Since i was young, i have heard about this two concept, but never quite understood. 4 dimension is more sophisticated, the extra dimension is "Time". But where is it? 1st Dimension is "Length", 2nd Dimension is "Width" and 3rd Dimension is "Height".. So how about "Time"? How to explain it?
It has something to do with passing through the space and time right? Like if u can control the 4th Dimension, u can passing to the past or to the future

Okay... so you can basically have as many demensions as you want. First demension is a mathmatical point in space, no mass what so ever. Connect two points at all points and you have a segment (1 demension). Connect two segments at all points and you have a square (two demensions). Connect two squares at all points and you have a cube(three demensions) (you may do this on a peice of paper if you wish). Connect two cubes at all points and you have a hyper cube, otherwise known as a tesseract, this is four demensions. But you could keep going. You could connect two tesseracts and you'd have 5 demension. It goes on forever, but it goes beyond our ablilities to comprehend after a while.
Another thing... You can't pass through time. The only way to pass through time would be to go faster than the speed of light (because the closer you get to light speed the slower time goes, they did this with atomic clocks - one on a tall tower and one deep in the ground, guess which was older). Since nothing can surpase the speed of light you can't move in time (it isn't even for sure that you WOULD go back in time anyway, theoriectically you could just be in nothingness waiting for time to catch up). Anyway, I don't want to go off on a tangent, but maybe you should buy some books. Hawkings "A brief history of time" is very interesting. Hope this helped!

If you had clear plastic box and put a butterfly into that box you would hold a 3 dimensions world for that butterfly. The butterfly can fly up or down - 1 dimension; it can fly away from you or toward you – 2, second dimension; or to your right or left - 3, the third dimension.
If you moved the box the butterfly’s world of 3 dimensions would be the same; but you have added a different real location for the butterfly over the time of your movement of the box.
The 4th dimension is time which can separate you from finding out about the movement of your butterfly as you move away from the box. If you were a light minuet away from the box you would see where the butterfly was one minuet ago, not where the butterfly really was right now, because, time – the speed of light – the 4th dimension separates you from the butterfly. If the sun were to go out, you would not know it for about 8 minutes because it takes light from the sun that long to reach Earth – time the 4th dimension delays events from being known over distances.
My calculations of time in quantum space suggests that time can go only to the future – no time travel; some scientists have other theories, but know one has the proof experiment yet.

I recently heard of a proposal made by an indian physicist to treat the 4th dimension as a sort of figure of energy, or magnitude, because of the way we treat time and how it has been commonly accepted as apart of space; the space-time continuum. But I don't believe there is any solid agreement on what the 4th dimension is.

^Time paradoxes do not occur
Anyways... to understand how time acts like another dimension, think of an ant walking down the length of a rubber band. If you drew little notches along its length overy centimeter beforehand, you could tell how fast the ant was moving along. Now imagine stretching the rubber band, so that the distance between these points increases. It now takes longer for the ant to cross that distance because of the stretching of the surface it is moving on.
In our universe, we move through the "surface" or three spatial dimensions, and one time dimension. Einstien discovered that space warps and stretches in the presense of extreme concentrations of matter or energy. Later, he discovered that not only space, but also time itself (!) behaves in exactly the same manner. The effect is subtle and takes a bit of study to grasp fully, but it is very real.
We only say that it is another dimension because, to all appearences, in all the ways that we can observe the behavior of dimensions; time behaves in exactly the same way as our regular spatial dimensions.
The only way we can "control" any of our dimensions is to move very quickly, or to approach near a very great concentration of mass or energy. In there cases, space and time would be stretched out and we would observe that time in the "outside" world progresses at a slower rate. Likewise, those around us would observe that out time is progressing at a slow rate!
P.S. Time and space only bend one way, but it would really be something if we discovered one day how to bend them the other way ; )
P.P.S. "A brief history of time" is useless if you want a real understanding. I reccomend Brian Green's "The Elegant Universe" instead.

I think of time as the distance between 3d objects. It takes the extra dimension of time to get from point A to point B. That is, even at light speed, it takes a certain amount of TIME, the fourth dimension.
It's easy to go forward in time, but going back would create paradoxes, which are nasty.

Well if you take a line-1st dimension- and turn it, the shadow makes a shadow, it's a dot. If you take a square-2nd dimension- and turn it, it's a line. If you take a cube-3rd dimension and turn it, it's a square. So what would make a cube?
