The Anthropic Cosmological Principle
TLDR
In this article, Barrow and Tipler examined the question of Mankind's place in the universe, taking the reader on a tour of many scientific disciplines and offering fascinating insights into issues such as the nature of life, the serach for extraterrestrial intelligence, and the past history and fate of our universe.Abstract:
Is there any connection between the vastness of the universes of stars and galaxies and the existence of life on a small planet out in the suburbs of the Milky Way? This book shows that there is. In their classic work, John Barrow and Frank Tipler examine the question of Mankind's place in the Universe, taking the reader on a tour of many scientific disciplines and offering fascinating insights into issues such as the nature of life, the serach for extraterrestrial intelligence, and the past history and fate of our universe.read more

Multiverse Understanding of Cosmological Coincidences
TL;DR: In this paper, the authors show that the time scales of structure formation, galaxy cooling, and vacuum domination do not differ by many orders of magnitude, but are all comparable to the present age of the universe.

Naturally Speaking: The Naturalness Criterion and Physics at the LHC
TL;DR: In this paper, a non-technical discussion of the naturalness criterion and its implications for new physics searches at the LHC is presented in the book "LHC Perspectives", edited by G. Kane and A. Pierce.
Journal ArticleDOI
Anthropic predictions for neutrino masses
TL;DR: In this article, it is argued that small values of the neutrino masses may be due to anthropic selection effects, and the combined mass of the three neutrinos species is expected to be {approx} 1 eV, causing a non-negligible suppression of galaxy formation.
Journal ArticleDOI
Anthropic Shadow: Observation Selection Effects and Human Extinction Risks
TL;DR: A significant practical consequence of taking anthropic biases into account in deriving predictions for rare stochastic catastrophic events is described, and some directions for future work are suggested.

Cosmological constraints on a dynamical electron mass
John D. Barrow,João Magueijo +1 more
TL;DR: In this paper, the electron to proton mass ratio was shown to be driven by the electronic energy density after the electron mass threshold is crossed, and it was shown that changes in the electron-proton ratio were driven by changes in energy density.
