No one has the power to see or go to the future, unless we are all on a set path. Think of it as a never-ending book, that is continually being written. You can't go foward to a page that (isn't there/hasn't been written yet), right? So you have to wait for the 'author' (time) to write more pages.
If Einstein's theory is correct, and, while at the speed of light, you stop aging, wouldn't that be the only way to travel to the future? If you sped up time so that you stayed the same age while everyone else around you aged, you would, essentially, travel to the future. And, if we had a device to go back in time (which would be possible, taking into account that the past is already written, and time can rewrite it and thus change the rest of the book), then practical time travel would be a reality, correct?
Any thoughts or theories you have are welcome. No one flame anybody, please.(criticism is welcome, though)
This is just my theory. It is not the definite way to travel back and forward through time. It is just a thought.

The past is definitely out of reach. The only way to travel through time is by displacing a local time field (using, let say, a phone booth) in comparison to the rest. By displacing the time difference, the booth could move forward in time and back again to its starting point; it could not, however, move backwards in time, because that would create the inherent paradox of moving directly back into a time when it wasn't moving, thus never moving at all.
Einstein theorized we could not move forward because a physical body would have to be moving faster than the speed of light, which is impossible within Einsteinian physics. It is possible to see the future, with the understanding that there is an infinite number of timelines and that the one that one is viewing is only the one that will occur if no changes are made. Any changes that are made to affect what one has seen in the future will automatically lead to a seperate timeline.
Timelines are products of the fourth dimension, Time. For us dwellers of the third dimension, Time only effects us peripherally. For us it is linear and we cannot conceive of anyway to alter that. Within the fourth dimension, Time is not linear, it is constant. There is no cause and effect, nor any before and after, which means that travel to the future, past, and present are all one and the same.
I think traveling back in time is possible in limited extent.
For example, think of ball rolling down from top of hill in a box shape space.
If you push the ball back to top of hill again,
you have basically reset the time in the box space with cost of your energy.
Or if ball and hill is made of mud, if you crush both ball and hill and make whole
thing again with ball at the top of hill, again time in the box is reset with cost of
outside energy. In either case, time reset is limited to within the box.
Time travel for everything would be impossible, since there would be no outside
energy then for reversion or reformation.
For that future issue, I assume you meant human for that "no one".
Future is just reorganization of present, as present is to past.
And that reorganization has rules those can't be violated.
Everything interacts with others resulting cause-effect chain.
We can caculate how two balls will act if we have information like mass of ball and etc.
It would be same for universe, but there's just too damn many balls to calculate.
It's just how I think, no theory or anything to support.

I think at some time in our future it may become possible to view the past, I don't believe that any energy dies therefore by some means it should be able to be found and either viewed or heard. I don't believe that a physcial body is able to transcend and go back. If you think on the sub atomic level you would essentially be trying to take back atoms, energy, etc, your body, that is made from molecules that are being used by someone else in that space time. i.e the chicken you ate last week whose atoms are now spread throughout your body.

Thank you. All very good points. I really rever looked at it that way.
btw, aquatus1, isn't the fourth dimension when we are able to freely pass through objects and people and forces? (like a ghost might, or similar to an OBE) I always thought that the fourth dimension was just the third dimension save that free movement unrestricted by the laws of physics, in general, was possible. I thought of the fifth dimensionas moving freely through time. Huh. Hmmmmmmmm....

Mmm...not quite...
The idea of being able to pass through physical objects is still thinking in three-dimensions. Dimensional perception needs to go beyond that, in that everything that we understand as reality changes. In other words, alternate dimensions aren't the same as alternate timelines, in which things are mostly the same, with the occasional physical law change...
I'm afraid that it'll be difficult for me to explain from the middle, so I give everyone fair warning right now that I am about to go into a long metaphorical explanation of dimensional perception, with a limited understanding of the physics behind it, and you should feel free to ignore me completely if you disagree (or, for that matter, even if you don't).
We start at 0 point. No dimensions. No up, no down, no backwards, no forwards, no front, no back. Assuming a sentient population existed (let's call them lemmings), they would be unable to conceive of anything as being around them. Their entire reality is that everything exists within themselves; there is nowhere else for anything to exist.
But now, let us move from our 0 point in a random direction. We have just penetrated to the 1st dimension. We now have forward an backward. Our lemmings are now lined up one behind the other. These lemmings have no sides, just a front and back. For any given creature, the only things it will ever be able to perceive is either the front or the back of the creature in front of or behind it. Seeing beyond that is impossible.
Now we square the first dimension. If we started with one point, went to two points (a line) for the 1st dimension, now we square it to four points, creating the 2nd dimension, a plane. Now we have forward, backwards, and side to side. There is still no up and down, but the lemmings can wander freely about, getting to know everybody.
Square the dimension again. Now we have the multiplanar dimension, our own little niche, our 3rd dimensional world. We have up, down, side to side, and backwards and forwards.
Square it yet again. 4th dimension, Time. Up, down, side to side, backwards forwards, past to future. A lemming of the fourth dimension, can, at will, be anywhere in the timeline that it chooses to be at. To it, there is no such thing as cause and effect, or past, present, and future. Time is not linear in the fourth dimension; it is an actual direction to move through.
Square it again. 5th Dimension, Tesseract, or a wrinkle in Time. If you can think of everything up to the 4th dimension making up the components of a single timeline, then the 5th dimension is all the infinite timelines that could ever exist. A seperate timeline for every possible outcome in reality, and the ability to move from one to the other at will.
There are 11 to 13 dimensions theorized within physics. I'll stop here because I've reached the limits of my knowledge as to their aspects. Each dimension affects the dimension below it, but the effects can only be perceived by the lower dimensions limits of reality. Even within these limits, however, the 5th dimensional creature would be displaying powers of magical proportions. Let's say that we have a sentient marble from the 5th dimension with the ability to insert itself through the others. To a creature of the 1st dimension, as the marble crossed the single point line of its existence, what he would suddenly see is not the lemming that he has always known, but the marble. In the 2nd dimension, as the sphere crossed the plane phase, the two dimensional lemming would see a dot suddenly appear and expand into a huge circular wall, then shrink again into a dot before disappearing. In the 3rd dimension, we would see a sphere suddenly grow from nowhere into a full fledged sphere, then shrink again into nothingness. In the fourth dimension, the sphere would appear, fully formed, at any point in time.
I realize that this is a fairly ruthlessly compressed version of dimensional theory, and I apologize. If you have any questions that I haven't answered, please feel free to ask.
