Why does string theory have 11 dimensions?
In string theory, the multiverse is made of different dimensions but the highest is 11th dimension. Beyond 11 dimensions, the universe would become unstable and dimensions higher than 11 would collapse to an 11-dimensional universe.
Why does string theory require 10 dimensions?
String theory requires 10 dimensions because it doesn’t work in any other number of dimensions. Roughly speaking, the problem is that the classical string has a certain very important symmetry, and this symmetry is broken when you try to describe a quantum string.
What are the 26 dimensions of string theory?
The 26 dimensions of Closed Unoriented Bosonic String Theory are interpreted as the 26 dimensions of the traceless Jordan algebra J3(O)o of 3×3 Octonionic matrices, with each of the 3 Octonionic dimenisons of J3(O)o having the following physical interpretation: 4-dimensional physical spacetime plus 4-dimensional …
How many dimension are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time.
Is there a 26th dimension?
What is an 11th dimensional being?
The 11th dimension is a characteristic of space-time that has been proposed as a possible answer to questions that arise in superstring theory. According to superstring theory, all of the elementary particles in the universe are composed of vibrating, one-dimensional mathematical objects known as strings.
How many types of dimensions are there in string theory?
The number of dimensions varies (10, 11, 26) with the specific sub-group of string theory or M-theory you are referring to, but they all have the same three types of dimensions. Three spatial dimensions.
What are some criticisms of string theory?
Initially people took this to be a criticism of string theory. If it predicts 10 dimensions and you look around and only see four (three spatial dimensions and one time dimensions) then you might ask: “Where are the other six dimensions?” But Kaluza and Klein had solved that problem 60 years earlier: they rolled the other dimensions up.
Does string theory predict the number of dimensions of spacetime?
Image © R. Dijkgraaf. But string theory has one very unique consequence that no other theory of physics before has had: it predicts the number of dimensions of spacetime. For the mathematics of string theory to be consistent, the number of dimensions of spacetime must be 10. Initially people took this to be a criticism of string theory.
What is the difference between bosonic string theory and M theory?
One notable feature of string theories is that these theories require extra dimensions of spacetime for their mathematical consistency. In bosonic string theory, spacetime is 26-dimensional, while in superstring theory it is 10-dimensional, and in M-theory it is 11-dimensional.
