We can perceive only three dimensions, what does the remaining seven out of the total ten dimension hold?

Question

It is researched mathematecally that there are total of 10 dimensions out of which we can experience 3, what do the remaing seven dimensions hold?

Answer 1

There are two ideas about extra dimensions:
Small extra dimensions and large extra dimensions.
In the first case, all other than the 3 +1 (i.e three spatial and 1 time) dimensions are small and kind of curled into very small scales in the 3 D. Consider a sheet of paper rolled into a cylinder. From close by you will see that the sheet has two dimensions, i.e. the cylinder has a surface. But if the radius of the cylinder is very very small or if you look from a very large distance, you will see that there is only a line, not a cylinder. Thus the 2 dimensional world of the paper sheet is curled into a 1 dimensional line. This is called compactification.

In the large extra dimensional idea, we live in a brane (a subset) of the large 10 dimensional world. For example, the face of a cube is 2 dimensional although the cube is 3 dimensional. Our world and all other things live in a hyper-brane which is 3+1 dimensional and we can not go into the other extra dimensions. This is called brane world scenario.

Answer 2

Physicists believe that the other 7 dimensions are looped back on themselves over very short distances (about the size of a proton), so there's nothing much in those directions. All the real stuff takes place in our 3 dimensions. The other seven are only there to make all the forces balance.

Answer 3

Mathematically you can have any number of dimensions. This way you can have 'N' degrees of freedom and N/2 dimensions.

Try Projective Geometry book.

Point diagram, line diagram and plain diagram (this is a new one I am proposing calling it minootoo proposition for additional Dimension.).

You just define each dimension, then calculations becomes very easy.

See what you come up with.

Answer 4

Honestly, I know that we can experience 3D but we can only imagine the other dimensions and where and how on earth can we experience the others when we don't even know of what it is (it's form) initially?

Answer 5

well, can you perceive the flux of time ? then you are perceiving a fourth dimension.

Moreover there is modified string theory that holds 26 dimensions.

Answer 6

see this link to understand it fully it is about some string theory
