Вариации гравитационной постоянной в обобщенных теориях гравитации
Abstract
A class of multidimensional theories of gravity where spatial and temporal variations of the gravitational constant G and the fine structure constant α have a common cause and coincide in value is pointed out. Despite the absence of confident observational data on G variations. arguments in favor of their existence, connected with both the problem of unification of physical interactions and with the well-known «faint young Sun» paradox, are presented. The conclusion on possible nonlinear dependence of G from the cosmological time is drawn.
