Has the greatest theoretical physicist of all time really missed the bandwagon of quantum physics? Uniting gravity theory with quantum theory is a major goal of 21st-Century physics, . Well, the issue is that professor Wisdom's 'breaststroke' is not particularly effective to overcome earth's gravity, as it relies on the local curvature of spacetime. For more information about the spin connection in the language of quantum field theory, Bertlemann's “Anomalies in Quantum Field Theory” seems very comprehensive. So, in this article, we'll stick with a curved 2 dimension spacetime to illustrate Einstein's general relativity, like the one on the right, where I drew a possible trajectory in spacetime. More precisely, a tensor (1,2) is a a linear operator that maps a point, a linear form field and two vector fields with a real scalar. This curvature is very small, and its effects are hardly noticable in everyday life and over small distances. The fancy new piece of machinery (by then an old hat for string theorists and a really old hat for relativists) was the spin connection which allows us to connect the flat-space formalism for spinors to curved spaces. €�Measuring the curvature of space caused by gravity is one of the most sensitive ways to learn how Einstein's theory of General Relativity relates to quantum physics. This test with observing radio data from dstant quasars lensed by the solar gravity field puts gamma as unity to four orders of magnitude. 'Sketchy', in my own sense that some approximations have to be made in the classical solutions of the field equations in the background of a curved space-time and bring these over to the context of a quantum field theory. First to show how to place fermion fields in the bulk. Or indeed the Quantum Field, Higgs Field, New Luminiferous Ether, or whatever else we may end up calling it. There's actually a we call it a tensor (1,2). The Field Equations control the curvature of space-time and represent our theory of gravity, while the Yang-Mills and Dirac equations represent the theory of particle interactions on a quantum level. Know that the above stuff converges properly to something which makes sense.
