I'm curious if there are more than one time dimensions. Maybe, like extra spatial dimensions, the extra time dimensions are too small, or too large to have been observed. Or perhaps there are other 'directions' in time, not just the future and the past.
It appears that in all physical theories about the universe, such as general & special relativity, super-symmetric string theory, M-theory, etc. it is assumed that time only goes in one direction, that is the direction in which entropy increases.
Although not consistent among observers in relative motion (i.e. they won't agree on how much time has elapsed), is it possible for time to have more than one dimension? and would another time dimension be another 'direction' to go in time?
...or what WOULD another time dimension be like?

Experts on these things have suggested that the only complex long term metastable universes that can exist are those with three space and one time OR three time and one space dimensions.
see http://en.wikipedia.org/wiki/Time-space#Privileged_character_of_3.2B1_spacetime
this also contains citations of the root papers that lead to this conclusion
These may be in some way complementary to each other, that is, by exchanging space and time we can get similar results. I feel that this concept may be very significant but to go beyond that here would venture into new theories territory.

Yes, that's really interesting SoulSurfer. You could say that we need the dimensions to have a physics theory. Without 'flux' nothing is measurable.

I propose you introduce only the concept of paired negative and positive time vectors, and infinitely multiple pairs. Then, you can disregard the role of antimatter, as antimatter (as we know it) exists in our (positive) time vector. All we can assume is that the universe in the negative time vector unfolded exactly -- exactly -- as the universe in our positive time vector. In each universe, every particle played exactly the same influence on every other particle in the unfolding.
Consider oscillation -- this depends on your perspective of time. From the perspective of the singularity, it is a complex unfolding in both positive and negative time vectors that sum to -- essentially -- nothing. A zero-sum game, so to speak.
In this view, we can rest assured that whatever matter exists at a point in time in the negative time direction -- in the negative universe -- directly offsets the structure and amount of matter the positive time direction. There is no instability "event" as is proposed in the Nothing Universe Theory.
From this viewpoint, there is no time without matter, and vice-versa. It also helps me to conceptually grasp an infinitely expanding universe. I perceive it to be infinitely expanding only because -- from my limited perspective -- I can only perceive a "positive" flow of time.
I am so comfortable in the beauty of this epiphany, that it regularly reassures me in times of stress. It reinforces my belief in predeterminism. Everything, in the end, amounts to nothing. Or what I tell my friends: "What will happen, can happen." In summary: "Everything is nothing." (Can someone translate this to Latin for me?).

You might find it helpful to take a look at the work of Itzhak Bars.
Itzhak Bars of the University of Southern California in Los Angeles believes that there are two dimensions of time, and has evolved a theory in support of this. Of course, Bars is fully aware of the difficulties involving negative probability and the paradoxes surrounding time travel, but he thinks there may be constraining symmetries that could overcome these potential problems.

No, but will this do instead?
