The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. The notion of an expanding universe was first scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations. The earliest empirical observation of the notion of an expanding universe is known as Hubble's Law, published in work by physicist Edwin Hubble in 1929, which discerned that galaxies are moving away from Earth at a rate that accelerates proportionally with distance. Independent of Friedmann's work, and independent of Hubble's observations, physicist Georges Lemaître proposed that the universe emerged from a "primeval atom" in 1931, introducing the modern notion of the Big Bang.
The cosmos is an alternative name for the universe or its nature or order. Usage of the word cosmos implies viewing the universe as a complex and orderly system or entity.
Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons and nuclei. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis. After about 20 minutes, the universe had expanded and cooled to a point at which these high-energy collisions among nucleons ended, so only the fastest and simplest reactions occurred, leaving our universe containing hydrogen and helium. The rest is traces of other elements such as lithium and the hydrogen isotope deuterium. Nucleosynthesis in stars and their explosions later produced the variety of elements and isotopes that we have today, in a process called cosmic chemical evolution. The amounts of total mass in elements heavier than hydrogen and helium remains small, so that the universe still has approximately the same composition.
The fine-tuned universe is the hypothesis that, because "life as we know it" could not exist if the constants of nature – such as the electron charge, the gravitational constant and others – had been even slightly different, our universe is tuned specifically for life. In practice, this hypothesis is formulated in terms of dimensionless physical constants.
Lawrence Maxwell Krauss is a Canadian-American theoretical physicist and cosmologist who taught at Arizona State University (ASU), Yale University, and Case Western Reserve University. He founded ASU's Origins Project in 2008 to investigate fundamental questions about the universe and served as the project's director.
Atom: Journey Across the Subatomic Cosmos is a non-fiction book by Isaac Asimov. It was initially published on May 31, 1991, by Dutton Adult.
Physics World is the membership magazine of the Institute of Physics, one of the largest physical societies in the world. It is an international monthly magazine covering all areas of physics, pure and applied, and is aimed at physicists in research, industry, physics outreach, and education worldwide.
Cosmology is a branch of physics and metaphysics dealing with the nature of the universe, the cosmos. The term cosmology was first used in English in 1656 in Thomas Blount's Glossographia, and in 1731 taken up in Latin by German philosopher Christian Wolff in Cosmologia Generalis. Religious or mythological cosmology is a body of beliefs based on mythological, religious, and esoteric literature and traditions of creation myths and eschatology. In the science of astronomy, cosmology is concerned with the study of the chronology of the universe.
Big History is an academic discipline which examines history from the Big Bang to the present. Big History resists specialization, and searches for universal patterns or trends. It examines long time frames using a multidisciplinary approach based on combining numerous disciplines from science and the humanities, and explores human existence in the context of this bigger picture. It integrates studies of the cosmos, Earth, life, and humanity using empirical evidence to explore cause-and-effect relations, and is taught at universities and primary and secondary schools often using web-based interactive presentations.
The history of the Big Bang theory began with the Big Bang's development from observations and theoretical considerations. Much of the theoretical work in cosmology now involves extensions and refinements to the basic Big Bang model. The theory itself was originally formalised by Father Georges Lemaître in 1927. Hubble's law of the expansion of the universe provided foundational support for the theory.
The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
Cosmic Odyssey is a 2002 Canadian documentary television series about the cosmos, created by Avanti Pictures, narrated by William Shatner, and produced by Soapbox Entertainment for The Discovery Channel. In 2003, Schlessinger Media released the series in VHS video format. As of 2007, the series is syndicated on The Science Channel.
The American Institute of Physics (AIP) instituted their Science Writing Award to "promote effective science communication in print and broadcast media in order to improve the general public's appreciation of physics, astronomy, and allied science fields." The winner receives $3000, and an engraved Windsor chair. The award is given in three broad categories: 1) science writing, 2) work intended for children, and 3) work done in new media. The AIP stopped issuing awards to three categories: 1) work by a professional journalist 2) work by a scientist, and 3) broadcast media
The Symphony of Science is a music project created by Washington-based electronic musician John D. Boswell. The project seeks to "spread scientific knowledge and philosophy through musical remixes." Boswell uses pitch-corrected audio and video samples from television programs featuring popular educators and scientists. The audio and video clips are mixed into digital mashups and scored with Boswell's original compositions. Two of Boswell's music videos, "A Glorious Dawn" and "We are All Connected", feature appearances from Carl Sagan, Richard Feynman, Neil deGrasse Tyson, Bill Nye, and Stephen Hawking. The audio and video is sampled from popular science television shows including Cosmos, The Universe, The Eyes of Nye, The Elegant Universe, and Stephen Hawking's Universe.
The Grand Design is a popular-science book written by physicists Stephen Hawking and Leonard Mlodinow and published by Bantam Books in 2010. The book examines the history of scientific knowledge about the universe and explains eleven-dimensional M-theory. The authors of the book point out that a Unified Field Theory may not exist.
Adam Frank is an American physicist, astronomer, and writer. His scientific research has focused on computational astrophysics with an emphasis on star formation and late stages of stellar evolution. His work includes studies of exoplanet atmospheres and astrobiology. The latter include studies of the generic response of planets to the evolution of energy-intensive civilizations (exo-civilizations).
How It Began: A Time Traveler's Guide to the Universe is a non-fiction book by the astronomer Chris Impey that discusses the history of the universe, with chapters ranging from the proximate universe to within an iota of the Big Bang. It was published as a hardcover by W. W. Norton & Company in 2012 and as a paperback in 2013. It is actually the prequel to his 2010 book How it Ends: From You to the Universe, which talks about how everything, from individual humans, to the human species, to the Earth, and finally, the universe, might one day end in the future.
Beyond Star Trek: Physics from Alien Invasions to the End of Time is the fourth non-fiction book by the American theoretical physicist Lawrence M. Krauss. The book was initially published on November 7, 1997 by Basic Books and since then has appeared in five foreign editions. In his previous work, The Physics of Star Trek, Lawrence Krauss explained a number of ideas and concepts featured in the series; they may or may not exist in our universe. In this book, Krauss goes farther to discuss the realities of physics when it is applied to components from other sci-fi story lines.
Brief Answers to the Big Questions is a popular science book written by physicist Stephen Hawking, and published by Hodder & Stoughton (hardcover) and Bantam Books (paperback) on 16 October 2018. The book examines some of the universe's greatest mysteries, and promotes the view that science is very important in helping to solve problems on planet Earth. The publisher describes the book as "a selection of [Hawking's] most profound, accessible, and timely reflections from his personal archive", and is based on, according to a book reviewer, "half a million or so words" from his essays, lectures and keynote speeches.
