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."
The Hubble eXtreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed at that time. Except for the few stars in the foreground (which are bright and easily recognizable because only they have diffraction spikes), every speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is ...
Julia M. Klein of Johns Hopkins Magazine wrote, "There's nothing small about Johns Hopkins physicist Sean Carroll's latest undertaking. The Biggest Ideas in the Universe: Space, Time, and Motion is the first volume in an ambitious trilogy that seeks to explain physics to a popular audience—one willing to grapple with the basics of calculus and other mathematical underpinnings of the field.
George's Secret Key to the Universe is a 2007 children's book written by Lucy and Stephen Hawking with Christophe Galfard.Upon its release, the book received mixed reviews, and was followed by five sequels, George's Cosmic Treasure Hunt in 2009, George and the Big Bang in 2011, George and the Unbreakable Code in 2014 and George and the Blue Moon in 2016 and George and the Ship of Time [] in 2018.
Hence, according to Einstein's field equations, R grew rapidly from an unimaginably hot, dense state that existed immediately following this singularity (when R had a small, finite value); this is the essence of the Big Bang model of the universe. Understanding the singularity of the Big Bang likely requires a quantum theory of gravity, which ...
Is the universe homogeneous and isotropic at sufficiently large scales, as claimed by the cosmological principle and assumed by all models that use the Friedmann–Lemaître–Robertson–Walker (FLRW) metric, including the current version of the ΛCDM model, or is the universe inhomogeneous or anisotropic?
George and the Big Bang is a 2011 children's book written by Stephen and Lucy Hawking. The book is the third book in the George series, following George's Secret Key to the Universe and George's Cosmic Treasure Hunt. George and the Big Bang is available in paperback, hardback and audio versions. [1]
Eastern and Western thought differed greatly in their understanding of space and the organization of the cosmos. The Chinese saw the Cosmos as empty, infinite, and intertwined with the Earth. Western ideas, based on the ancient Greeks' understanding of the cosmos, believed in a multi-planar divided cosmos that was finite and filled with air.
