You are referring to string theory I believe. All the hinger spacial dimensions are curled up on each other in a very small area. This makes them too small to be seen which is why we don't notice them. To get a decent understanding of this think of power line. To someone our size it just has two dimensions, it's height and length. But to an ant walking on it it has three. It can freely walk all the way around the power line in a way that we cannot. The same goes for these higher dimensions. Hope this helps!

BTW, these dimensions come about mathematically in order to solve certain equations in cosmology. Don't try to give them too much of a physical meaning like these other people are trying to do.

We have been partly unsuccessful with the standard 4 (length, width, height and time.) In very small space, quantum space, those four dimensions break down, or at least are insufficient.

Yet we perceive only four at the big size of humans to universes. It is possible the other dimensions are hidden, maybe rolled up so they only have a visible effect in the very small spaces of quantum mechanics.

Physicist have looked at various numbers of dimensions to find the fewest that would describe the observations we see. Eleven seems to be the magic number de jour.

Any way, if you have eleven dimensional space expressed as a flexible membrane, where two of these flexi-branes intersect, we would see the strings of string theory and would forces the extra dimensions to roll into the strings. we get a new description of our universe and observations work over a wider range of sizes than standard relativity or quantum mechanics can explain on their own.

Ah, to be human. To be the one creature smart enough to understand a great chunk of the universe, and also smart enough to understand that we cannot inherently comprehend a great deal about the way the universe works.

As for dimensions, I would suggest that they are simple modes of getting from point A to point B.

1. Vertical
2. Horizontal
3. Depth (either out or in)
Those three take us to any physical space we could desire by combining them in the right amount.
4. Time --- as we currently experience it we travel through time going "forward" so time exists on a horizontal axis.
5. Vertical Time. Just as you can graph a physical place through time, you can plot a single moment/place in spacetime on another axis called verticle time (or sideways time)
6. Depth Time. Same concept as above.

7. Hyperspace. the dimension through which you can sequentially move through non-adjacent placed
point a, point f, point c, point q, etc.

8. Hypertime. The dimension through which you can sequentially move through non-adjacent times.

9. Subspace. Take an infinitely small single dimensional point. now, divide it, and move towards the center. divide that center point and move towards the center again.

10. Subtime. Same concept, but with moments.

11. Null Dimension, Negative Dimension, Nothingness.

Once you understand what the word 'dimension' actually means, it will all make sense. Right now you're trying to 'see' a dimension as a 'distance' or a 'metric'. And it isn't any of those. It's a linearly independent value which cannot be 'derived' from the other dimensions. Nothing more, nothing less.

An object only takes up 3 dimensions at any one time... 11 dimensions sounds like your teacher is wanting some sort of ridiculous metaphysical answer or something.

well lets see
1.higth
2.with
3.depth
4.outside
5.inside
6.subspace
7.hyperspace
8.past
9.present
10.future
11.zero dimension
but they can all be used to triangulate witch would be lots more dimensions
lol
