About Time Travelling...

...Travelling backwards in time will always remain as a part of Science Fiction, but then again, Travelling forwards is - and probably will be a possibility in the near future - by either cryocenic freezing, or a spaceship which is able to generate enough energy to create a so called worm-hole in space. The key is in Time being relative.



However, let us form a discussion about Time travelling, and the possibilities of it there of.

This is how I see it. Time is considered its own dimension, but it isn't spacial. We can't move around in it. But suppose we could? I think there is a way to move around in the time dimension as if it were a normal dimension. We could then move forwards, backwards and even sideways in time. Of course, you wouldn't see yourself moving through it, I don't think you would be able to look in a direction of time and see the events that happened there.

There is no reason why we should never travel forwards in time.

 

Look at time as d4.
We travel at a 'constant' speed in one direction along it.
If we can manipulate it to allow the speed of travel in this direction to be varied, what would stop us from manipulating it to allow us to go backwards?
There are obvious causality considerations which must be accounted for, but the actuality of it should be no more difficu than generating accelerated forwards motion along it's axis.

My thoughts.

 

Esp, if we would truly find a way to travel backwards in time, it would debunk all religions. Secondly, we could only watch the events - and not manipulate them; for our actions might change future greatly... and as what has happened, has indeed already happened, we can not change it - if we are not talking about another dimension.



If there are billions of parallel universes stacked upon each other, we could take it as a theory that time-travelling COULD be possible... but if we have only this universe - only these dimensions we are aware of, then, no way.

 

This may be a complex theory, but my idea of time travel states that for every frame of time (picosecond I guess) another dimension is created, and we are moving through one at every frame. So, if we wanted to go back in time we would have to open a portal to a dimension to our dimensions side, and we could do whatever we wanted there because that dimension would be wholly different from our own, it would be separate. The same thing goes for traveling forward.

 

Time travel is impossible.,Whether to the future or the past. This is because:

1.The past is over. Theoretically everything you know, knew, or ever will know is the past
2. The future is like a huge program. Everything happens on what you did in the past and nothing is a set control. If you do something, one of infinite reactions will happen.


Time is not an element. Nor a dimension. I even regret calling it an idea, because "Time" or the "Future" depends on the present which is the past. And technically the future is the past. Time is a paradox for fools and dreamers

 

Thirty Seven, Time Travelling forward is possible - if you find a way to travel multiple times faster than light. Time will flow differently to you - and one day to you might be 80 years to the people living on earth. So, IMO, it is a possibility.

 

I have yet to be convinced that the whole time-dilation thing works as many people claim (without proof, I might add). Either way, I doubt we will know the anser here until we can actually perform the task (fly a ship that fast).

 

If you fly a ship that fast you'd only freeze time the moment you reached light speed or close to it while everyone else moved forward. From their point of view you wouldn't have moved, however from yours once you stopped moving at lightspeed everything around you would've skipped, the friends on the radio would be done with conversations that had begun seconds before, that sort of thing. I think I'm correct but I'm not sure.

All in all, you pitch the universe forward in time while you remain in the same place.

 

I'm still not convinced. Even if you can achieve traveling faster than light, it wont take you to the future, the future hasnt hapened yet.

 

I think that whole idea about going faster than light and heading into the future faster than you should is basically a misinterpretation of the facts. If you go faster than light away from Earth, you will overtake/pass through the light travelling away from Earth so that you could, if you looked back toward Earth, see its state in about 1950 or whatever. This does not in any way indicate time travel. All it means is that you are travelling faster than a signal/emission. As you travel back toward Earth, the relative frequency of the emissions/signals will increase due to you heading into them. Again, this does not indicate time travel.

 

I've heard that as well, good point

 

i think the theory of time travel is unrealistic in the way we all look at it. Time is not relative as a whole butrelative to each person. time is man made definition. you cant graph time. if you try to it makes no sence. it like trying to see it like this
(numbers = some measurement of time)
1(now)------2(fut.)------3(fut.)------4(fut.)------5(fut.)------6(fut.)

1(past)------2(now)------3(fut.)------4(fut.)------5(fut.)------6(fut.)

1(past)------2(past)------3(now)------4(fut.)------5(fut.)------6(fut.)

you cant define a point in time as being present past or future. its like trying to say that one point is more "here" than another point is "here".

i think if theres any way to time travel its through alternate dimensions

 

Good points. Perhaps future and past as dimensions of time are unexistant, and the only existing form of time is present. With every second, we redefine ourselves. We will always be in the present.



Then again, what I displayed as theory is rather science fiction than based upon any facts. I wasn't speaking about travelling into the future, however - I was just referring it to the relativity of time - if it exists.

 

Can a two dimensional being (though none exist as we know it) move through the third dimension?
I think if we figured this out, it would answer our question on time travel. That is, whether it's possible or not.

 

Time Trave is Possible

Time travel is possible and has occured and is always occuring. Russian Cosmonaut Sergei Adeyev (The one who spent 2 years in MIR) is the first major time travelor. Being on MIR going at the fantastic speed he travelled 1/50 of a second into the future. The faster an object is moving, the faster into the future it is going. This has been going on all along. A clock in motion ticks slower than a clock than a stationary clock; a moving clock travels into the future relative to the clock at rest. We only now have tools accurate enough to detect it. This is all proven, look it up if you do not believe me.

Practically (Now), the closer you get to the speed of light the farther into the future you go. If you go the speed of light, theoretically time stops. Then theoretically if you surpass the speed of light you go into the past.

As of now we only know travel into the future is possible, in time we may know more. I hope i have been of help

 

Isn't it that when you travel faster time moves slower?

 

Pollux - try this...
