Forward Time Travel--not a problem. Backward Time Travel I believe is impossible based on thermodynamics, among other things. Having said this, I'm fleshing out the plot for a time travel story.

ok , i did say , i would think. i read all you said , and you know more than me. i can learn from it, thats why i joined . thanks for the info......metalmind
specfiction,<br /><br />Time travel in any form is one of my favorite reads all my life. I cannot really say why, but it has always been my interest. What did you think of "Frequency"? I did have some concerns with the star having two sets of memories once he first saved his father from the fire, and some other things, but still enjoyed it. <br /><br />Have fun with your research on your book.
Frequency was a great movie, I enjoyed it very much. I also liked the Butterfly Effect, although it delt with a very disturbing subject and was not science fiction.
Does that mean, even if we go to future we cannot return back ever?<br /> <div class="Discussion_UserSignature"> <strong><font size="2"><p align="center"><br /><img id="a9529085-d63d-481e-9277-832ea5d58917" src="http://sitelife.space.com/ver1.0/Content/images/store/9/2/a9529085-d63d-481e-9277-832ea5d58917.Large.gif" alt="blog post photo" /><br /><font color="#339966">Oops! this is my alien friend.</font></p><p align="center"><font color="#ff6600">╬→Ť╠╣є ’ M€ ’<br />╬→ Ðôŵņ2Ëãřŧĥ ๑<br />╬→ ЙДm€ :Varsha<br /></font></p></font></strong> </div>
I believe that it could be possible to travel forward in time. However, going back in time is impossible. Knowing that, I don't think I would want to go to the future.
This is all from what I heard, read and saw on various science sources. There was the test where two atomic clocks used. One on a plane and the other left on the ground. The plane traveled at high speeds and was found that the time didn't match anymore. I look at time like this. Time is the moment with energy. Give it more energy and time will run differently. That also works with taking it away. Traveling at high speeds lets you into the future. Pending on the speed is how far you go. What if someone found a way to stop completely. Down beyond the subatomic level of all the atoms. In my theory time would stop possibly go back pending on veiws. The only problem is if you managed to stop everything there is no way without being destroyed to start it all back up. If a way was found the past would have to know about it because the only way I can see it working is if an outside force is what starts it up of which time the outside force must know about it. I have done no tests and have not heard of any such tests, but that is just my theory on the possiblity.
<i><font color="yellow">If a way was found the past would have to know </font>/i><br /><br /> Our past would never be changed, even if you found a way to travel back in time. The reason for this is because the moment you change the past, a similar but different parallel future is created. With that in mind, you could never return to the future you left. It is with this thought that it can be said you never actually travel to the past, since the past you travel to is the future of a different past.</i> <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>
Enigma, while what you describe, or "The Many Worlds Theory," has no evidence for or against it, I wouldn't talk about it as if it were factual.

</font></p><p> </p><p><font color="#339966"> The following goes without saying:</font> </p> </div>You have to reflect upon what time is. There is imaginary time and real time. Imaginary time runs both ways and exists orthoganally to real time. Imaginary time is the time used in physics though it is common not to consider it as such unless dealing with quantum mechanics. Real time is the time we know and hate and is tangled up with entropy. Entropy is essentially a cosmic history book in that every every ingram of information has a history. All modalities for time travel use the escapes by which imaginary time becomes dominant and information (people) can be reinserted into space-time at a different locale. However, one has to keep in mind that all histories are quantum. If you emerge into a previous era then you will have a coherent history. You will remember living in that era and those around you will consider that you have always been there. If you had modified DNA those modifications will have naturally occured in the history of your organism. If you emerge in an earlier time where you are alive you will be a relative of yourself, a twin. You will not remember living in the previous time since your brain will be coopted by local history. <br /><br />If you kill your grandfather, he will be gone from future history and if they catch you, so will you. But if they don't catch you, you will live out your days in your new time believing that you had been there all along, which you will have been.<br /><br />If you go back to a time before humans, then all of a sudden humans will have evolved more quickly and you will have a complete history and set of new friends.<br /><br />So, when you look around and see the population swelling, know that the babies aren't really booming. There are just a bunch of immigrants coming back from the 25th century looking for a quieter life.<br />
Hey, can we include black holes in ths disscussion...which according to some theories can enable time travel...have any idea? <div class="Discussion_UserSignature"> <strong><font size="2"><p align="center"><br /><img id="a9529085-d63d-481e-9277-832ea5d58917" src="http://sitelife.space.com/ver1.0/Content/images/store/9/2/a9529085-d63d-481e-9277-832ea5d58917.Large.gif" alt="blog post photo" /><br /><font color="#339966">Oops! this is my alien friend.</font></p><p align="center"><font color="#ff6600">╬→Ť╠╣є ’ M€ ’<br />╬→ Ðôŵņ2Ëãřŧĥ ๑<br />╬→ ЙДm€ :Varsha<br /></font></p></font></strong> </div>
The ancient Greece and Medive Alchemyist believe it was possible to turn lead into gold. Then came the Chemist who in the 1700's said it was inpossible to turn lead into gold. Then came the modern nuclear chemist where it is possible to turn lead into gold but it will cost more money than the gold is worth now. The do turn mercury into radioactive gold for medical use at great expense for the government. I believe travel is possible but there is than Time Police to Police Time to stop change.

