# Proper size of the visible Universe in FRW metrics with a constant spacetime curvature

@article{Melia2013ProperSO, title={Proper size of the visible Universe in FRW metrics with a constant spacetime curvature}, author={Fulvio Melia}, journal={Classical and Quantum Gravity}, year={2013}, volume={30}, pages={155007} }

In this paper, we continue to examine the fundamental basis for the Friedmann–Robertson–Walker (FRW) metric and its application to cosmology, specifically addressing the question: What is the proper size of the visible universe? There are several ways of answering the question of size, though often with an incomplete understanding of how far light has actually traveled in reaching us today from the most remote sources. The difficulty usually arises from an inconsistent use of the coordinates or…

A particularly attractive feature of inflation is that quantum fluctuations in the inflaton field may have seeded inhomogeneities in the cosmic microwave background (CMB) and the formation of…

On recent claims concerning the Rh = ct Universe

The R_h=ct Universe is a Friedmann-Robertson-Walker (FRW) cosmology which, like LCDM, assumes the presence of dark energy in addition to (baryonic and non-luminous) matter and radiation. Unlike LCDM,…

Testing viable f(R) models with the angular-diameter distance to compact quasar cores.

- PhysicsPhysical review. D.
- 2019

The results show that, while the most popular f(R) models today are consistent with this measurement to within 1σ, the turning point z max will allow us to prioritize these alternative gravity theories as the measurement precision continues to improve, particularly with regard to how well they mitigate the tension between the predictions of ΛCDM and the observations.

The maximum angular-diameter distance in cosmology

Unlike other observational signatures in cosmology, the angular-diameter distance d_A(z) uniquely reaches a maximum (at z_max) and then shrinks to zero towards the big bang. The location of this…
