Gravitational redshift experiment

The Pound–Rebka experiment of 1959 measured the gravitational redshift in spectral lines using a terrestrial 57 Fe gamma source over a vertical height of 22.5 metres.

WebGravitational redshift experiments are tests of conservation of energy in a gravitational potential. A photon lower in a gravitational potential expends energy to climb out, and this energy cost is seen as a redshift.

In the years subsequent to the series of measurements performed by the Pound lab, various tests using other technologies established the validity of gravitational redshift/time dilation with increasing precision. A notable example was the 1976 Gravity Probe A experiment, which used a space-borne hydrogen maser to increase the accuracy of the measurement to about 0.01%.
