I think that it's not so much a case of "when the time machine was built", rather when the time traveler left. He could leave Earth today.. spend a few hours near a black-hole tomorrow, and look back at what has happened since. This means, in essence, that only forward travel would be possible but no laws of physics would be broken.
wait, this might sound dumb considering the fact that i am a bit fuzzy on quantum physics, relativity, space-time and all that, but, if a worm hole is basically i tunnel through one part of space time to another, wouldnt it just be easier to 'move' the wormhole to the time and place you desire? or is there some law of physics that i forgot? and i have a question, how do the supposed subatomic wormholes pop up? does quantum physics allow for ANYTHING to happen as long as it doesnt defy physics?
We don't currently understand wormholes; they are only theoretically possible if we follow Einstein's theory. If his theory is correct, however, it would take near infinite energy to prop one open, much less move it.
@newscientist Now for wormholes, the main thing you forgot is the educational aspects of wormholes that allowed use to first consider time travel. Historically speaking (especially if you know the work of Carl Sagan influence), wormholes (as well as black holes too) are the great graphical metaphor created to help us understand General Relatively and teach GR. This is true even if wormholes do not exist. From this educational process with researcher is from which time-travel holes.
@newscientist For example, going back to the black hole collision, black holes are not truelly violent because it simply large mass shifts. Those mass shift really only change small pertibuations in orbits, new orbits, lensing to shift slightly, etc... so its like a thousand trees fall simultaneously, its a large shift that has a very small observable effect compared to the observable effect of what we used as candles.
@newscientist Futhermore, . For example orginally research who developed the model for equal mass black hole collisions and the research team who detected kind of felt slightled that they only focus on the metaphysics of black holes colliding and it meant instead of the actual research and the physical questions they where exploring. In fact, it created the common myth that actually black hole collisions are violent.
@newscientist After considering this article, I am still disappointed thought not for the same reasons. Normally I don't associate NS with pure theory; however, the main reason I was upset at this video was it really took things to one extreme of how the media and scifi likes to portray time travel instead of highlighting some of the interesting educational breakthroughs in the concept of this like wormholes.
If this goes to reality, which means that this technology would be totally use for wrong intention, what if we get terrorists that likes to terrorise the past and the future?.
What about traveling back to WW2 to chance everything?, thats a dangerous task.
So what if you travel trough time and you want to go back and you noticed that youre not really back in your own timeline, but rather a timeline that copies itself?.
Which means that You have 2 same individuals with the same motives.
In short you see yourself and the other person doesnt understands whats going on. Something into a much deeper plot of a complicated situation Which is fucked up!.
Time travel.. just seems impossible. Lets say it were possible to go back in time, wouldn't the energy requirements needed to change every single subatomic particle back to the state it had been previously (and somehow have knowledge of that state) throughout the universe be beyond the capacity of just a few thousand stars, and the knowledge of mankind?
Or perhaps time really is bottled, and there are an infinite amount of universes stored out there suspended in time that we can traverse??
wow telling people false info..i don't think his theory his you can go back in time..it does says..you can go in the future...stephen hawking doesn't says you can go back in the past...
A human is just a human. Science will only go so far before something "unreasonable" happens that makes everyone scratch there heads (such as a person who can teleport themselves by thought). In truth, teaching a human "end game physics" is like teaching a termite basic math.
"Dark Energy" is not the same as "Negative Gravity." When dark energy drives the universe to expand, it is the space itself that's expanding, not that things are being pushed away.
Steven Hawkings had a time travellers party in his house made it a public event saved it to some important records and documents in the national archive so future generations can view it. Needless to say no time travellers turned up. Maybe records in the national archive get destroyed in 1000 years time who knows but needless to say I remain skeptical.

