A Consistency Condition for Quantum Gravity
Mar 14, 2019 11:00 AM to Mar 14, 2019 12:00 PM at
My talk is on the Consistency Condition—a quantum gravity approach partially developed by Nobel Laureate Richard Feynman, and put into its complete and final form by our own CPP emeritus professor, John Fang, who I studied under for several years. Our efforts led to publication in "Letters of Mathematical Physics." Overall, this approach allows one to construct a valid Lagrangian for any massless spin particle interacting with spin-2 gravitons. Up-to-date the Feynman-Fang Consistency Condition (CC) reproduces: a) Einstein’s wave equation (please note CC does not require the principle of equivalence to generate Einstein’s field equations). b) The dual string model of Scherk and Schwarz (CC can correctly build the dual-string model in both flat and curved spacetime and show torsion is not an inherent aspect to this string model of spacetime). c) The Callan, Coleman and Jackiw model. d) Yang Mills theory. e) Finally, the algorithmic structure of CC is conducive to the language of computer programming. Once CC is evolved into computational form, many tedious calculations could be performed to produce a quick and accurate results for graviton-particle interactions. For all that attend with a flash drive, they will be provided with a copy of Richard Feynman’s talk given here at CPP circa 1986-1987.
