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
Supergravity was discovered in 1976 through the construction of pure four-dimensional supergravity with one gravitino. One important direction in the supergravity program was to try to construct four-dimensional = supergravity since this was an attractive candidate for a theory of everything, stemming from the fact that it unifies particles of all physically admissible spins into a single ...
IIA SUGRA is the dimensional reduction of 11-dimensional supergravity on a circle. This means that 11d supergravity on the spacetime M 10 × S 1 {\displaystyle M^{10}\times S^{1}\,} is equivalent to IIA supergravity on the 10-manifold M 10 {\displaystyle M^{10}\,} where one eliminates modes with masses proportional to the inverse radius of the ...

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.
Textbooks published by NCERT are prescribed by the Central Board of Secondary Education (CBSE) [8] from classes I to XII, with exceptions for a few subjects, especially for the Class 10 and 12 Board Examination. Around 19 school boards from 14 states have adopted or adapted the books. [11]
In the Class 7 textbook topic titled “Our Pasts-2”, pages 48 and 49 have been excluded. These pages mentioned “Mughal Emperors: Major campaigns and events.” The deletions also affected Biology and Chemistry textbooks as the theory of evolution and the periodic table were also purged from class 10 NCERT textbooks.

However, this is a minority view within the string community. Since E 7 is in some sense F 4 quaternified and E 8 is F 4 octonified, the 12 and 16 dimensional theories, if they did exist, may involve the noncommutative geometry based on the quaternions and octonions respectively. From the above discussion, it can be seen that physicists have ...
