Question about dimensions?

Question

Hello everyone thanks for posting your comments on my page. I am hoping to gain some knowledge about how how other dimensions can exist beyond the 3 dimensions that we exist in. I don't know alot about it, but i was hoping someone could explain how we can prove that there are other higher dimensions and are they spatial? or are they different somehow like in terms of time, energy, or something else? Please try and break it down to me in Lay mens terms thankyou.

Answer 1

Answerer vahucel is absolutely correct. n-space, as it is sometimes called, is a math tool for describing functions made up of independent variables. In 3-space, the independent variables are sometimes called height, width, and depth. Using the correct function, we can use the values of these three variables to calculate volume.

When we go beyond 4-space (including time), we enter into an imaginary world in the sense we cannot hope to observe it. At best, we can model it in 4-space and hope to infer how things in 5 and above space function.

One of your answerers suggests you read "The Elegant Universe;" I also recommend it. Brian Greene, the author, is superb at modeling n-space in 1, 2, and 3 space so we can get an inkling of what's going on in 11-space (the super string dimensions).

As an example, suppose you are an inch worm on a clothes line. As far as you can tell, you are in 1-space, fore and aft is all you can move. But a second dimension, around the line, is hidden from your view. Yet it is there. That's how many, if not all, those extra dimensions in string theory are explained...they are curled up very small; so we can't perceive them.

Answer 2

Physical dimension have to do with the shape of the things we touch.This is described in solid geometry.We have basically three dimensions do describe a sphere.And we are able to measure dimension always relative to a point or location.We work in a three dimensioal World and when our time is up we go into another dimension which we do not understand.
Mathemathically we can express space into imaginary dimension and we can perform intergation of calculus in n dimensions having n variables. On that basis we can describle any dimensions in an imaginary volume.
Relativity theory Used 9 dimensions,and presently Strings theory is using 26 dimensions =take your pick.

Answer 3

Have you read or watched "The Elegant Universe" by Brian Greene? It might make it very clear... best to watch it than read it. I think the guy was saying these "other" dimensions are in terms of energy something we cannot see. So if you ask me we can't prove it now due to the fact that string theory is in one big knot. Maybe some day we will be able to prove it, but we will not be alive to see the day.

Answer 4

In Math we can use dimensions of any size. It is called Numerical Space.
Dimension 1, you have when working with equations of one variable... like 2x-6= 0. The solution is a point in x-axe

Dimension 2, you have when working with equations of two variables... like x+y = 6. The solution is a set of point (x,y) plotted in the plane xOy. It is a straight line.

Dimension 3, you have when working with equations of three variables... like x+ y - z = 3. The solution is a set of points (x,y,z) plotted in the plane xyz.

So, you can work with whatever dimension you want. For example, if you are working with a problem that involve an equation of 7 variables you are in dimension 7.
x+y-z+w+u+t-z= 12 the solution is a set of points (x,y,z,w,u,t,z). In this case is not possible to plot a graph of the function.

Answer 5

Look for a book called "Warped Passages" by Lisa Randall. She's a theoretical physicist who has worked at Harvard, MIT, and Princeton.

Answer 6

Hi,friend,how many diamension is there ?it is question which confuse scientist yet,,,according to Einstein our universe is not three diamentional, forth one is also present whichis TIME,,,Also now according to string theory our universe is 11 diamensional,,,so no one exictly that how many diamension is there???????

Answer 7

yes i agree with goring they are n -dimensions , according to string theoty 26 -dimensions , but there are more
