travel in time is just a myth?

[subversion]

The reason why there are so many hypothesis made about backwards time travell is because it fascinates us more, and even though that is to be decided by psicologists, I believe we are fascinated by the past because we have lived it or we are documented on it, but as humans, we are afraid of the unknown, and the future is the unknown. Most of the theories about backwards time travell are in fact science-fiction, and the few which are scientific, are not realistic for the advance of humanity now, but for a few centuries time. Whereas forward time travell not only has been hypothesized, but proven. In fact, we are proving it now, me by posting this post at this moment, and you by reading it at the moment you read it. Yesterday you were in yesterday, today you are in today, and tomorrow you will be in tomorrow. This proves that you have had time travell and that you will have it. The thing is that we are always travelling at the same speed, or nearly the same speed. But ofr example, when austronauts come from a space mission, their watches are retarded by seconds, because they went at very high speeds, and thus their time was slower tha ours (but they never experienced the difference, for the one that is at fast speed, he is moving normally).

Good synopsis, I would have to agree

what you are mentioning over here is the theory of special relativity at the section of time dilation. traveling at the speed of time means the time for you will stop. eventhougth IF you manage to overcome that speed many grate sientist agree that tgere is chance of traveling backwards.so we have a diagram like that:> u<300000km/s->just yime dilation
u=300000km/s->no time
u>300000km/s->tie traveling backwards
u>>>300000km/s->time traveling backward faster
well were is time traveling forward faster??????

You understood nothing of my post or of special relativity. If we are movng at 1km/s and accelerate to 295,000km/s we will be moving faster travelling forward in time. I don't knwo what youa re trying to proof, but it's wrong if you want to base it on the assumption that backwards time travell is more plausible (or possible) than forwards time travell. There is a list of reasons to believe why forward time travell is possible:
1. Entropy increases in the direction we call 'forward'.
2. Systems get more complex with the move in 'forward'.
3. We are not static, time avances, we are today and not yesterday, humans govenr the world not the dinasours... all these mean that time is moving forward.
4. The many many experiments done to proof that as you increase your speed towards the speed of light, time moves slower and slower, this has been proven with the help of particle accelerators.

And there is a list of reasons to believe that backwards tim travell is not possible:
1. Entropy does not decrease.
2. To achieve the speed o fligh,t we must have zero mass, but as matter is something that has mass and occupies space, we as matter bodies cannot acheive the speed of light. Therefore not only it is impossible to go faster than the speed of light, but also at the speed of lgiht.
3. The energy needed to increase speed grows ultra-exponentially when you get near the speed of light, and is finally impossible (not evne all the energy of the universe would accelerate something with mass at that speed).
4. All the paradoxes which have been stated about backwards time travell.

There are many other notes, but the point is that backward time travell, although it is a beautifull idea, it is, according to proper physics, not possible. And even if it is discovered that it is possible, humanity would never be enough advanced as to try it. Anyway, if it is theoretically possible, still, it won't be more possible than forward time travell, for this is the one which is the 'natural flow', the 'universal motion'... All is forward in time.

I have a serious doubt biology actually depends on travel in time. We are travelling in time as a complete entity rather than as cells.

dear pagan3142
How can this be possible? if someone in the future manages to travel in time with out him prisoner in the moment every biological procedure in him will travel reverse. He will become younger and if he travel in a moment before his birth he will disappear.

Dipyankar;
The thing to remember here is that there are no paradoxes in nature. If an idea promotes a paradox, it is WRONG.

[pagan3142]

Consider this.
We remember Yesterday and can also remember the days and events before.
So Therefore in my frame of thought you not need mass to travel back in time.
Therfore any "Time machine" would be on a Level that has nothing to do with mass, but pure energy. Therfore the speed of light is probably the wrong place to look for any clue to time travel.
I believe that The answer to Time travel is simple. Just like a piece of string it has a beginning and an end (The Time period Journey).
From our 3 dimensionl view (to the closed minds, and those who have already made up thier minds) in this universe time travel is not possible. However If time is circular like the closed universe. then perhaps we will meet ourselves going the other way.
Just a Thought in my time. going travelling now.

Wrong again. A Paradox exists to challeng the closed minds

i think that time travel is possible. time is a part of the space-time curvature. so time can be bend this way. in our daily life we mive slower than the speed of the light and that makes us to move to the future as the time is continously running. so it must be possible that moving faster than the speed of the light can make us move to the future, as per the symmetery of the universe. so speed of the light may be that boundary beyond which moving would make us move to the past.

That may well be the case Manikgup,but are we ever going to be in a position to actually
test this theory?I think not!However there is another way,which has absolutely nothing
to do with light speed ,and that is astral travelling,you can visit the past and the future,
and also anywhere in the universe you care to go,so pack a bag,and set off!

What you have stated here is only partially true!But not absolutely true.
Partially true in the sense that the "relative universe" in which we "physically" live in
is paradox free,but totally false when one understands that "back off" this relative
universe,is the absolute alll-universe!And here Paradoxs exist by the SHED-LOAD,
The Primal Paradox states:That motion shall arise from motionlessness?

Michael and pagan3142;
The paradoxes you are referring to are due to the lack of knowledge we have of the physical reality of the universe. There are “ABSOLUTELY” no paradoxes in nature.

It is difficult for an empty mind to recognize a full one as anything but closed.

[mkirkpatrick]

We will have to agree to differ on this,I see that it is NOT lack of knowledge
that is the problem,but rather lack of acceptance!Two paradoxes that are very real
if you are able understand that is:One is that ALL motion arises from stillness?
And the other is that to fully understand life "you" must die!