Time travel is possible, but only in one direction. <div class="Discussion_UserSignature"> </div>
The answer regarding time travel varies, depending on whether we're talking about real life or fiction (the thing to which this particular forum ostensibly is devoted).<br /><br />In <i>real life</i>, the only truly honest answer is that nobody knows -- although the fact that none of us has ever knowingly encountered a time traveler gives one a good reason to be skeptical. Folks blabber on about wormholes and black holes and this and that -- but are mostly just making stuff up as they go.<br /><br />If I could figure out how to walk through a rotating black hole and emerge intact from the other side, I suspect that time travel (if it is indeed a side effect of walking intact through a black hole) would rank among my lesser abilities. Hell, if I could go frisking through a black hole, I'd need to pinch myself and check whether somebody had died and appointed me God for a day. For that is pretty much what it would take in order to venture in past an event horizon and then emerge unscathed.<br /><br />The only well-established model for time travel involves flying a spaceship at a sizable percentage of light speed. As others have suggested, this would give one the ability effectively to move forward through time relative to the folks one leaves behind. I agree with the poster who said she wouldn't want to make the trip. But it might be an interesting way to transmit to the future an uncrewed time capsule or other information that might otherwise become lost.<br /><br />Now, if we're really talking about <i>fiction</i>, then all bets are off. In this realm, the avenues for time travel are limited only by the scope of our collective imagination.<br /><br />See you tomorrow... <div class="Discussion_UserSignature"> <font color="#0000ff"><strong>Just tell the truth and let the chips fall...</strong></font> </div>

We can travel to the future, fast speed near C will cause huge time dilation so that time tick slowly. To freeze the time and travel any occupied any point in the universe instantly, you need to travel at C which is impossible. To turn back time, you need FTL, definetely impossible. Note, time dilation only applied to the traveller. <div class="Discussion_UserSignature"> </div>
hi,i m new user.cherry i m satisfied with ur view.i also confuse that if ever we would travel to our past we will make history changeable.But i think u r unaware of the concept of parallel universes.
hi,i m new user. i favour ur point since if ever we travelled to past then we will actually travelled parallel universe.But do parallel universe actually exists .
There is an article out today quoting various scientists saying time travel is not possible [based on what we know - Ed.]. It does discuss that it is possible to travel to the "future" by traveling near the speed of light. Since we have anti-matter, anti-protons, anti-quarks, etc, doesn't it seem possible that there is an anti-speed of light that would allow time to reverse?
Next year there will be an article saying time travel is possibe. Depends on what scientist you talk to. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life. Those who make it happen, those who watch it happen...and those who do not know what happened.</em></p> </div>
I personally think time travel is possible, though right now the complexed technologies to achieve it are simply not around yet. For our scientists and professors to say something like this "Time Travel Isn't Possible" is a bit like saying the building of concorde was Impossible, or Man landing on the moon. Though lol I don't profess that I know about time travel either, I feel to say something like that to fast, is a sure sign of being a defeatest, something alas i am not. Wish i was a scientist lol.<br /><br />Einstein i believe once said the pure sign of a genius is having the ability to solve a set problem from another perspective or angle. The present idea's with time travel may prove costly and technologically demanding, though have they looked at all the angles, or is there a back door theory that has yet to be investigated, that could prove to be the holy grail of time travel knowledge.<br /><br />For a technological civilization as our own to admit time travel is impossible is stupid, and professionally careless, what if a scientist proved them all wrong lol, and achieved a working example of it. I can see then they would be scratching their heads and burning their thesis's on sacrificial alters lol.... Plus what would such a claim if proved wrong do to the reputation of these very respected scientist be as a result, being wrong could prove quite damaging to them i think. So such a claim is stupid and careless. If they had said, according to current research, mathematical and technological time travel theory seems impossible, then that would have said their view better... leaving them open to the possiblity that someone if they had achieved it, they in turn wouldn't discredit our scientists reputation... talking about putting ones preferbial head on the chopping block lol, they did with such a comment. <br /><br />It's obvious now such a claim has been made, that loads of scientists will want to prove these guys wrong, and work undercover with
