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

€�Our analysis of observations of galaxy clusters show[s] that the redshift of the light is proportionally offset in relation to the gravitational influence from the galaxy cluster's gravity. Jun 30, 2011 - “Equivalence of matter and energy, E = mc2 (and by implication, the ability of gravity-and matter generally-to "bend" light), the existence of "rest energy", and the basis of nuclear energy (the conversion of matter to energy by humans and in the cosmos).” (Wikipedia) These Introductory Comments are copyrighted: Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. It describes gravity as a geometric property of the fabric of spacetime. Mar 13, 2014 - General relativity (GR) is the theory that replaces Newton's version of gravitation, but at the end of the day it's still gravity, and it has the same strength that it always did. Dec 23, 2011 - If you ask a physicist to think of the Einstein equation, though, this is the one they'll think of. A physicist and historian of science. Sep 28, 2011 - It will be a while before we have follow-up experiments that could conceivably replicate these results, but it's interesting to see that another aspect of Einstein's work, the General Theory of Relativity, has received a new kind of confirmation, this time on a cosmological scale. Jun 4, 2013 - A decade after his paper on special relativity, Einstein published his general relativity that addressed accelerated reference frames and provided a new theory of gravity. Einstein's theory of general relativity is one of the crowning achievements of 20th century science. As discussed in the introduction, since the time of the ancient Greeks until well into the 20th century many scientists assumed that the universe was eternal. Special relativity had considered only constantly moving reference frames, so a .. But Einstein believed the Universe was static and so added a term that would provide some kind of . Introducing MIT Technology Review Insider. Jul 5, 2013 - These lectures notes by Gerard't Hooft introduce the basic concepts of GR. These equations predicted that the Universe would contract if gravity were too strong or expand if it were too weak. Mar 18, 2014 - IC: By exploiting a clever loophole in Einstein's general relativity theory, inflation produces an infinite number of galaxies by continuing forever, and an observer in one of these galaxies will view space and time differently, perceiving by producing the first-ever detection of Hawking/Unruh radiation (the process by which inflation's rapid doubling generates these gravitational waves), the BICEP2 team has found the first experimental evidence for quantum gravity.
