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

Role of stellar physics in regulating the critical steps for life
Manasvi Lingam,Abraham Loeb +1 more
TL;DR: In this paper, the authors apply the critical step model to Earth-analogs around stars of different masses by incorporating the constraints on habitability set by stellar physics including the habitable zone lifetime, availability of ultraviolet radiation for prebiotic chemistry, and atmospheric escape.

Dark matter and dark energy proposals: maintaining cosmology as a true science?
TL;DR: In this paper, the relation of explanations for the observed data to testability in the following contexts was considered: observational and experimental detection of dark matter, experimental detection or experimental testing of the multiverse proposal to explain a small non-zero value of Λ, and observational testing of large scale spatial inhomogeneity with zero Λ.

Exploring a simple sector of the Einstein-Maxwell landscape
Cesar Asensio,Antonio Segui +1 more
TL;DR: In this paper, the authors explore the four-dimensional Einstein-Maxwell landscape as a toy model in which they can formulate a sphere compactification stabilized by an electromagnetic field and obtain a simple sector of the ($2J+2$)-dimensional EMM landscape.
Journal ArticleDOI
The Copernican principle in compact space–times
John D. Barrow,Janna Levin +1 more
TL;DR: In this article, it was shown that the preferred topological frame must also be the comoving frame in a homogeneous and isotropic cosmological space-time, which is the same as the cosmology expansion.
