Gravity in the dynamical approach to the cosmological constant
One of the most disturbing difficulties in thinking about the cosmological constant is that it is not stable under radiative corrections. The feedback mechanism proposed in ref. [1] is a dynamical way to protect a zero or small cosmological constant against radiative corrections. Hence, while this by itself does not solve the cosmological constant problem, it can help solving the problem. In th...
متن کاملModified Gravity: Cosmology without dark matter or Einstein’s cosmological constant
We explore the cosmological consequences of Modified Gravity (MOG), and find that it provides, using a minimal number of parameters, good fits to data, including CMB temperature anisotropy, galaxy power spectrum, and supernova luminosity-distance observations. The MOG cosmology predicts a flat universe with an accelerating expansion and an age of ∼14 billion years.

We explore the cosmological consequences of Modified Gravity (MOG), and find that it provides, using a minimal number of parameters, good fits to data, including CMB temperature anisotropy, galaxy mass power spectrum, and supernova luminosity-distance observations. The MOG cosmology is flat and predicts an age of the universe of ∼ 34 billion years.
متن کاملCosmological Constant and Local Gravity
We discuss the linearization of Einstein equations in the presence of a cosmological constant, by expanding the solution for the metric around a flat Minkowski space-time. We demonstrate that one can find consistent solutions to the linearized set of equations for the metric perturbations, in the Lorentz gauge, which are not spherically symmetric, but they rather exhibit a cylindrical symmetry....
متن کاملVacuum energy fluctuations, the induced cosmological constant and cosmological reconstruction in non-minimal modified gravity models
The one-loop effective action for non-minimal scalar modified gravity on de Sitter background with a constant scalar field is found. The corresponding induced cosmological constant is evaluated. It is shown that quantum effects in non-minimal modified gravity may induce an early-time de Sitter universe even in the situation when such solution does not occur on the classical level. Classical rec...
