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 ...
Since then, a number of organisations and researchers have adapted the dimensions of wellness into their health programs, including the US Substance Abuse and Mental Health Services Administration, which includes two more dimensions of wellness—environmental and financial—along with the original six.

While eleven-dimensional supergravity is the unique supergravity in eleven dimensions at the level of an action, a related theory can be acquired at the level of the equations of motion, known as modified 11D supergravity. [nb 9] This is done by replacing the spin connection by one that is conformally related to the original. [14]
Edward Witten has popularised the concept of a theory in 11 dimensions, called M-theory, involving membranes interpolating from the known symmetries of superstring theory. It may turn out that there exist membrane models or other non-membrane models in higher dimensions—which may become acceptable when we find new unknown symmetries of nature ...
The following areas are assessed through questions asked by the nurse and medical examinations to provide an overview of the individual's health status and health practices that are used to reach the current level of health or wellness. [1] [2] Health Perception and Management; Nutritional metabolic; Elimination-excretion patterns and problems ...
However, for string theory to be mathematically consistent, the strings must live in a universe with ten dimensions. String theory explains our perception of the universe to have four dimensions (three space dimensions and one time dimension) by imagining that the extra six dimensions are "curled up", to be so small that they can't be observed ...
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 Introduction to M-theory "11th Dimension" (song), by Julian Casablancas, 2009
The Grand Design is a popular-science book written by physicists Stephen Hawking and Leonard Mlodinow and published by Bantam Books in 2010. The book examines the history of scientific knowledge about the universe and explains eleven-dimensional M-theory.
