special w/ Stephen hawking once...I think it was called "through the wormhole" or something. going back in time isn't impossible, while going forward in time, theoretically is. You need to travel really fast, and If you travel fast enough, time slows down, to the the point that if you spend 10 days (in slowed time) traveling at that speed, when you stopped, it would be 10 or 20 years in the future.
I n a Sense - you can travel faster than the speed of light and sound - go to mars and the moon -- and who really knows All the years the government kept going up / and now even Justin Blieber went up or is going up
So many ordinary things we have available today were deemed impossible in the past, starting with the iPhone in your hand. I wish someone invented a camera to record my dreams, so I could watch them in detail...
The dimension we live in ( earth, universe, and everything we can see, touch , smell and feel) is with purpose. Afshin's laws state; 1. Where there is no purpose to something, that something seizes to exist. 2. The purpose is every moment, every moment is a test 3. You can only take the next test, it is not possible to redo a test.
Its possible and has already happened. On the Apollo missions to the moon, high speeds like 20,000kph were reached. Time slowed down on the Apollo craft compared to Earth time. This was proven by having two synchronized quartz crystal clocks, the one on Earth was became about 2 seconds advanced on the one on Apollo. In other words the Astronauts were coming back into their future by 2 seconds. If we could travel faster for longer, people could age one year on the spacecraft but come back and find 10 years had passed on Earth. I'm astonished by the 100% fail of all previous answers, is this just a kids guessing forum ?
yes time travel is possible only if the time goes back in zero and a big black hole is seen and you go in it within 1 second with the full pressure of the atmosphere but i also exactly don't know i am just 13 but in our school some engineer bhaiya come and said these thing about time travel and i a roll play my friend also said same thing and she found this on net
no it is impossible , even it is not a happy wish to return by your time back ,,because you will return back alone through this funny machine and when you return to your real time ,,you will find all of your world changed again ,so it is a joke for films just !
Our (Human) perception of time is linear, going from past to future. There are those that say that this is not an accurate representation of time, and that there might be other realities. Not sure that we could ever travel "back" in our timeline, but that doesn't mean that there might be other ways to "travel."

Time travel forward is possible by increasing your velocity. Imagine a parabola where the closer to the speed of light you are traveling, the faster you are also traveling through time relative to somebody outside of your vessel travelling at a much slower speed... This is confirmed because our GPS satellites needed a correction factor to speed up the on-board atomic clocks so they would sync with those on the surface. It was observed that the atomic clocks on our satellites were clocking more slowly than those still on the surface due to the higher velocity of the orbiting satellites.
Time travel backwards, however is not possible above a quantum scale. Only useful for sub-atomic particles...
There is a compact region of spacetime whose boundary is topologically trivial but whose interior is not simply connected. Formalizing this idea leads to definitions such as the following, taken from Matt Visser's Lorentzian Wormholes:
If a Lorentzian spacetime contains a compact region ?, and if the topology of ? is of the form ? ~ R x ?, where ? is a three-manifold of nontrivial topology, whose boundary has topology of the form d? ~ S², and if furthermore the hypersurfaces ? are all spacelike, then the region ? contains a quasipermanent intra-universe wormhole. Characterizing inter-universe wormholes is more difficult. For example, one can imagine a 'baby' universe connected to its 'parent' by a narrow 'umbilicus'. One might like to regard the umbilicus as the throat of a wormhole, but the spacetime is simply connected.
great question - of course no one's actually done it - like they do in the movies...but you can (with your imagination) travel inter-dimensionally: return to an event or situation, or project yourself to another place and time, where important information and energy can be transferred, or conveyed meaningfully
we have already recreated the higgs boson (god particle) and the teleportation of simply cells so the idea is realistic, although it would probably never be released to the public seeing how we cant even control our brute technologies (such as guns)
Time travel may be possible....but not at present situation .....This is because,according to the general theory of relativity,for a person travelling with speed of light has clock running slower than the normal.This shows that one must exceed the speed of light and which is practically impossible.If one must have unfortunately fall into a black hole,he must have the escape velocity greater than the light's speed.i.e.he is falling into it with the speed of light.Thus it makes that in a black hole,your time will be very slow than usual.So for a person outside a black hole,it would appear that the person in black hole is at the same point for a long time.Hopes are still going on for time travel in this direction of thought.But as many are thinking that time travel for means of knowing the future or past is just a myth.
i think we can if we reduce our mass and increase our speed.but about worm holes i don't think they wrong .so if we hit a small ball with force of light it can begone to future or past.about one thing their is an experiment i really know :rays of light was captured in a box thing and with tiny camera.after a few seconds it just diaper .where did they go?we they see the record the light were in the box before they ready to do this .so yes
for example: you go back in time to kill your own mother, before she gave birth to you, making it so that you will never be born and will never travel back in time... but who the hell killed your mother, then?
It is and it isnt. It depends on your definition of time-travel. We can slow down our personal time with high speed travel so it seems like we are travelling into the future so if that's what you call time-travel then, yes, its possible. But if your definition leans toward actually visiting the past then no, it isnt possible. And we should not try to! Can you imagine what the world would be like if someone could change the past? What if someone caused Hitler to win? Or Napoleon? Or any major world changing event's outcome becomes different? The world we live in could become a much different place.....and we wouldnt even know it.
At the moment, it appears it is not. Of course most people would've said the same thing about space travel a hundred years ago. But... since it's time travel we're talking about, if it EVER becomes possible, even if it takes a million years or more for such technology to develop, then it is possible right now... and it always has been.
Well, hypothetically speaking, using hypothetical theories and hypothetical technology far more advanced and nearly infinitely beyond human capacity to produce or master, yes; time travel is possible. But in reality, no; time travel is not possible.
The usual exceptions are, of course, living (I've aged about 5 minutes since beginning to type and edit this) and approaching fast-as-light travel (where time and you begin to do weird things without the other noticing). But these aren't what you're thinking of.
I know it's not (at least for me) because if it was I would have traveled back in time and warned myself not to get involved with my ex. Since that did not happen, and my life is in a shambles now, I can only conclude I will never time travel.
well if u r technical than yes go to the border of a place with a different time at 11 pm go across the border ti will be 12 am the next day than go back over it and its 11 pm agian so yes its possible

