Скачать или смотреть The Scalar–Tensor Theory of Gravitation - AI Podcast

Podcast explores the scalar-tensor theory of gravitation, which is an alternative to Einstein's general relativity. It proposes that gravity is not solely mediated by a tensor field, but also includes a scalar field, known as the "dilaton". Podcast examines various theoretical models for the origin of this scalar field, including Kaluza-Klein theory, string theory, and brane theory. It discusses the consequences of this theory for cosmology, specifically concerning the accelerating universe and the time-variability of physical constants. Podcast delves into the mathematical formulation of the scalar-tensor theory, including the prototype Brans-Dicke model, and examines the constraints on the theory's parameters derived from observations.
