Cosmology for Grand Unified Theories with Radiatively Induced Symmetry Breaking
TL;DR: In this article, the treatment of first-order phase transitions for standard grand unified theories is shown to break down for models with radiatively induced spontaneous symmetry breaking, leading to an explanation of the cosmological homogeneity, flatness, and monopole puzzles.

TL;DR: In this article, the authors present an observational program to determine the dark energy properties as well as possible, based on the observation of the acceleration of the universe, along with dark matter, the observed phenomenon that most directly demonstrates that our theories of fundamental particles and gravity are either incorrect or incomplete.
Journal ArticleDOI
Reheating an inflationary universe
TL;DR: A numerical analysis of the evolution of the Higgs expectation value and the temperature of the universe during the symmetry-breaking phase transition in an SU(5) theory with radiatively induced symmetry breaking is presented in this paper.
Journal ArticleDOI
Time varying speed of light as a solution to cosmological puzzles
Andreas Albrecht,João Magueijo +1 more
TL;DR: In this article, the cosmological implications of light travelling faster in the early universe were considered and a prescription for deriving corrections to cosmology evolution equations while the speed of light $c$ is changing.
