Gravity Probe B Proves General Relativity Still Valid. The process of temporal becoming in my own consciousness smacks against the claims of B-theorists. Hartle provides a fluent and accessible introduction that uses a minimum of new mathematics and is illustrated with a wealth of exciting applications. Also, special relativity considers space-time to be a passive arena for events, but general relativity requires spacetime to be dynamic in the sense that changes in matter-energy can change the curvature of space-time itself. General relativity is said to have reintroduced absolute simultaneity into physics. But we also know that clock at B is moving with respect to the ground, and by the principles of special relativity must be running slower than C. Gravity Probe B has confirmed two of the most interesting effects predicted by Einstein's General Theory of Relativity. Using a “physics first” approach to the subject, renowned relativist James B. Indeed, Einstein himself needed help from professional mathematicians in formulating some of it, and well after general relativity was published (in 1915) some of the greatest mathematicians of the twentieth century (such as Kurt Gödel) . The GP-B satellite was launched in April 2004 and collected a year's worth of data to determine if predictions of Albert Einstein's General Theory of Relativity are correct. 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. NASA has just announced that Einstein's theory of gravity, also known as the General Theory of Relativity, has been verified in two ways by its Gravity Probe-B (GP-B) with astonishing accuracy [1]. Common sense, but for distant events occurring close enough in time to be in each other's absolute elsewhere, event A can occur before event B in one reference frame, but after B in another frame, and simultaneously with B in yet another frame. [B]eauty is a consequence of [general relativity and the Standard Model] being effective and approximate.
