how many dimensions are there of time only?

Answer 1

Your answerers are thinking inside the box I'm afraid. While conventional wisdom would say there is but one time dimension, unconventional thought, like string theory, allows for multiple time dimensions because it allows for parallel universes, each with its own time lines. [See source.]

And some truly unconventional thought even suggest multiple dimensions for time in our own universe. Check this out:

"Or, speaking in terms of dimensions, the four corners occupy 2 dimensions, and the static opposites occupy 1. Space has 3 dimensions: it's Cubic. Time also has 3 dimensions (one for linear time, the other two for the four corners): therefore, Time is also Cubic.

And time is not linear, because as we've seen, there are 4 Time Corners on a flat plane, even in addition to linear time. This shows that time, in totality, is cubic. So, Time is Cubic, not linear." [See source.]

True, neither the parallel universe nor the time cube theory is falsifiable; so neither can be considered to be a true theory. But even as simply a philosophy, both models pique the imagination outside the box.

Answer 2

Hi,

I'm afraid I don't understand your question. Hopefully this will help:

Classical physics theories describe three physical dimensions: from a particular point in space, the basic directions in which we can move are up/down, left/right, and forward/backward. Movement in any other direction can be expressed in terms of just these three. Moving down is the same as moving up a negative amount. Moving diagonally upward and forward is just as the name of the direction implies; i.e., moving in a linear combination of up and forward. In its simplest form: a line describes one dimension, a plane describes two dimensions, and a cube describes three dimensions.

Time is often referred to as the "fourth dimension." It is, in essence, one way to measure physical change. It is perceived differently from the three spatial dimensions in that there is only one of it, and that movement seems to occur at a fixed rate and in one direction.

edit: - having read the newer replies - I think I see what the question was implying. Even if you could move back and forth through time, it would still remain as one dimension.

Answer 3

Are you referring to space-time continuum? Time in itself is a unit of dimension. In as much as the real wold is 3D in nature, with time a 4th element is added. Be more specific on what you are asking about.

Answer 4

currently, one known, just time, however it is being speculated that some objects move backwards in time, quite confusing yes, and elaboration on this by scientists might result in two or more known dimensions.

Answer 5

One -- it's called "time".

Answer 6

one only
