General relativity from A to B Robert Geroch
Publisher: U.Chicago

"The space-time around Earth appears to be distorted just as general relativity predicts," says Stanford University physicist Francis Everitt, principal investigator of the Gravity Probe B mission. Shapiro time delays are one of the four tests of general relativity possible in the solar system. This problem is actually one assigned in the undergraduate general relativity course I took in the spring 2008. Using a “physics first” approach to the subject, renowned relativist James B. On Friday, I received an irritated message from Mel B. To be sure, the Gravity Probe B experiment is a fantastic achievement that offers spectacular evidence in support of two distinct predictions of the general theory of relativity. Note that Einstein explicitly used the equation c'=c(1+gh/c^2) in the period 1907-1915, then, in the final version of general relativity, replaced it with c'=c(1+2gh/c^2). Hartle's book Gravity: An Introduction to Einstein's General Relativity, chapter 6, problem 9. NASA's long term Gravity Probe-B mission has proven that Einstein's general relativity is, once again, accurate. Instead, let me mention that we're probably victims of some bad habits and ultimately invalid lore related to the way how we think about certain issues in general relativity. Astronomers Title: A Shapiro delay detection in the binary system hosting the millisecond pulsar PSRJ1910-5959A Authors: A. Seems very silly that people often cite the size of Earth/human beings in relation to the universe as a measure of each human's 'insignificance'. General relativity is composed of the equations that are locally valid, .. If gravity did not affect space and time, Gravity Probe B's gyroscopes would point in the same direction forever while in orbit. Gravity Probe B illustration (Stanford Univ.) A NASA mission more than half a century in the making has confirmed two key predictions of Einstein's theory of general relativity, project officials said Wednesday. The aim of this groundbreaking new book is to bring general relativity into the undergraduate curriculum and make this fundamental theory accessible to all physics majors. Hartle provides a fluent and accessible introduction that uses a minimum of new mathematics and is illustrated with a wealth of exciting applications. Who had read articles in the Guardian claiming that Eric Weinstein found a theory of Maldacena, Susskind: any entanglement is a wormhole of a sort.
