Do you belive time travel is possible?

Question

I have recently belived it is possible to go forward,and I know the explination but i dont think it could ever be possible to go back.

Answer 1

only if the flux capacitor is correctly installed in a delorean

Answer 2

I do not believe that we truly can understand space and all that it has to offer in that it is infinite to start off with. Do I think time travel is possible in some other space, possibly based on the fact that the possibilities would therefore be infinite as well. Time travel could explain some annomolies and how some people seem to have knowledge above others like nostradamus, einstein, da vinci and such. They could have possibly had a glimpse then had to decipher what they saw thus thier knowledge would be explained easily. It would also explain a deja vu, but I think time travel is more of a hope than an actual reality at this point.

Answer 3

I) Introduction

Before 1905 there wasn't much to say about time. In the 17th century Newton defined time as something that continues, no matter what, without any link with reality and according to its own nature. Everybody believed that time had its influence on the environment, but if you believed that the environment had its influence on time, you really had to be mad! That changed in 1905 with Einstein's special relativity theory, in which he showed that time can be influenced. But this doesn't mean time can be changed in such a way that you can travel to the future or the past. That's what it's all about on this pages: Is it possible to travel through time, and if possible, under which circumstances?
It will become very clear that the speed of light has got a major influence on the possibility of time travelling. An object should move faster than light speed to travel through time. Therefore we use the tunnel effect, an effect in the quantum mechanics. That means that a ray of light or a bundle of electrons that is sent through a certain barrier arrives sooner at the other side of the barrier than if there wasn't a barrier.
If time travelling is possible according to the relativity theory, there will be a lot of other problems. I'm not talking about the technical problems, 'cause that's not what this is about, but I mean the paradoxes. For these problems there is no such thing as a logical explanation, no matter how long you'll search.


II) Relativity

There are 2 sorts of physics: Newton's physics and Einstein's physics. When you use formulas from Newton and formulas from Einstein's physics to calculate a certain physical value, you'll become not the same value. In 'normal' situations these differences are extremely small. But in 'extreme' situations these differences will become very big. For example: someone who's in a train that moves with an incredible high speed (like 10 000 km/second) and who measures the distance between the sleepers of the train, will measure a smaller distance than someone who stands still beside the railway. According to the physics of Newton and our intuition we'd say the distance would remain the same. In 'normal' situations that's correct: measuring in a train that moves at hundreds, thousands or even ten thousands kilometers/hour would make the difference in distance immeasurably small. Newton's laws would certainly do in these situations. But when the speed of the train approaches the speed of light, the difference will become noticeable ('extreme' situations), and we would need Einstein's physics. According to the latest experiments, Einstein's formulas seem to be the right ones.
Einstein's special theory of relativity was finished in 1905. It's based on the constant speed of light and the fact that speed isn't absolute; when a helicopter lifts off you can also assume it's the chopper that stands still and the earth that moves. This theory describes the relation between observation of a certain phenomenon by observers that move with a constant speed related to each other.
The general theory of relativity was finished in 1912, but Einstein couldn't interpret his mathematical reasoning physically. He redeveloped the theory, not only based on mathematics but also on physics, and he ended up with the same result as 3 years earlier. Then he published it. This theory describes on one hand the relation between the observations of the observers that move with an accelerating speed related to each other. On the other hand it's about the influence of gravity on observations and the relation between observations that are done from places where gravity differs. Because a constant speed can be looked at as a speed with acceleration 0, the general theory of gravity includes the special one.

Answer 4

i'm don't know about time travel forward in time, but i believe stephen hawkings has mentioned somewhere before that he believes time travel backwards in time is not possible..

if not we'd be surrounded by people who've come back from the future. besides, if you can go backwards and change things in history, grave consequences might ensue, such as you going back and somehow ending up killing your own grandmother, which effectively erases your existence. this would mean that there wouldn't have been a you to travel back in time in the first place, creating a paradox.

however, there are theories of infinite parallel universes that make it more plausible for time travel backward, in which case you travel back to another parallel universe, so that whatever you do there would not affect your original universe.

Answer 5

i dont think it is possible only because wouldnt people from the future be here right now?

but something cool to think of that i learnt in astronomy. light can only travel a certain amount of speed so when we look at something like andromeda which is 2.5 billion or million lightyears away (or something like that) we are really looking 2.5 billion or million years into the past. in fact, there is a possibility that someplanets and stars dont even exist anymore but we still see them.

pretty cool eh?

Answer 6

No, I do not believe that time travel either backwards or forwards is possible. It does, however, make an interesting story when referred to as a working development.

Answer 7

personaly, I dont think it's possible, because then it become like a loop if someone were to go back once and then go to the original time. To go forward wouldnt be too posible, either, because if we did have the tecnology in the future, what would stop someone from going further in time to the point where they could go back, and that causes the whole loop thingy.

Answer 8

I have traveled into the future in some of my dreams. By future I mean, like a day or two into the future. Seriously.

Answer 9

Not only possible but practical going into the future, as I have detailed many many times

Answer 10

time travel seem svery possible, they have already mapped out ways to create warp speed and also teleportation with large magnets (all theories of course but plausible), stephen hawkings has described ways of doing it, but i also agree that forward is possible and backwards never.

Answer 11

Of course. I travel into the future continuously!
