He poses the question whether in the times of ultimate expansion of the Universe with extremely low density of matter some structures could exist that can support the life of the entities he calls the "Diffuse Ones". He also discussed the possibility of life without sunlight/starlight, e.g., on the surface of brown dwarfs.
The UniverseMachine (also known as the Universe Machine) is a project carrying out astrophysical supercomputer simulations of various models of possible universes, created by astronomer Peter Behroozi and his research team at the Steward Observatory and the University of Arizona.
Even if it is assumed that only one out of a billion of these stars has planets supporting life, there would be some 6.25 billion life-supporting planetary systems in the observable universe. A 2013 study based on results from the Kepler spacecraft estimated that the Milky Way contains at least as many planets as it does stars, resulting in 100 ...
The authors also argue that due to the immense size of the universe, even if another habitable planet like Earth does exist elsewhere, meaning that the Earth is not the only planet in the universe with complex life, such planets would still only appear in relatively small numbers compared to planets that are habitable only to bacteria. Such ...

The companion web site to the book contains articles and video clips on astrobiology produced by the author, as well as a glossary and links to other relevant sites. [2] The book begins with a review of the cosmic setting for life and reviews the insights of astronomy since Copernicus. The discovery that we live in a "biological universe" would ...
Panspermia is the hypothesis that life exists throughout the universe, distributed by meteoroids, asteroids, comets [1] and planetoids. [2] It does not attempt to explain how life originated, but shifts the origin to another heavenly body.
The observable universe contains as many as an estimated 2 trillion galaxies [95] [96] [97] and, overall, as many as an estimated 10 24 stars [98] [99] – more stars (and earth-like planets) than all the grains of beach sand on planet Earth; [100] [101] [102] but less than the total number of atoms estimated in the universe as 10 82; [103] and ...
