How does string theory explain dimensions?

How does string theory explain dimensions?

String 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.

What does string theory say about multiple dimensions?

String theory smooths out the mathematical inconsistencies that currently exist between quantum mechanics and the theory of relativity. It posits that the entire universe can be explained in terms of really, really small strings that vibrate in 10 or 11 dimensions — meaning dimensions we can’t see.

What is the 11th dimension?

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.

What is a simple explanation of string theory?

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops of string, each with its own characteristic frequency.

What is string theory and how can it possibly explain the origins of matter?

String theory is a potential “theory of everything”, uniting all matter and forces in a single theoretical framework, which describes the fundamental level of the universe in terms of vibrating strings rather than particles.

Why does string theory require extra dimensions?

Any more dimensions would result in too much supersymmetry and a theoretical structure too simple to explain the complexity of the natural world. This is reminiscent of Joe Polchinski’s argument (somewhat tongue-in-cheek, somewhat serious) that all attempts to quantize gravity should eventually lead to string theory.

How do you explain the 11th dimension?

The 11th dimension is a characteristic of spacetime that has been proposed as a possible answer to questions that arise in Superstring Theory, which involves the existence of 9 dimensions of space and 1 dimension of time.

Why does string theory need 10 dimensions?

String theory requires that space-time have 10 dimensions; LQG doesn’t work in higher dimensions. String theory also implies the existence of supersymmetry, in which all known particles have yet-undiscovered partners.

How does string theory explain light?

String theory is the idea that everything in the universe, every particle of light and matter, is comprised of miniscule vibrating strings. These strings are truly tiny, many billions of times smaller than an individual proton within an atomic nucleus.

What is string theory trying to prove?

String theory attempts to reconcile general relativity (gravity) with quantum physics. A new connection (called supersymmetry) exists between two fundamentally different types of particles, bosons and fermions. Several extra (usually unobservable) dimensions to the universe must exist.

How many 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.

Are there any problems with the string theory?

The biggest problem with this theory is that it still places God inside the particular cosmos that was created for mankind. According to the latest version of string theory, all eleven dimensions (time, the three spatial dimensions, and seven others that are too condensed to see) are necessary for the universe as we know it.

Where does the number of dimension come from?

The origin of dimension in string theory – the short and not really clear explanation. To understand where the number of dimension comes from one need to understand how strings are quantized. When a string travel in space-time it draws a 2-dimensional surface (1- dimension along the string and 1- dimension is time).

Is it possible to have more than 11 dimensions?

Scientists do not believe there can exist more than 11 dimensions because conditions become unstable and particles naturally collapse back down into 10 or 11 dimensions. The 12th dimension, for example, introduces a second time. While strings can only vibrate in 10 dimensions, membranes can exist at 11 dimensions.
