Big Bang Theory - Scientific Concepts SeriesBarry Bingham
The big-bang model is based on two assumptions. The first is thatAlbert Einstein’sgeneral theory of relativitycorrectly describes thegravitationalinteraction of allmatter. The second assumption, called thecosmological principle, states that an observer’s view of the universe depends neither on the ...
The Big Bang Theory is the prevailing cosmological model explaining the origin of the universe. It posits that approximately 13.8 billion years ago, the universe began as an infinitely hot and dense state, expanding rapidly. Click for PDF and Google Slid
Physics breaks down at this level because there is no current theory of quantum gravity. However, at the moment of the Big Bang none of the four forces exist because there are no particles, including quarks, bosons, and leptons (see Section 1-16.0 of Chapter 1, "Philosophy of Science")....
Georges Lemaître was a Belgian astronomer and cosmologist who formulated the modern big-bang theory, which holds that the universe began in a cataclysmic explosion of a small, primeval “super-atom.” A civil engineer, Lemaître served as an artille

This graphic shows a timeline of the universe based on the Big Bang theory and inflation models. (Image credit: NASA / WMAP Science Team) However, since then gravitational waves have not only been confirmed to exist, they have been observed multiple times. These waves, which are not B-mod...
Big Bang Nucleosynthesis refers to the era in the early universe when nucleons combined to form light nuclei, such as deuterium, helium, and lithium, as the primordial plasma cooled down. This process depended on the rates of electromagnetic, weak, and strong interactions, as well as the expan...

One of the great mysteries of our universe, and a weakness of the Big Bang theory, is that matter, not antimatter, totally makes up our universe. According to the Big Bang theory, there should be equal amounts of matter and …Are
