 Summary

Gravity Probe B (GPB) is a NASA physics mission to experimentally investigate Einstein’s 1916 general theory of relativity—his theory of gravity. GPB uses four spherical gyroscopes and a telescope, housed in a satelliteorbiting 642 km (400 mi) above the Earth, to measure, with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity: 1) the geodetic effect—the amount by which the Earth warps the localspacetime in which it resides; and 2) the framedragging effect—the amount by which the rotating Earth drags its local spacetime around with it. GPB tests these two effects by precisely measuring the precession (displacement)angles of the spin axes of the four gyros over the course of a year and comparing these experimental results with predictions from Einstein’s theory.

 Summary

Gravity Probe B (GPB) is a NASA physics mission to experimentally investigate Einstein’s 1916 general theory of relativity—his theory of gravity. GPB uses four spherical gyroscopes and a telescope, housed in a satelliteorbiting 642 km (400 mi) above the Earth, to measure, with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity: 1) the geodetic effect—the amount by which the Earth warps the localspacetime in which it resides; and 2) the framedragging effect—the amount by which the rotating Earth drags its local spacetime around with it. GPB tests these two effects by precisely measuring the precession (displacement)angles of the spin axes of the four gyros over the course of a year and comparing these experimental results with predictions from Einstein’s theory.

Gravity Probe B (GPB) is a NASA physics mission to experimentally investigate Einstein’s 1916 general theory of relativity—his theory of gravity. GPB uses four spherical gyroscopes and a telescope, housed in a satelliteorbiting 642 km (400 mi) above the Earth, to measure, with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity: 1) the geodetic effect—the amount by which the Earth warps the localspacetime in which it resides; and 2) the framedragging effect—the amount by which the rotating Earth drags its local spacetime around with it. GPB tests these two effects by precisely measuring the precession (displacement)angles of the spin axes of the four gyros over the course of a year and comparing these experimental results with predictions from Einstein’s theory.

Gravity Probe B (GPB) is a NASA physics mission to experimentally investigate Einstein’s 1916 general theory of relativity—his theory of gravity. GPB uses four spherical gyroscopes and a telescope, housed in a satelliteorbiting 642 km (400 mi) above the Earth, to measure, with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity: 1) the geodetic effect—the amount by which the Earth warps the localspacetime in which it resides; and 2) the framedragging effect—the amount by which the rotating Earth drags its local spacetime around with it. GPB tests these two effects by precisely measuring the precession (displacement)angles of the spin axes of the four gyros over the course of a year and comparing these experimental results with predictions from Einstein’s theory.

Gravity Probe B (GPB) is a NASA physics mission to experimentally investigate Einstein’s 1916 general theory of relativity—his theory of gravity. GPB uses four spherical gyroscopes and a telescope, housed in a satelliteorbiting 642 km (400 mi) above the Earth, to measure, with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity: 1) the geodetic effect—the amount by which the Earth warps the localspacetime in which it resides; and 2) the framedragging effect—the amount by which the rotating Earth drags its local spacetime around with it. GPB tests these two effects by precisely measuring the precession (displacement)angles of the spin axes of the four gyros over the course of a year and comparing these experimental results with predictions from Einstein’s theory.

 Summary

Gravity Probe B (GPB) is a NASA physics mission to experimentally investigate Einstein’s 1916 general theory of relativity—his theory of gravity. GPB uses four spherical gyroscopes and a telescope, housed in a satelliteorbiting 642 km (400 mi) above the Earth, to measure, with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity: 1) the geodetic effect—the amount by which the Earth warps the localspacetime in which it resides; and 2) the framedragging effect—the amount by which the rotating Earth drags its local spacetime around with it. GPB tests these two effects by precisely measuring the precession (displacement)angles of the spin axes of the four gyros over the course of a year and comparing these experimental results with predictions from Einstein’s theory.
