cGh physics (Physics Dictionary)

cGh physics : Any attempt in mainstream physics to unify existing theories of relativity, gravitation, and quantum mechanics, particularly by envisioning the three universal constants fundamental to each field – the speed of light ( c ), the gravitational constant ( G ), and the Planck constant ( h ) – as the edges of a three-dimensional cube, at each corner of which is positioned a major sub-field within theoretical physics according to which of the three constants are accounted for by that sub-field and which are ignored. One corner of this so-called “cube of theoretical physics”, where all three constants are accounted for simultaneously, has not yet been satisfactorily described: quantum gravity.
