CGh physics

cGh physics refers to the mainstream attempts in physics to unify relativity, gravitation and quantum mechanics, in particular following the ideas of Matvei Petrovich Bronstein and George Gamow. The letters are the standard symbols for the speed of light (c), the gravitational constant (G), and Planck's constant (h).

If one considers these three universal constants as the basis for a 3-D coordinate system and envisions a cube, then this pedagogic construction provides a framework, which is referred to as the cGh cube, or physics cube, or cube of theoretical physics (CTP). This cube can used for organizing major subjects within physics as occupying each of the eight corners. The eight corners of the cGh physics cube are:

Other cGh subjects include Planck units, Hawking radiation and black hole thermodynamics.

While there are several other physical constants, these three are given special consideration, because they can be used to define all Planck units and thus all physical quantities. The three constants are therefore used sometimes as a framework for philosophical study and as one of pedagogical patterns.

Before Ole Rømer demonstrated that light has a finite speed, it was assumed that the speed of light (c) is infinite. Because of the tremendously large value of c (namely 299792458 metres per second in a vacuum) compared to the speeds of things in our daily experience, the propagation of light seems to us as instantaneous. Hence, the ratio 1/c was hidden from our view making relativistic mechanics irrelevant. At speeds comparable to the speed of light (c), special relativity takes the finiteness of the speed of light into consideration by the aid of Lorentz transformation. A non-relativistic theory is recovered from a relativistic theory when the limit 1/c is set to zero.
