As an addendum, it is also interesting to note that Hawking radiation is a direct consequence of quantum field theory in curved space-time. Know that the above stuff converges properly to something which makes sense. Since the gravitational field is determined by the curvature of spacetime, that would mean on small scales, space would not be continuous and smooth, but rather would be violently curved and fluctuating up and down. I can't do the math, but I suspect that gravity waves from distant events are unlikely to penetrate spacetime that is locally curved by strong gravitational fields. Davies: Quantum Fields in Curved Space (Cambridge University Press, New York, 1986) Chap. €�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. If gravity is the curvature of space-time then how can it ever be described by a quantum theory. Then, there is the problem of quantization. If it is a graviton field then it is not the curvature of space-time but the interaction of the graviton force particles. Uniting gravity theory with quantum theory is a major goal of 21st-Century physics, . 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. This test with observing radio data from dstant quasars lensed by the solar gravity field puts gamma as unity to four orders of magnitude. Taking this into effect, then, requires, at the very least, a massive rewriting of quantum mechanics, as it could no longer treat space and time as fixed parameters. 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.
