The previous post Is the Cosmological Principle (CP) Valid? suggests the following scientific method to get a Nobel Prize: Make an ad hoc unphysical assumption like CP: The Universe is isotropic and homogeneous. Make observations indicating that CP is not valid. Insist that CP anyway is valid, because a Principle is a principle. To fit […]

The FLWR Cosmological Model The basic mathematical model of cosmology is the FLWR model which is the very simple model resulting from Einstein’s equations assuming the validity of the Cosmological Principle (CP) stating that the Universe on large scales is isotropic (the same in all directions) homogeneous (the same at all locations) or in the formulation […]
