Steven Weinberg, a theoretical physicist who discovered that two of the universe's forces are really the same, for which he was awarded the Nobel Prize, and who helped lay the foundation for the development of the Standard Model, a theory that classifies all known elementary particles in the universe, making it one of .
According to NASA, the definition of cosmology is "the scientific study of the large scale properties of the universe as a whole." Cosmologists puzzle over exotic concepts like string theory, dark matter and dark energy and whether there is one universe or many (sometimes called the multiverse)..
Greek philosophers Aristarchus of Samos, Aristotle, and Ptolemy proposed different cosmological theories.
The geocentric Ptolemaic system was the prevailing theory until the 16th century when Nicolaus Copernicus, and subsequently Johannes Kepler and Galileo Galilei, proposed a heliocentric system..
The origins of today's cosmology began with the observation in the early 1500s by Nicolaus Copernicus that the Earth revolves around the Sun.
The next step was the discovery in the late 1600s by Isaac Newton that objects in space behaved according to the same laws of physics as objects on Earth..
Cosmology (2008) is a textbook about cosmology by American physicist Steven Weinberg.
The textbook is intended for final-year physics undergraduates or first-year graduate students.
The book is a successor to Weinberg's 1972 textbook Gravitation and Cosmology..
In the 2006 book "The God Delusion", Richard Dawkins identified Steven Weinberg as an atheist
Then in 2008, Weinberg was asked whether he really was atheistic
"Yes, I don't believe in God," he replied, " but I don't make a religion out of not believing in GodIn it, the weak and electromagnetic interactions already unified by the work of Weinberg, Salam and Glashow, are made consistent with a theory of the strong interactions between quarks, in one overarching theory
In 1973, Weinberg proposed a modification of the Standard Model that did not contain that model's fundamental Higgs boson
