In Cosmic Jackpot, Davies argues that certain universal fundamental physical constants are precisely adjusted to make life in the Universe possible: that we have, in a sense, won a "cosmic jackpot," and that conditions are "just right" for life, as in The Story of the Three Bears. As Davies writes elsewhere, "There is now broad agreement among ...
Cosmic View: The Universe in 40 Jumps is a 1957 book by Dutch educator Kees Boeke that combines writing and graphics to explore many levels of size and structure, from the astronomically vast to the atomically tiny. The book begins with a photograph of a Dutch girl sitting outside a school and holding a cat.
The Universe for Beginners, republished as Introducing the Universe, is a 1993 graphic study guide to cosmology written by Felix Pirani and illustrated by Christine Roche.The volume, according to the publisher's website, "recounts the revolutions in physics and astronomy," from "Aristotle to Newton," and, "Einstein to Quantum Mechanics," "that underlie the present-day picture of the universe."
Astrophysics for People in a Hurry is a 2017 popular science book by Neil deGrasse Tyson, centering around a number of basic questions about the universe. Published on May 2, 2017, by W. W. Norton & Company , the book is a collection of Tyson's essays that appeared in Natural History magazine at various times from 1997 to 2007.
The physical universe is defined as all of space and time [a] (collectively referred to as spacetime) and their contents. [10] Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space.
More precisely, the Hartle-Hawking state is a hypothetical vector in the Hilbert space of a theory of quantum gravity that describes the wave function of the universe.. It is a functional of the metric tensor defined at a (D − 1)-dimensional compact surface, the universe, where D is the spacetime dimension.
Tolman's test compares the surface brightness of galaxies as a function of their redshift (measured as z). Such a comparison was first proposed in 1930 by Richard C. Tolman as a test of whether the universe is expanding or static. It is a unique test of cosmology, as it is independent of dark energy, dark matter and Hubble constant parameters ...
The principle of plenitude asserts that the universe contains all possible forms of existence. Arthur Lovejoy, a historian of ideas, was the first to trace the history of this philosophically important principle explicitly. Lovejoy distinguishes two versions of the principle: a static version, in which the universe displays a constant fullness ...