Clearning new scientist would rather support the FICTION of sci-fi lovers and the lack of physics in conspircacy theorists than give an article that is ground in legitimate scientific speculation. (at least wormholes where an actually metaphor for teaching before scientists even tried to take the idea seriously).
This article give an improper understanding of proper time in dealing with black holes. Time for the observer is falling into the hole not actually slower. You disappoint me Newscientist. Do YOUR RESEARCH!
If you "move" the end of the wormhole through space then you'll just end up back in that spacetime. There is no reason to assume the time dilation follows the wormhole exit.
Also, sending anything through, even at the speed of light, will simply emerge from the time dilation and return as it does now anyway. Time is not captured, it is a dimension.
Causality is not affected in both cases. There is no reason to assume the tunnel itself travels differently through time to everything else.
this is freezing time... not time travel.. u cant revers what happend to a matterial.. at least some of them like coal for example.. ur in the same place but things get different.. u should either un do everything without effecting the whole universe or just jump into some other excistance where things havent happened yet.. which is just crazy and not possible..
One thing that I don't get is how does it happen, that the wormhole holds the time difference after being moved from the black hole. May be I'm wrong, but I think of it as some kind of a high-speed-tunnel. The result of travelling through would be than the same as taking some high speed spaceship...wouldn't it?
@ojik I don't really follow your analogy, ...and I don't really agree with your reason either...but the wormhole itself is really nothing special. Just think of it as a really good short cut from point a to point z, instead of having to go through point a to b to c...ect. all the way to z. What's really special here is what the wormhole has allowed u to do, its allowing u reach places (that otherwise would be impossible) before you are allowed to reach them by any other means given the time.
@BullShitThat OK, I haven't known that...but that doesn't explain my point. Or am I missing something? Let's say, that all the technical issues needed for the "time machine" are solved. Wormhole entrance A is at Earth and Exit Z is at a black hole. The issue is, that when you move Z from the black hole, would the wormhole still cause a "time travel"? I think, that the wormhole's end "adjusts to the local time", so after moving Z, the "time travelling ability" of the wormhole is lost, isn't it?
So... Theoretically, the person coming up with the correct idea could spark someone / thing so far off in the future, to return to him and tell him he had the right idea?
What if time flows like one perceives it? As in, you can go back in time to kill yourself, without the murderer-you being "killed". Time may not be as continues as we assume it to be.
@XecodaSempai Actually you don't have to be at the black hole area, you "just" need keep one of wormhole's ends there (to get the time difference) and than move it to an area where you wanna travel to. Assuming you already got the other side of the wormhole ;-)
@XecodaSempai I've got no idea, but if you had a really long grappling hook immune to gravity and were experienced in throwing a lasso, than may be... :D
Wouldn't all this also depend on a view that time in the future doesn't yet exist, so that you can only go back in time and not into the future? Otherwise you'd think someone from the future would have already gone back to our present or past.
"Time travel" isn't the same thing as going more slowly forward in time. Remember - we're all time traveling right now, going forward in time. By definition you have to go BACK in time or else freeze your own time to make any sort of head-line news. Living on top of a tall mountain will cause you to age a tiny bit slower then people living in the valley below - not that a millisecond compared to everyone else is going to do you any good when you "eventually" die.
The video is misleading. We can move into the future, but thats trivial, we do it all the time. Nothing described in this video allows moving in the opposite direction, yet the video implies just that. Thumbs down.
Come on guys your better then this Theoretical Science is sort of the fantasy side of science with a bunch of what if's and depends on unknown hypothesized factor and a key one to making it possible just was discovered to not work in the favor so practical time travel has been proven not to be possible sorry it sucks we all cried inside that day. Sure if something can stand the speed it will slow a bit and seem to it less time has passed but for others they see it in real time. :( grrr
This is a whole bunch of bullshit. Contrary to what this "new scientist" video is telling you there is not a consensus on how time works or that it can even be traveled "in" Time is NOT a dimension for "travel" Also, Worm holes dont exist and there is NO way to negate gravity near a black hole. This isn't future science, this is impossible.
@ataraxic89 Actually both Michio Kaku and Stephen Hawking have both written books and come up with mathematical formula explaining why at least the physics behind time travel seem feasible. If you disagree though, you could always go out and study physics and try to create a formula that disproves theirs. Otherwise, why should anyone take your word over theirs when they've been studying and researching the field of physics most of their lifetime?
@ataraxic89 wormholes do exist, they're just tiny. And the video never actually said they did exist, they said that the current laws as we know them would allow the existence of them/
and what? why do we need to negate gravity? just orbit the darned thing for a while.
@ataraxic89 this is alll based off theories that make the most sense, (as in the big bang) we dont know for sure how it happened but its the one that makes the most sense and in general thats how science works untill you have the tec. to prove it, why u haten so hard nigga?
@WilloJohneme im hatin so hard cause its a bunch of bullshit. I know how science works and they are acting like this is fact when its not, its a lot of unproven conjecture and its misinformation.
@ataraxic89 point takin on how they are providing it as facts, but are u one of those people that think evolution shouldn't be taught in school because it's not 100% proven fact and their are holes in the argument? i thought it was a cool video personally showing a cool idea and it was also somewhat inspiring as to what the future might one day hold
@WilloJohneme No no, Quite the opposite. I love science but time is still very very very misunderstood. We shouldn't be presenting it as fact when literally the very concept of time is challenged. By the way, evolution is virtual fact, so of course I want it taught. However, time is not fact. I know that sounds weird but there is no proof of time in the "4th dimension" kind of way. There is no mechanism of the universe to "remember" or "predict" and therefore there is only the present.
Timetravel? Just go somewhere they don't have as much cash as you do. Hell, you don't even have to go to another country as far as I'm concerned. Visit my grandparents for a neat timetravel.
@miroradev I think you can only travel back to the point of the 1st worm hole ,so we are to early in time for you refutation to be valid , I think lols head hurts
