Dark Energy, Anthropic Selection Effects, Entropy and Life
Chas A. Egan
<PART1> According to the standard LCDM model, the matter and dark energy densities (rho_m and rho_DE) are only comparable for a brief time. We address the cosmic coincidence proble…
A Larger Estimate of the Entropy of the Universe
Chas A. Egan, Charles H. Lineweaver
Using recent measurements of the supermassive black hole (SMBH) mass function, we find that SMBHs are the largest contributor to the entropy of the observable universe, contributin…
A comprehensive comparison of the Sun to other stars: searching for self-selection effects
Jose A. Robles, Charles H. Lineweaver, Daniel Grether +5
If the origin of life and the evolution of observers on a planet is favoured by atypical properties of a planet's host star, we would expect our Sun to be atypical with respect to…
Dark-Energy Dynamics Required to Solve the Cosmic Coincidence
Chas A. Egan, Charles H. Lineweaver
Dynamic dark energy (DDE) models are often designed to solve the cosmic coincidence (why, just now, is the dark energy density , the same order of magnitude as the matter d…
The Cosmic Coincidence as a Temporal Selection Effect Produced by the Age Distribution of Terrestrial Planets in the Universe
Charles H. Lineweaver, Chas A. Egan
The energy densities of matter and the vacuum are currently observed to be of the same order of magnitude: . The cosmological windo…
