Pound-rebka
Web18 Feb 2024 · "They [Pound and Rebka] sent gamma rays up a 20m tower and measured the redshift (that is, the decrease in frequency) at the top. This was a notable feat indeed, considering that they were able to measure a frequency shift of gh/c^2 (which is only a few parts in 10^15) to within 1% accuracy." WebPound-Rebka実験 は、 ガンマ線 が塔の上部から放出され、塔の下部にある受信機によって測定される実験でし た。 実験の目的は、 光子 が重力源(地球)に向かって移動するときにエネルギーを獲得すること を示すことによって、 アルバートアインシュタイン の 一般相対性理論をテストすることでした。 これは、1959年に ロバートパウンド と彼の大学院生 …

WebThe Pound-Rebka Experiment The Pound-Rebka experiment is a pure quantum mechanical demonstration of the gravitational expansion of mass, space and time. It is a precise set of measurements of the force and motion of gravity and their interactions with the momentum of photons. This experiment is a simple mechanical process for the measurement of

Web5 Sep 2024 · We describe an experiment which is very similar to the famous Pound-Rebka experiment, which used the Mössbauer effect to verify for the first time Einstein’s prediction for the curvature of time, but which employs Mossbauer emitters and absorbers with nonzero spin. We present a specific, realistic proposal for such an experiment.
