Matthews, and Nobel laureate Frank Wilczek, who have created scientific models where the Big Bang and thus the entire universe could arise from nothing but a random quantum vacuum fluctuation in the quantum field -- via natural processes. €�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.

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. 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. All objects move without additional external force along a straight line in curved spacetime and the geometry of the spacetime is dictated by the present mass/energy" . This test with observing radio data from dstant quasars lensed by the solar gravity field puts gamma as unity to four orders of magnitude. Quantum Field Theory in Curved Space Tim. Has the greatest theoretical physicist of all time really missed the bandwagon of quantum physics? Quantum field theory on curved spacetime , Lecture notes in physics, Springer (2009). While quantum mechanics may be formulated for a wide range of physical systems, interpreted as particles, extended particles and fields, the quantum mechanics of fields is often called the quantum field theory and the quantum mechanics of systems of a fixed finite number of particles is often view as the quantum mechanics in a narrow sense. 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. 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. Know that the above stuff converges properly to something which makes sense. There's actually a we call it a tensor (1,2). 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. 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). Michio Kaku, Alan Guth, Alex Vilenkin, Robert A.J. And have studied quantum information transmission in the presence of a black hole. Uniting gravity theory with quantum theory is a major goal of 21st-Century physics, . 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.
