familiar from quantum mechanics but interpreted in this context as coordinates of a quantum space or spacetime. These relations were proposed by Roger Penrose in his earliest spin network theory of space. It is a toy model of quantum gravity in 3 spacetime dimensions (not the physical 4) with a Euclidean (not the physical Minkowskian) signature.
In theoretical physics, quantum field theory in curved spacetime (QFTCS) [1] is an extension of quantum field theory from Minkowski spacetime to a general curved spacetime. This theory uses a semi-classical approach; it treats spacetime as a fixed, classical background, while giving a quantum-mechanical description of the matter and energy ...
Starting in 2003, ' The Most Beloved Vietnam Television Dramas' Voting Contest (Vietnamese: Cuộc thi bình chọn phim truyền hình Việt Nam được yêu thích nhất) is held annually or biennially by VTV Television Magazine to honor Vietnamese television dramas broadcast during the year(s) on two channels VTV1-VTV3.
The idea of complex spacetime has received considerably less attention, but it has been considered in conjunction with the Lorentz–Dirac equation and the Maxwell equations. [1] [2] Other ideas include mapping real spacetime into a complex representation space of SU(2, 2), see twistor theory. [3]
[31]: 48–50 A spacetime diagram is typically drawn with only a single space and a single time coordinate. Fig. 2-1 presents a spacetime diagram illustrating the world lines (i.e. paths in spacetime) of two photons, A and B, originating from the same event and going in opposite directions. In addition, C illustrates the world line of a slower ...
On certain regions of spacetime (and possibly the entire spacetime) one can describe the points by a set of coordinates. In this case, the metric can be written down in terms of the coordinates, or more precisely, the coordinate one-forms and coordinates.
Group field theory (GFT) is a quantum field theory in which the base manifold is taken to be a Lie group.It is closely related to background independent quantum gravity approaches such as loop quantum gravity, the spin foam formalism and causal dynamical triangulation.
