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. Despite of it, the combination of four-dimensional general relativity and quantum mechanics theories can describe some aspects of five-dimensional reality like the small curved patches, which are used for paving of rough surface. Relativity tells us that spacetime is curved, and that curvature causes the force of gravity. If it is a graviton field then it is not the curvature of space-time but the interaction of the graviton force particles. Since there is no complete quantum theory of gravity, they used an established approach called quantum field theory in curved spacetime (QFTCS). A very thin rubber sheet is a pretty good . Spacetime analogs is an emerging field of physics in which scientists investigate systems having mathematical links with general relativity, and test their theories about the early behavior of the universe. If gravity is the curvature of space-time then how can it ever be described by a quantum theory. 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. Obviously space is part of spacetime and so the effect of the curvature of spacetime is usually (but not always) that we can no longer think of space as being flat (mathematically speaking). The prediction of their existence falls out of the Dirac Equation, but Einstein's model accounts for the negative energy states differently than modern quantum field theory does: Once Upon a Spacetime · 3:58 PM. This test with observing radio data from dstant quasars lensed by the solar gravity field puts gamma as unity to four orders of magnitude. Uniting gravity theory with quantum theory is a major goal of 21st-Century physics, . €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. The second input is to take some spacetime manifold (like flat Minkowski space or something more curved) and attach a C*-algebra to each open subset in a compatible way. Please teach me more detail: why we must consider Quantum Field Theory in Curved Space-Time,but do not consider the QTF Theory(e.g Quantum Electrodynamics) in flat space-time with ''gravity coupling'' (mass). A recent study of gamma-ray bursts finds that spacetime is smoother on the quantum scale than expected. Perhaps suggesting a less dense area in space say nearer the center of a galaxy v/s the extreme perimeter light could travel faster or slower until it comes to the field we know and love here called Constants. In field theories of this kind, particles . Then, there is the problem of quantization. Einstein's proposed unified-field equations (fundamental laws of physics) were generally derived from a variational principle expressed in terms of the Riemann curvature tensor for the presumed space-time manifold.