Why do people bother to watch a video if not to pay attention to it? ... and then proceed to ask questions on the video that they didn't pay attention too.
This logic makes my head hurt far more than any science video could.
What if there are laws enforced on time travel, in the future? What if they didn't see the point of sending a message, or they were killed or something? lol Time is funny.
@miroradev no because as it states in the video, you can only travel back in time to the moment the time machine was built. no one has built one before, therefore no one has traveled back in time.
Also, if we somehow did discover a law of physics that allowed time travel to any point in time, why would they ever care about 2011? or anytime before that? by the time they actually discover time travel, it could be the year 3446 for all we know.
@mooer007 well they could have given us the time travel technology in advance and encrease the rate at whitch our technology developed so in the future technology would be even more advanced
@miroradev what you don't understand about time travel is that you are not rewinding time, you are traveling through it. If they come back in time to help out society for the future, they wouldn't because if they did then it would have already happened to them and they would already be advanced. It's a paradox.
@miroradev Hmmm I wonder though caz if we were to look at it from the future civilization's point of view would they really bother coming back to talk or even educates us? It'd be like us going back to premedieval time and tell them that witches are not real and that there are more than 4 elements. Not sure why you'd do that given the level level of cultural difference and understanding - it'd be awfully frustrating and infertile. Getting ridicule by people who er know are wrong would kinda suck
@sdejanip well it would be annoying but its at this time that we belive time travel is possible and therefor we would believe what the people were saying (if they show proof of course) and you do know how many great people were thought to be witches and possesed by demons the church at that time held back science by a 100 or so years... im saying we would have had the ipod 7 by now insteed of 4
@mechachomp go back in time to when the time machine was buildt and tell the person to in 20 years go back in time and tell the person to in 20 years go back in time and tell the person to in 20 years go back in time and tell the person to in 20 years go back in time and tell the person to in 20 years go back in time and tell the person to in 20 years go back in time and tell the person to in 20 years go back in time and tell the person to in 20 years go back in time and tell the person
@miroradev did you (and anyone else making a stupid response to you) actually watch the video? the time travel it is suggesting cannot let someone travel before the "machine" was built. if we do someday do the process in the video, say, in the year 2100, it can't possibly allow someone to travel to 2099 or any time before it.
@miroradev You didn't watched the video. It says you can't go further in the past than the time the machine was built. If we build one at year 10.000, we can go from anytime after 10.000 back to 10.000, but never before 10.000. But anyway, I doubt we ever will build a time machine that can send more than some particles to travel time.
How do you know that we haven't, our languages evolve at such a rate that in he future just a few thousand years from now our entire civilization will be completely changed. Perhaps crop circles are one such message. neeeww neee neeww neeeew......newww neee newwwww........ (0)_o
@W4rD0g72 cuz were still speaking different languages we are still at the very base of outerworld knolage and if we could build a time machine surely we could cure cancer
I find the idea of creating a paradox absurd so if time travel is possible then there must be a force which imposes a fundimental limit which prevents this from happening by limiting TT ability, moving you to a place where you cannot effect the chain of causality up to the point where TT began.
So if you traveled 1 LY you couldn't go more than 1 year back in time or it would be possible to create a paradox.
Greetings 2011 youtubers. I am from the year 2376. Archaeologists recently uncovered ruins of what they call "The United States of America." I came back in time to do a report for school on this lost civilisation.
No one ever talks about the distance. If you travel in time the Earth will have moved millions of miles but that's a whole other comment... The myth of the speed of light being a barrier has been around for ages when the proof it's a myth is right in your face. Gravity. If the sun disappeared you wouldn't see it go for 8 minutes. The gravity would be gone instantly. Apparently I never invent time travel in the future because I haven't come back to visit me and give myself better advice.
@crashlight1 no thats not true, the gravity would also take 8.33 mins to travel 1 AU from the sun's disappearance to the Earth, for us to notice the difference. No information can propagate faster than C, it falls straight out of the Lorentz transform equs... this is why nothing can moving faster than the speed of light.
@BullShitThat That sounds good in theory however as most engineers know theorys/equations get close most of the time, reality is a little different. I personally lean more toward gravity having "instant" propogation. Are you saying the LHC guys have misred their data?
@crashlight1 1st off there seems to be a bit of confusion going on here,...physicist have known for decades now, that gravity is not propagate instantaneously. (If it did, things like gravitational wave detectors would be useless) This includes the physicist at LHC, there's NO data that has ever shown other wise. You either must have miss read an article, or misinterpreted what they were saying, If this is not the case please provide the credible source, from where you're getting this info.
@BullShitThat Gravity propogation at speed of light is still a THEORY. It even says so in the Wikipedia article, and I quote: "Gravitational radiation is THOUGHT to travel through the Universe at the speed of light..." and " Various gravitational wave detectors exist. However, they remain unsuccessful in detecting such phenomena." Maybe if a detector can't detect it it's not there and so far gravity wave detectors have been useless.
@crashlight1 PART1. Just because something is a theory does not take away from its validity, in fact 90% of modern physics can still be consider a theory. Gravity propagating at the speed of light in particular, is a VERY GOOD theory; one that fits perfectly with our well founded understanding of physics that has been proven right, time and time again, through rigorous tests and experiments. ...
@crashlight1 PART2. …If this were not the case we would not only have to rethink our view of gravity, we would also have to and disregard some of our best theories today, throw out 1000s of text books, rewrite the standard model, explain why it was the case then but not the case now, and the list just goes on.
I far more inclined to believe in a theory that fits perfectly with all that we’ve ever known as humans, than a theory that is completely the opposite of this case.
@BullShitThat Well at least we're agreed it's still a theory. I'd be happy to toss all text books for the truth wouldn't you? Hopefully our research will someday end in an answer. Of course if we all agreed on everything how boring that world would be. If you're right I'll buy you a beer and you can take your time to enjoy the gravity of it.
you will be amazed.........

