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

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'. 2 ,” General Relativity and Gravitation, vol. The rotation of the Earth affects the movement of spacetime itself. Odintsov, “Where new gravitational physics comes fromml: M-theory?” Physics Letters B, vol. 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. A gravity probe whose origins date to the era before human spaceflight has finally proved general relativity right, according to NASA. 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. Has finally proved general relativity right, according to NASA. They developed a general scheme for cosmological reconstruction of modified gravity in terms of red-shift without using an auxiliary scalar in intermediate calculations. The Gravity Probe-B measured the geodetic effect, the amount that Earth warps the space and time in which it sits, and frame-dragging, or the extent that Earth's rotation churns spacetime around with it.
