    Scientifically are there any kind of phenomena that modified would allow time travel? Or can we only hope for it to remain science fiction?

    Travelling to the future is already possible.

    To the past I think it's impossible.

    The closer you come to the speed of light, the slower your time will go.
    If for example you fly in a spaceship at 90% of the speed of light, your time will go like 50% slower. ( I don't know the exact numbers, you can check those by using the Lorentz factor ).
    So if you stay on the spaceship for 50 years, someone else not on the spaceship will see it as 100 years. ( Like I said I don't know the exact numbers. ).

    We can see the effect in the particle coliders.
    Let's say we have a particle that normally decays in 1 second.
    Now if they speed it up to close the speed of light. It decays after let's say 2 seconds.

    We travel into the future at the rate of one second per one second. I just traveled into the future 10 seconds typing this response.

    Lasciate tutta esperanza !

    Time is not a free coordinate at our hand.
    It is a statistical emergence of zillions of zillions of quantic reactions.
    As statistical as the temperature is.

    Even our macroscopic space is a such statistical emergence, but at least, as animals, we keep some mobility in macroscopic space, at the surface of our planet, at least.

    ok.... ok....... but i mean travelling into future which is to see ahead than the rate of 1 second. About what is going to happen next without going into the future itself.n now tell me of some SUCCESSFUL methods of travelling into future?????..........

    hello! you said that not by travelling in space will we go ahead in time but that way you yourself will not go ahead in time but instead your time will slow down whilst time on earth will go on steadily ...... this doesn't mean that you will travel in time instead due to speed your time will just SLOW down and by the way how can you remain moving in space by the time about 50 to 75 earth years pass by on earth ...........??????? that will require tremendous amount of fuel and of a non degenerating body.... you understand and now forget all that and think of some non-expensive and timesaving methods please ....... and not near to impossible and timesaving ways please.........

    If we will travel at 99.99 % of the speed of light, we can travel in the future, because our time will slow so much down that for example 1 year for you is 100 year on earth.

    So if u wait for 20 of your years, and then go back to earth, the earth has aged for 2000 years.

    So you traveled in to the future.
    The only problem is, that you can't go back in time to tell your friends you traveled in time.

    Edit:
    We don't need huge amounts of fuel, we also can use the slingshot effect from massive stars/planets.
    Or just orbitting around massive objects also slow down our time, so we can use that to.

    Btw. If you drive in your car, you travel more in time than someone standing still.
    This effect is just so small that we can't see it, but it happens.

    So if you ask me, is it possible to travel in the future? Yes.
    If you ask: Is it possible with some kind of cool machine that let us travel in time? No.

    It already exists.
    Remember the last time you fell over ?
    What can you see yourself doing in 5 years time ?

    Too many causality loops in physical time travel, would you get younger/older to fit the time you are at present during travel ? Or do you carry your present and future time with you ? If so you would be in your present in the past , something's got to give to much potential difference.

    Show the math where you break causality and implement time travel.

    Math, show it or retract.

    Time travel is science fiction. It's pseudoscience woo promoted by pompous celebrity "physicists" who've got a book to flog to gullible kids. I've said this before, but I'll say it again:

    Hold your hands up. See that gap between them? That's a space, and you can see itís there, even though you can't see the space itself. Now waggle those hands. That's motion, and you can see thatís there too. But can you see time? No. Can you see time flowing? No. Can you see any travelling through time? No. These phrases are just figures of speech. Thereís no scientific evidence for time flowing or time travel. Time travel is science fiction, and itís going to stay that way forever because travelling back in time is impossible. Itís impossible because we donít even travel forward in time.

    To understand this, think about a stasis box. Thatís science fiction too. Itís the ultimate refrigerator. No motion occurs inside the box, so when I put you inside one, electromagnetic phenomena donít propagate. So you canít see, you canít hear, and you canít even think. Hence when I open the door 5 years later, to you itís like I opened the door just as soon as I closed it. And get this: you ďtravelledĒ to the future by not moving at all. Instead everything else did. And that motion wasnít through time, and it wasnít through spacetime, it was through space. Yes, the stasis box is fighting fire with fire, but donít forget, we can freeze embryos now, so one day maybe weíll be able to freeze an adult. Then you could ďtravelĒ to the future by stepping into a freezer. But you arenít really travelling. You arenít moving. Everything else is.

    Travelling forward in time is just a figure of speech. It's like JC was saying, we don't actually "climb" to a higher temperature, and nor do we actually "travel" to a future time. Temperature is an average measure of motion on the atomic scale, time is a cumulative measure of motion. If you don't believe me open up the back of a mechanical clock. See any time flowing? Nope. All that's there, is things moving.

    Impressive, I see you do not adhere to the God of time as some special entity.

    If time travel was possible, wouldn't we have always had the ability to time travel?
    Wouldn't the people from the future go back in time, hand over the time machine to the primitives and educate them? Then time travel would have been in existence since our existence began. No?

    Your argument simply, once again, demonstrates complete lack of understanding of the issue at hand and of basic physics. Just what one expects from an internet crank. Holding your hands in front of your face is no substitute for understanding physics, particularly but not exclusively general relativity, which requires understanding the associated mathematics. You are completely ignorant of both, as you have demonstrated time and again. Crank.

    The question travel is best framed in terms of general relativity and the existence or non-existence of closed timelike curves (CTCs).. General relativity, by itself, is not sufficient to settle the issue, which has been made precise by Stephen Hawking with the chronology protection conjecture.

    Pretty much everyone expects that something like the chronology protection conjecture will be shown to be true. But it is not straightforward. Closed timelike curves do exist in some exotic solutions to the Einstein field equations. GŲdel's lambda dust space, the Tipler cylinder and Kerr black holes have CTCs.

    On the other hand Hawking showed that if the weak energy condition holds then there are no CTCs.

    Quantum fields, generally do not conform to the weak energy condition so chronology protection may well not hold at the quantum level. There are Feynman diagrams that include non-causal branches.

    There is good reason to demand a mathematical proof based on general relativity. Odd things really do happen. When black hole solutions were first found, many physicists, Einstein included, did not believe that physical black holes would exist. One learns in physics by pushing the limits of what is known and investigating situations that might be termed "exotic". Exotic is not necessarily impossible.

    Any proof of the chronology protection conjecture will have to include some conditions that constrain the admissible solutions to the Einstein field equations. The known exotic solutions with CTCs serve to demonstrate that fact. Again, general relativity alone is not enough. Staring at one's hands or one's navel, a favorite technique of Farsight, is also insufficient.

    In a sense the deep problem is that causality appears to not strictly hold at the quantum level, but it seems to apply in "normal" macroscopic situations. So, where is line between the quantum world and the macroscopic world where causality kicks in ? This is well worth understanding.

    Please ignore Farsight. He loves to pontificate, but understands nothing of the basics of physics. There is good reason why he refuses to produce hard physics, complete with mathematics, and fears the mathematics forum.

    Crank.

    time travel would be possible. and those who travel back in time might have good reasons for making it public?
