaven. For I am about to create new heavens and a new earth; the former things shall not be remembered or come to mind. Prophet Isaiah 65: 17 Jesus said to them, "I tell you the truth, at the renewal of all things, when the Son of Man sits on His glorious throne, you who have followed Me will also sit on twelve thrones, judging the twelve tribes of Israel (Matthew 19: 28). When humanity sinned against God, the earth was cursed. And to the man He [God] said, "Because you have listened to the voice of your wife, and have eaten of the tree about which I commanded you, 'You shall not eat of it,' cursed is the ground because of you; in toil you shall eat of it all the days of your life; thorns and thistles it shall bring forth for you; and you shall eat the plants of the field Genesis 3: 17,18. The Bible says this cursed earth along with the present heavens will one day perish. They will perish, but you endure; they will all wear out like a garment. You change them like clothing, and they pass away Psalm 102: 26. The prophet Isaiah recorded God promising a new heavens and a new earth. For I am about to create new heavens and a new earth; the former things shall not be remembered or come to mind. Isaiah 65: 17 The glorious promise of God is that this earth will be made new. This will be a reversal of the curse of Eden. Jesus spoke of the renewal of all things – the time when all things are made new. Jesus said to them, "I tell you the truth, at the renewal of all things, when the Son of Man sits on His glorious throne, you who have followed Me will also sit on twelve thrones, judging the twelve tribes of Israel Matthew 19: 28. Who [Christ] must remain in heaven until the time of universal restoration that God announced long ago through His holy prophets Acts 3: 21. The Bible says God will make all things new. And the one who was seated on the throne said, "See, I am making all things new." Also He said, "Write this, for these words are trustworthy and true" Revelation 21: 5. The present order of creation will be replaced. In this new order, the only people who exist will be God's people. They will live in the closest of relationships. Those who have not trusted God's promises will not take part. But as for the cowardly, the faithless, the polluted, the murderers, the fornicators, the sorcerers, the idolaters, and all liars, their place will be in the lake that burns with fire and sulfur, which is the second death. But nothing unclean will enter it, nor anyone who practices abomination or falsehood, but only those who are written in the Lamb's book of life Revelation 21: 8,27 Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea. Revelation 21: 1 The new heavens and earth are different from the period of the Millennium. They will replace the old cursed creation. Nothing accursed will be found there any more. But the throne of God and of the Lamb will be in it, and His servants will worship Him Revelation 22:3 But by the same Word the present heavens and earth have been reserved for fire, being kept until the day of judgment and destruction of the godless. But do not ignore this one fact, beloved, that with the Lord one day is like a thousand years, and a thousand years are like one day. The Lord is not slow about His promise, as some think of slowness, but is patient with you, not wanting any to perish, but all to come to repentance. But the Day of the Lord will come like a thief, and then the heavens will pass away with a loud noise, and the elements will be dissolved with fire, and the earth and everything that is done on it will be disclosed. Since all these things are to be dissolved in this way, what sort of persons ought you to be in leading lives of holiness and godliness, waiting for and hastening the coming of the day of God, because of which the heavens will be set ablaze and dissolved, and the elements will melt with fire? But, in accordance with His promise, we wait for new heavens and a new earth, where righteousness is at home 2 Peter 3:7-13. When Adam and Eve sinned the earth became cursed. God promised to destroy the old earth and make something new. The future home of the believer will be in the new heavens and new earth. After the final judgment, God will remake the present universe and form a new one – a universe without any remembrance of sin. Though the exact relationship between the old and the new is not entirely clear, it is clear that the new universe will be without sin.

  29. Not sure why anyone is hung up on light speed, it's incredibly too slow. If we ever want to get anywhere, we need to ditch the old school concept or physical travel and speed and start thinking interdimensionally.

  30. we can't go to the past because we would make of 2 of ourselves and also we can only go to the future because we only need the speed of light. Also we can't interfere with the past since it happened unless we interfered with the continuim

  31. we re paused so we time travel to future
    outside world keep going

    could be test by transfer the thing near speed of light…
    and human inside the thing(shirt?)

    reverse engineer human back to past

  32. The "time is a man-made illusion" theory is actually stupid. If it is an illusion, we can look back or forth in time by carefully designed experiments. We cannot. Therefore time is something outside ourselves, a fast movement in spacetime that cannot be stopped.

  33. People none here including the guy in the vide knows what time is. Allow me to open your eyes a tab. Time is a construct of this world we live in. Outside of earth times not now heres why. In the garden our first parents walked with God. They were righteous in God's mind. There wasn't any time they were immortal. Then they sinned and hence forth placed under a restraint for they would surely die just a matter of time. You should be able to see where I'm going.nIf you understand its so simple. Every Child born from the moment Eve sinned all were dealt a death sentence. Nothing mysterious.

  34. The answer is: einstein said that time is nothing more than an illusion. and you can manipulate time because it is an illusion but we would never know because time manipulate our brain the same way how illusions make us crazy.

  35. we are in a time travel right now it was made possible by the particle collider or accelerator in cern they went to the further. Yet they forgot about the retard factor and that would be me.I do not fit in your reality I live in the years 1962 so when doing that I reset the partial accelerator and I act like a troll,Do not ask me how it happen I DO NOT KNOW IT JUST DID.that the same thing my Xwife said happen when she spent the night at a mans house.I ask her how why and how did that just happen. She said it just happen.right her cloths fell off and they started doing it.right.same thing it just happen.Rev> biible vers.look it up your self..Satan does something that nobody has never done and that is time factor.he trying to find a way so he does have to go to jail,And jail is near to him and he just has a short time.He trying to make his time longer on death row satan is going to!!!!! HELL is bedevilment for him.It looks like he slip away for death row he did not go for.With one day with the lord Jesus Christ is a 1000 YEARS so that means satan did not go for.we will find him MY blood hound ready on his trial.He not going to for and then throw that no good POS into HELL.

  36. “…let me tell you a secret: Some of the remarkable people you meet in life are time travelers. A few of these people know it; the others time travel without realizing it, but they do it just the same. These are the people who appear older than their years or, yes, often enough considerably younger.”