Theoretically time travel is possible though the act of going back in time to change something is very unlikely due to the fact once a change has been made you would have already lived through the moment and since this would be the case you wouldn't have a need to go back in the first place. Now the only way I can going to be a reality is when people have no subconscious goal of dong so thus eliminating the fact that the want to change something ruining the space-time continuum. Another way around this might be simply creating another universe/pocket dimension which would co-exist along this universe. Though for me the most plausible idea would be to travel into the future thus not affecting the past or present so long as the person is merely an observer. Please correct me if I am wrong.Though the adverse effects are in truth only theoretical and likely never to be proven unless mankind will be able to master the art of moving at the speed of light which according to some law of physics (I'm not sure I forgot) is impossible for a object of physical matter eg. a Human someone correct me if i'm wrong.... Plus is it unnatural for a 14 year olds to know this I need outside opinions?

Yes it is! For example walking from your home to your parents house will take about 30 minutes, but if you go to your parents house by your car, lets say, it would take about 15 minutes! And That is time travel, which we use it in our daily life! Time is equal to distance!
No. The quantum mechanic tells us: When a system is in a state Y and Y = 50%a + 50%b and a, b are eigenstates and we measure the system, we then get a OR b. So after a measurement the system is in his eigenstate. So information is lost and can't be restored. So we can't go back in time.
On the other hand. When we don't know the starting conditions, measure a system and we get a eigenstate c, we can't say (without knowing the circumstances): "Hey. Originally they System was in state Y = 10%a + 30%b + 60%c"
So no. Time travel under these circumstances is not possible.
thankfully, time travel isn't possible. imagine how many things could be effected if EVERYONE went and changed the past. Kids you currently have that you love could suddenly not exist, you could end up not winning the lottery, etc.
Theoretically. However, if you were to go back in time and change the past, nothing would happen in your time. Also you would need a spaceship capable of surviving the force of a black hole (and a human, nonetheless). So you'll probably never time travel. Sorry.
Yes, time travel is real. Since I was a child, I've had numerous experiences where, as I slept, I dreamed of certain events, only to see those same events unfold before me in my wakened state. I would have loved to be able to tell everyone what was going to happen, but I was unable to, because I never knew if it would be repeated. This was in large part because those were not the only kind of dreams I had. I was never able to change anything either; for the moment I came to the realization that I had experienced it in my dream, all my thoughts became the same thoughts that were in my dream and I was dumbfounded. I couldn't say or think anything differently.
