Theoretical physicists like to ask the big questions: How did the Universe begin? What are its fundamental constituents? What are the laws of nature that govern
21 Απρ 2014 · In the early 1980s, many physicists looked to eleven-dimensional supergravity in the hope that it might provide that elusive superunified theory. In 1984 supergravity was knocked off its pedestal by ten-dimensional superstrings, one-dimensional objects whose v

3 Μαρ 2000 · This book contains six chapters and 33 papers which nicely cover of the evolution 11-dimensional supergravity from its pre-Kaluza-Klein supergravity days to its new incarnation as M-theory.
5 Φεβ 2023 · Universe: The Definitive Visual Guide. From the fiery mass of the Sun's core to the black hole at the center of the Milky Way, Universe takes you on the ultimate guided tour of the cosmos.
The Universe’sUNSEEN DIMENSIONS The visible universe could lie on a membrane floating within a higher-dimensional space. The extra dimensions would help unify the forces of nature and could contain parallel universes Copyright 2000 Scientific American, Inc.
extend the N= 1 super-Poincar e algebra in eleven dimensions. We discuss the steps in the construction of the d= 11 supergravity Lagrangian, present the symmetries of the theory and the relevant transformation rules for the elds. We review the membrane and ve-brane solutions and their properties: the saturation of the BPS bound by the relevant mass
