I'm just kind of curious. We all know about height, width, and depth. And the 4th dimension is time, rite? What is after that? How can you visualize something beyond 3 dimensions?

absolutely not, time is not a dimension, but spacetime is... it has to do with black holes....

In physics, spacetime is any mathematical model that combines space and time into a single construct called the space-time continuum. Spacetime is usually interpreted with space being three-dimensional and time playing the role of the fourth dimension. According to Euclidean space perception, the universe has three dimensions of space, and one dimension of time. By combining space and time into a single manifold, physicists have significantly simplified a large amount of physical theory, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.


Two-dimensional analogy of space-time distortion. The presence of matter changes the geometry of spacetime, this (curved) geometry being interpreted as gravity. Note that the white lines do not represent the curvature of space, but instead represent the coordinate system imposed on the curved spacetime which would be rectilinear in a flat spacetimeIn classical mechanics, the use of spacetime over Euclidean space is optional, as time is independent of mechanical motion in three dimensions. In relativistic contexts, however, time cannot be separated from the three dimensions of space as it depends on an object's velocity relative to the speed of light.

The term spacetime has taken on a generalized meaning with the advent of higher-dimensional theories. How many dimensions are needed to describe the universe is still an open question. Speculative theories such as string theory predict 10 or 26 dimensions (With M-theory predicting 11 dimensions, 10 spatial and 1 temporal), but the existence of more than four dimensions would only appear to make a difference at the subatomic level.

No one can visualize higger dimensions, how ever you can have an idea about how would it be to move in the fourth spatial dimension:

- Imagine you are in the center of an sphere. Now imagine you can move in a direction such that you can allways stay in the center of the sphere, but still moving... There is the fourth dimension.

There ARE other dimensions, in fact there are 11 dimensions
in the universe. The problem is just that the other 7 dimensions (one it's time) are curled up in the structure of space.

This dimensions are very short in lenght (the common 3 dimensions have a very long lenght so yopu can move in the space without encountring any border) so we can't feel them, but there are there!!

Well after that i believe is a diagonal crosssection. But I believe that there are a lot of dimensions so large that they are unmeasurable and so small that you will never find them. But i also belive that multiple universes exist, and that must mean that there has to be more than three dimensions. I believe, based on einstien's theory (that more massiveobjects bend the gridwork of a dimension more) that black holes are so massive that they bend it so much that it punctures the gridwork of the dimension. Therefore leaving a hole that might connect two universes. But the has got to be more than three dimensions.

no no no no no no no !!!!
time is NOT a dimension. it is a man made ordinal device so we can talk about our limited perceptions in a linear fashion....like , when is dinner ready.

each dimension relates DIRECTLY to the previous one.

Here we go:

Zero-D : a point . no dimension...almost an abstraction...represented as a dot.
..........move it at a right angle to itself.........you get....

One-D : a line . one dimension=lenght.
..........move it at a right angle to itself.........you get....

two-D : a plane . two dimensions lenght & width.
..........move it at a right angle to itself.........you get....

Three-D : a cube .your starting to get this....wait.....
..........move it at a right angle to itself.........you get....

Four-D : ....problem....i'm a 3-D object , and i can't point to a right angle to myself......that don't mean it ain't there!!!

think about this for a sec. , a 2-d object has no idea where up or down is....it's 2-d....no frame of reference.

Now let this bake your brain for a moment:
the shadow of a line is a point...
the shadow of a plane is a line....
the shadow of a cube is a plane....
the shadow of a 4-D object IS a 3-D object.
YOU are a 3-d object.

dimentionality has this kind of relationship. Time is irrelevent.

we study 4-d objects by computer simulations of their 3-D shadow shapes.

we've 4 dimensions. Time... being the fourth. no person, i think of, can say for helpful if Hell is a measurement. Or if this is even a place. some human beings think of that this is greater of a techniques set, of psychological torture, than a actual realm. individually i think of this is the two...

I don't think *anyone* can visualize multiple dimensions. Even those physicists who work with string theory in which there are as many as 11 dimensions admit they can't get their heads around them.

To go beyond the fourth dimension you have to add a quantity factor...

such as in CD's

one CD is so thick, by so long, by so wide. = H - W - L

When you play it for a given amount of time you get some particular output. = Time.

The Fifth dimension is quantity...As in a stack of 24 CD's.
You have to name the 10th one, for example. This is easily
demonstrated in a Multi-CD Player.

Scientists claim that there are many dimensions beyond the four you mention but I cannot comprehend any of them.

I can't. The fact is that we are 3d beings. If other dimensions exist (which is not a definite), they are probably curled up into such tiny "spaces" that we can't interact with them.