One thing that I don't get is how does it happen, that the wormhole holds the time difference after being moved from the black hole. May be I'm wrong, but I think of it as some kind of a high-speed-tunnel. The result of travelling through would be than the same as taking some high speed spaceship...wouldn't it?
ojik 3 months ago
@ojik I don't really follow your analogy, ...and I don't really agree with your reason either...but the wormhole itself is really nothing special. Just think of it as a really good short cut from point a to point z, instead of having to go through point a to b to c...ect. all the way to z. What's really special here is what the wormhole has allowed u to do, its allowing u reach places (that otherwise would be impossible) before you are allowed to reach them by any other means given the time.
BullShitThat 3 months ago
@BullShitThat OK, I haven't known that...but that doesn't explain my point. Or am I missing something? Let's say, that all the technical issues needed for the "time machine" are solved. Wormhole entrance A is at Earth and Exit Z is at a black hole. The issue is, that when you move Z from the black hole, would the wormhole still cause a "time travel"? I think, that the wormhole's end "adjusts to the local time", so after moving Z, the "time travelling ability" of the wormhole is lost, isn't it?

@XecodaSempai Actually you don't have to be at the black hole area, you "just" need keep one of wormhole's ends there (to get the time difference) and than move it to an area where you wanna travel to. Assuming you already got the other side of the wormhole ;-)

Wouldn't all this also depend on a view that time in the future doesn't yet exist, so that you can only go back in time and not into the future? Otherwise you'd think someone from the future would have already gone back to our present or past.

"Time travel" isn't the same thing as going more slowly forward in time. Remember - we're all time traveling right now, going forward in time. By definition you have to go BACK in time or else freeze your own time to make any sort of head-line news. Living on top of a tall mountain will cause you to age a tiny bit slower then people living in the valley below - not that a millisecond compared to everyone else is going to do you any good when you "eventually" die.

