Will Time Travel Ever Be Possible?

Answer 1

Going forward in time vast spans is theoretically possible now, but beyond out current engineering. The time dilation effect means that if you can accelerate to near light speed, and then stay there for a while (which depends on how near light speed you can get), you will have to opportunity to slow down into the far future. The closer to light speed you can get, the shorter the time you will have to stay at that velocity. Of course, no one currently has any idea how to build a ship that might accomplish that, but that's just engineering.

Now, your going back in time is going to be ruled out by quantum mechanics. If this weren't so, then you could violate the uncertainty principle. You could conduct an experiment find the position of an electron (say) with very high accuracy. Writing that down on a slip of paper, and sending it back to yourself. You could then decide to focus on the velocity of the electron instead and find it to a very high accuracy. It is conceivable that you could determine both measurements this way to be more accurate that is permitted by the uncertainty principle. Not, possible, of course; so, no going back.

Answer 2

I answered this same question from someone else earlier - however I had realized shortly after that.., that there is a possible means for time travel, just not at this time.

At the current thought of time and relativity - science would have to develop something you hear about on science fiction movies, called Inertia Dampeners, and at least an aircraft or space craft capable of attaining light speed or faster than light.

Once those two elements are brought together - a man could survive light speed or sub light speeds with no hassle whatsoever. However - it would only be FORWARD in time, not backward in time.

The faster one goes - time remains the same, though the world around him would be getting slower and slower.

To travel backward in time - a mechanism would have to be discovered that slows present time to a stand still for an undetermined amount of time (for the time traveler) while time in the real world would speed up. At some point the time traveler's present will have to catch up with the past. If the forward travel in time is true - then the reverse (as illustrated) is equally true.

Hence foreword time travel would be more likely to occur far before past time travel will.

LASTLY - I doubt very much that mankind will survive long enough to solve either one of these dilemmas to break the time barrier to the past or future. We have wars, diseases, the threat of nuclear war being greater than it ever has, global warming, strange unpredictable disastrous weather due to global warming not to mention earthquakes and destined tsunamis.

The odds are against mankind surviving even another 100 years. If by some miracle mankind survives it, technology would be set back by almost a hundred years. Or so thats my prediction. So short of the Second Coming - I see no hope for mankind's survival and his extinction is assured.

Answer 3

If we ever acquire the ability I will go on a mission back to right before you asked this question and give you the answer so you don't have to ask here. Of course in that case you would have never asked the question here and I would have had no reason to come back to give you an answer. But then I would have never came back, so you still had the question so now I do come back to answer the question you asked, but then that would answer your question so you don't ask it here and I have no reason to come back and answer it. See the mess time travel creates? It will probably never be possible in the way they did in in Back to the Future, but theoretically you could travel close to the speed of light for a while and come back to earth and lots of time, like thousands of years will have passed here while you experienced only a couple years. But you couldn't go back to the past to all the time you missed on earth.

Answer 4

Probably. From what little I know of Einstein's theories on time dilation, it's just a matter of being able to travel fast enough to affect time. I doubt that it will ever be as easy as jumping in a phone booth like Bill and Ted, but strictly speaking, it could be possible.

Answer 5

What! - I just got back - what year is this?

Sorry, I couldn't resist the sarcasm. NO - time travels in one dimension - forward - that's it.

To go forward in time is impossible too, unless there is some sort of cosmic phenomenon in the Universe that we have not enountered or discovered yet enables one to transverse this time dimension and slip into another one ahead of it (and man will never live long enough for this to happen by the way).

Answer 6

If it will be possible in the future, why are we not being visited by time travelers from the future?

Answer 7

i do believe time travel will be possible in the far future.... but im also sure a law will pass to stop the use of time travel. dam paradox is such a headach....

Answer 8

In the near future, scientists may be able to transport matter back and forth through time, so yes.

Answer 9

yes but in a body that does not obey the Rules of gravity and the lphysical laws.

Answer 10

No coz , think about it, if it ever were, wouldn't they have been here by now to tell us.
