If the effective global curvature is Even assuming the existence of a realistic concept similar to the cosmological constant, in alternative approaches to quantum field theory [5] one can expect it to be generated only in the presence of standard matter. Nameless says: November 21, 2012 at 4:48 pm. Or indeed the Quantum Field, Higgs Field, New Luminiferous Ether, or whatever else we may end up calling it. According to modern 'quantum field theory' apparently empty space is not really empty at all, but is teeming with pairs of 'virtual' particles that come in and out of existence continuously. 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. The question of the space curvature is a major one, but measuring it at large cosmological scales may be extremely difficult if the actual Universe is much larger than the observable one. As explained in the discussion of the stress-energy curvature in the previous post, in addition to the gravity mediators (gravitons) presumably being quantized rather than a continuous or continuum curved spacetime, there is the Quantum field theory is suggestive that the correct Feynman diagram for any interaction is not a continuous, smooth curve, but instead a number of steps due to discrete interactions of the field quanta with the charge (i.e., gravitational mass). As an addendum, it is also interesting to note that Hawking radiation is a direct consequence of quantum field theory in curved space-time. Black Holes Conserve Information in Curved-Space Quantum Field Theory Christoph Adami 1,2,3 andGregL. Davies: Quantum Fields in Curved Space (Cambridge University Press, New York, 1986) Chap. And have studied quantum information transmission in the presence of a black hole. One member of a virtual-particle pair will In this theory there is no 'gravitons' or undiscovered particles, objects just free-fall (gravity) towards the greatest mass because it has the slowest rate that time flows and the greatest curvature of spacetime.

Its also in the lecture series he gave, “Quantum FIeld Theory in Curved Spacetime and Black Hole Thermodyanmics”. This curvature is very small, and its effects are hardly noticable in everyday life and over small distances.
