Are additional dimensions of time possible?

Yes. Wormholes subconciously send a ray of time 100 Million years  later into our universe. Witch means we wouldn't notice that it use to be the dinosaurs time and a quasar or worhole zapped us here now! You can never enter a wormhole once you enter it its portal to time closes and anybody who goes in it is trapped in eternal nothingness.

Based on the relativity theory, there are many studies that are taking place to look into the possibility of traversing the time-space continuum.  As far as I know, we're not quite there yet.  But if and when we are, we should be able to tap into the theoritical "worm-holes" to go into different points in space without having to exume too much time.

we might die  the 4th dimension IS time

Scientifically, time actually exists as a dimension, but a non-spatial one. Our perception of time may not be necessarily cover the whole concept of what time is. It could be possible that time is some type of "substance" even. But it exists as far as the universe and physics is concerned.\nSince our human experience only covers the present time as a "linear continuum", it's hard to understand time in terms of "existence". It's better to try to define first what "existence" means.\nFor example, for the Taoist, nothing actually exists.\nIn my opinion it's better to come up with a reasonable answer to the question then just put that baby to sleep, because you can throw away your time on a philosophical wild goose chase.\nYou can read "The Elegant Universe" and it'll be so mind-boggling that it might make you not worry about it too much.

well i've been wondering for a long time about the nature of time. It seems that since time is the fourth dimension and we are living in 3 dimensions we may never actually understand the nature of time. Physicists say that time and space doesnt exist as such but a combined entity called spacetime exists. Philosophers may have better answers.

Sure!  The third dimension is almost universally believed to exist.\n\nI think you might have meant the fourth or fifth dimensions.  That's a little bit trickier.  The fourth dimension is time, but it is only occasionally convenient to think of it as such.  In some contexts, there's no question that the fourth dimension is time, in others, it's not convenient at all to think of time as another dimension.  That's pretty much my stance on it-- I don't constantly "believe" that time is or is not the fourth dimension.  I usually base view of it on the situation at hand.\n\nThe fifth and other dimensions are even weirder.  They're apparently responsible for mediating the forces we see, curving space to accomodate the accelerations observed.  I'm a little bit skeptical, but maybe a class in general relativity will sway my opinion.

In our three dimensional universe, time is considered the fourth dimension.

"Time" is not a dimension in the same sense that x,y,z,a,b,c, ..etc are spatial dimensions.\n\nThough the human mind is cabable of imagining muti-dimensional space, and can create clever matematical concepts supporting the idea, there is not one whit of physical evidence to support it.  And there is ample evidence to refute it.  \n\nTake gravity, for example.  Measurments show that gravity decreases as the inverse square of the distance from the source, exactly as it should in three-dimensional space.  If there were more than three spatial dimensions, that wouldn't be the case.  So if you want to postulate there are more than three dimensions, you've got to explain why gravity ignores them!\n\nAlso, take ElectroMagnetic Radiation (EMR), which also behaves the same way - i.e. it decreases as the inverse square of the distance from the source, just as it should in three dimensional space.  So if you postulate more than three dimensions, you've got to explain why EMR doesn't know about it!\n\nAs to string theory, scientists proposing it can't agree whether it requires twenty-six dimensions in order for the math to come out right, or "just" ten!  And they all admit there's no known way to prove or disprove the theory itself. That's makes the theory pretty weak. In fact, it makes it almost science fiction! Great mind exercise, but no eidence of reality!\n\nEinstein's theories provide predictions that can be proved or disproved. That's one reason they are so powerful.\n\nSo the jury's still out on multi-dimensional space - and pobably will be for some time to come.\n\nBut it's fun to speculate!  Just don't bet your food money on it!

If there are higher dimensions, we're definitely in them, but we're still confined to our 3 dimensions (lenght, width, and height), note that you cannot control time.

No one is exactly sure how many dimensions there are.  There are theorys that suggest a certain number, such as the String Theory.  Though, I think that it is possible that there are an infinate amount of dimensions, but I don't think anybody will ever know.  If they do eventually figure it out I'm sure we will all be long dead by then.

Time is called a dimension because in Einstein's theory of relativity it makes mathematical sense to do so. Events happen in spacetime, 3 spatial and 1 time dimension. But their orientation in space and time relative to each other, depends on the observer and the relative speeds of the events.\n\nIn Einstein's formulas these dimensions are mixed by transformations depending on the velocities. This works only if we add time as a dimension.    \n\nWill we ever be able to travel to time? Well, weird things happen to the equations close to black holes and their mathematical opposites, white holes. So who knows?\n\nBut I don't think so... suppose sometime in the future time travel will be  invented. Wouldn't we see these travellers once in a while?

I believe yes.. It makes sense, You see all of these dimensions are just directions. If you say that the four dimensions are represented by X,Y,Z,T these are merely directions of dimensions then all of those are travellable (meaning you can travel in those directions). You can go to left & Right (X), You can go Forward & Backward (Y), you can go Up or Down (Z). The questions now is how do you travel through time. According to Albert Einstein if there is anything that can go faster than the speed of light then it will be possible to travel through time. It is actually true becuase our mind can go faster that speed of light that whay our mind can travel through time, sometimes we remember things in our past that the way our mind travels.

I am assuming this question comes from some thought on the 10-11 dimensions needed by string theory. In this occasion these dimensions are not noticable and have been added because they are needed to make the equations work. In three dimensions and time you only have four variables to work with. But now many physicists have noticed that if you increase our dimennsions to 7,8,9,10,11 it gives more mathematical flexibility and enables us to make equations that can unify gravity with the quantum world. Now for what is the seventh dimension, the first three dimensions are the normal spacial dimensions, up/down, right/left, forward/back. There is also a time dimension sometimes noted as the fourth. Then string theory says there should be another 7 dimensions. Where these would be and why we cant see them is still up for debate but current though is that they are extremely small crumpled up dimensions that we cant notice because there small size makes them have a minimal effect on forces and measurements. I would reccomend reading David Greene's books if you are still intersted in the ideas of string theory and such.

It all dependend where you are filling time. In an insane intitution there are people who experience 4 ,5 of more dimentions . so far I have heard of 26 dimensions being filled including many dimentions of time.\nSpace and time have the same thing in common they can be filled both at the same instance!

Some physicists estimate as many as 12 dimensions. \nAbsolutely there's a spiritual dimension that we can not see as long as we dwell in the flesh.

We observe four dimensions everyday, three spatial and time.\nBut...theories such as string theory predict that the space we live in has in fact many more dimensions (frequently 10, 11 or 26), but that the universe measured along these additional dimensions is subatomic in size. As a result, we perceive only the three spatial dimensions that have macroscopic size.\n\nThis is not so strange as it sounds, which I'll show with an example. Imagine you are in an airplane, flying over sea. Seen from a height, the sea looks flat, two-dimensional. But when the plane looses height we start to perceive the waves, that move in a third direction we could not see before.\n\nThe universe could be the same. Four macroscopic dimensions and a few more, hidden ones. We can only perceive them for instance, by the small effects their existence might have on subatomic particles.
