Coasting Cosmologies with Time Dependent Cosmological Constant
The effect of a time dependent cosmological constant is considered in a family of scalartensor theories. FriedmannRobertsonWalker cosmological models for vacuum and perfect fluid matter are found. They have a linear expansion factor, the so called coasting cosmology, the gravitational ”constant” decreases inversely with time; that is these models satisfy the Dirac Hypotheses. The cosmological ”...
متن کاملBubble Cosmology : A concordant cosmological model ? ⋆
The Fractal Bubble model has been proposed as a viable cosmology that does not require dark energy to account for cosmic acceleration, but rather attributes its observational signature to the formation of structure. In this paper it is demonstrated that, in contrast to previous findings, this model is not a good fit to cosmological supernovae data; there is significant tension in the best fit p...
متن کاملCosmological Constant Seesaw in Quantum Cosmology
Recently a phenomenological relationship for the observed cosmological constant has been discussed by Motl and Carroll in the context of treating the cosmological constant as a 2× 2 matrix but no specific realization of the idea was provided. We realize a cosmological constant seesaw mechanism in the context of quantum cosmology. The main observation used is that a positive cosmological constan...
متن کاملThe Cosmological Constant in Brane Cosmology
We propose, based on brane cosmology, an explicit relation R = MPlR 2 extra of the radius of the observed brane Universe and the extra dimensions for solving both the hierarchy problem and the cosmological constant problem without fine-tuning. This relation associates the dark energy (i.e., cosmic acceleration) in the cosmological physics with the electroweak scale in particle physics, thereby ...
متن کاملIntroduction to Cosmology and the Cosmological Constant
This paper is written for the course apm426S, taught by James Colliander in Spring 2002, University of Toronto. It gives an introduction to cosmology, concentrating on the effects of the cosmological constant Λ in the context of isotropic and homogeneous universe. Solutions to the Einstein’s equation with and without Λ are carefully derived, analyzed and compared. Some current problems with Λ a...
