Gravity: an introduction to Einstein's General Relativity James B. Hartle
Publisher: Benjamin Cummings

Dec 23, 2011 - If you ask a physicist to think of the Einstein equation, though, this is the one they'll think of. The presence of mass warps space and time, The fact that gravity acts by changing the geometry of space and time sets it apart from all other forces. The test was done by astronomers in the US and Switzerland The cosmological constant is a term introduced to represent the energy of empty space and prevent the universe from collapsing due to self gravity. Under general relativity there is no ether or constant frame of reference, and gravity is reduced simply to an effect of curving space-time. Mar 17, 2014 - Statements by Gravity Probe-B researchers that the region around Earth resembles a “space-time vortex” lend credibility to the premise of this paper that potential vortex flow and gravity are related. Mar 10, 2010 - Einstein's general theory of relativity has been tested for the first time over distances nearly as large as the universe itself – and has, in the process, trumped most other alternative theories of gravity. Sep 29, 2010 - Einstein showed that the presence of gravity affects geometry by warping space and time. Mar 19, 2012 - The most famous document to be made available online is the original 1916 manuscript for Einstein's general theory of relativity. Authors: Nojiri, S Some people have proposed that Einstein's theory of general relativity could be modified to explain dark energy. On top of that, I am eager to learn, where physics and every day wisdom come apart, and your article indeed makes a very good introduction. While it is true that one needs some mathematical machinery to really master these theories, Egdall does a great job in That said, I do consider the book well-written, entertaining and a useful introduction to the ideas of relativity for the lay person. Albert Einstein introduced the first analogue model for General Relativity that describes space-time as a membrane upon which objects move along geodesics. Aug 27, 2012 - The most accurate theory of gravity is Einstein's General Theory of Relativity. Jun 6, 2008 - Article Title: Introduction to modified gravity and gravitational alternative for dark energy. In fact our best theories of particles assume that .. Part II introduces us to general relativity which is the most accurate theory of gravity know to science. The general relativity theory replaces that most basic and intuitive of concepts from Enlightenment physics, Newtonian gravity, with the Einstein fi eld equation. May 8, 2014 - It was during the war years that Einstein introduced his theory of general relativity, more radical than his special relativity. Anonymous says: October 10, 2013 at 11:31 pm. Both special and general relativity have a reputation for being very complicated theories to understand.
