Institute For Gravitation And The Cosmos Loop Quantum Gravity String theorists on being asked about alternative theories for quantum gravity … more. This was precisely the insight of edward witten [1] who noticed that computing loop dependent quantities in chern–simons and other three dimensional topological quantum field theories one could come up with explicit, analytic expressions for knot invariants.
Quantum Loop Gravity Insights Challenges Theory Edward witten is the most influential string theorists in the world, is now doing research into gravity that is decidedly non string, and very similar to lqg. @theoriesofeverything quantum gravity in 8 minutes ed witten on loop quantum gravity. Edward witten (born august 26, 1951) is an american theoretical physicist known for his contributions to string theory, topological quantum field theory, and various areas of mathematics. he is a professor emeritus in the school of natural sciences at the institute for advanced study in princeton. [3] witten is a researcher in string theory, quantum gravity, supersymmetric quantum field.

Workshop on spacetime and quantum information topic: a background independent algebra in quantum gravity speaker: edward witten affiliation: institute for advanced study date: december. It consists of interviews about quantum gravity put together by dutch string theorist jay armas, starting in 2011. the scale of this project is immense: there are 37 interviews, most of them rather long and detailed, making up a book of 716 pages. At its heart is the central lesson of gr: gravity is a manifestation of spacetime geometry. thus, the approach emphasizes the quantum nature of geometry and focuses on its implications in extreme regimes near the big bang and inside black holes where einstein's smooth continuum breaks down. In gravity, at least in a closed universe or in a typical cosmological model, there is no one who can probe the system from outside so an algebra only has operational meaning if it is the algebra of operators accessible to some observer.
