11th dimension may refer to: 11-dimensional supergravity , a field theory that combines the principles of supersymmetry and general relativity. 11-dimensional spacetime, which appears in M-theory , a proposed "master theory" that unifies the five superstring theories
In string theory, spacetime is ten-dimensional (nine spatial dimensions, and one time dimension), while in M-theory it is eleven-dimensional (ten spatial dimensions, and one time dimension). In order to describe real physical phenomena using these theories, one must therefore imagine scenarios in which these extra dimensions would not be ...
Due to string dualities, the conjectured 11-dimensional M-theory is required to have 11-dimensional supergravity as a "low energy limit". However, this doesn't necessarily mean that string theory/M-theory is the only possible UV completion of supergravity; [ citation needed ] supergravity research is useful independent of those relations.
M-theory aims to unify quantum mechanics with general relativity's gravitational force in a mathematically consistent way. In comparison, other theories such as loop quantum gravity are considered by physicists and researchers to be less elegant, because they posit gravity to be completely different from forces such as the electromagnetic force.
Ageism is a social inequality resulting from age stratification. This is a sociological concept that comes with studying aging population. [ 3 ] Age stratification within a population can have major implications, affecting things such as workforce trends, social norms, family structures, government policies, and even health outcomes.
Superstring theory is not the first theory to propose extra spatial dimensions. It can be seen as building upon the Kaluza–Klein theory , which proposed a 4+1 dimensional (5D) theory of gravity. When compactified on a circle, the gravity in the extra dimension precisely describes electromagnetism from the perspective of the 3 remaining large ...