This is a whole bunch of bullshit. Contrary to what this "new scientist" video is telling you there is not a consensus on how time works or that it can even be traveled "in" Time is NOT a dimension for "travel" Also, Worm holes dont exist and there is NO way to negate gravity near a black hole. This isn't future science, this is impossible.

@ataraxic89 Actually both Michio Kaku and Stephen Hawking have both written books and come up with mathematical formula explaining why at least the physics behind time travel seem feasible. If you disagree though, you could always go out and study physics and try to create a formula that disproves theirs. Otherwise, why should anyone take your word over theirs when they've been studying and researching the field of physics most of their lifetime?

@WilloJohneme No no, Quite the opposite. I love science but time is still very very very misunderstood. We shouldn't be presenting it as fact when literally the very concept of time is challenged. By the way, evolution is virtual fact, so of course I want it taught. However, time is not fact. I know that sounds weird but there is no proof of time in the "4th dimension" kind of way. There is no mechanism of the universe to "remember" or "predict" and therefore there is only the present.

@miroradev You didn't watched the video. It says you can't go further in the past than the time the machine was built.

But anyway, I doubt we ever will build a time machine that can send more than some particles to travel time.

I find the idea of creating a paradox absurd so if time travel is possible then there must be a force which imposes a fundimental limit which prevents this from happening by limiting TT ability, moving you to a place where you cannot effect the chain of causality up to the point where TT began.
So if you traveled 1 LY you couldn't go more than 1 year back in time or it would be possible to create a paradox.

No one ever talks about the distance. If you travel in time the Earth will have moved millions of miles but that's a whole other comment... The myth of the speed of light being a barrier has been around for ages when the proof it's a myth is right in your face. Gravity. If the sun disappeared you wouldn't see it go for 8 minutes. The gravity would be gone instantly. Apparently I never invent time travel in the future because I haven't come back to visit me and give myself better advice.
crashlight1 3 months ago
@crashlight1 no thats not true, the gravity would also take 8.33 mins to travel 1 AU from the sun's disappearance to the Earth, for us to notice the difference. No information can propagate faster than C, it falls straight out of the Lorentz transform equs... this is why nothing can moving faster than the speed of light.
BullShitThat 3 months ago
@BullShitThat That sounds good in theory however as most engineers know theorys/equations get close most of the time, reality is a little different. I personally lean more toward gravity having "instant" propogation. Are you saying the LHC guys have misred their data?
crashlight1 3 months ago
@crashlight1 1st off there seems to be a bit of confusion going on here,...physicist have known for decades now, that gravity is not propagate instantaneously. (If it did, things like gravitational wave detectors would be useless) This includes the physicist at LHC, there's NO data that has ever shown other wise. You either must have miss read an article, or misinterpreted what they were saying, If this is not the case please provide the credible source, from where you're getting this info.
BullShitThat 3 months ago
@BullShitThat Gravity propogation at speed of light is still a THEORY. It even says so in the Wikipedia article, and I quote: "Gravitational radiation is THOUGHT to travel through the Universe at the speed of light..." and " Various gravitational wave detectors exist. However, they remain unsuccessful in detecting such phenomena." Maybe if a detector can't detect it it's not there and so far gravity wave detectors have been useless.
crashlight1 3 months ago
@crashlight1 PART1. Just because something is a theory does not take away from its validity, in fact 90% of modern physics can still be consider a theory. Gravity propagating at the speed of light in particular, is a VERY GOOD theory; one that fits perfectly with our well founded understanding of physics that has been proven right, time and time again, through rigorous tests and experiments. ...
BullShitThat 3 months ago
@crashlight1 PART2. …If this were not the case we would not only have to rethink our view of gravity, we would also have to and disregard some of our best theories today, throw out 1000s of text books, rewrite the standard model, explain why it was the case then but not the case now, and the list just goes on.
I far more inclined to believe in a theory that fits perfectly with all that we’ve ever known as humans, than a theory that is completely the opposite of this case.
BullShitThat 3 months ago
@BullShitThat Well at least we're agreed it's still a theory. I'd be happy to toss all text books for the truth wouldn't you? Hopefully our research will someday end in an answer. Of course if we all agreed on everything how boring that world would be. If you're right I'll buy you a beer and you can take your time to enjoy the gravity of it.
