<title>Stiati ca experimentul Pound-Rebka poate sa explice altfel decat teoria lui Hubble redshift-ul stelelor?</title>

<description>&lt;p&gt;Am fost perfect de acord cu comentariul lui Pav din 21 februarie 2021 (la intrebarea&amp;nbsp;&lt;a rel=&quot;nofollow&quot; href=&quot;https://scientia.ro/qa/19234/deplasarea-spre-rosu-a-spectrului-de-la-stelele-indepartate-este-cauzata-de-indepartarea-stelelor-una-de-alta&quot;&gt;Deplasarea spre rosu a spectrului de la stelele indepartate este cauzata de indepartarea stelelor una de alta? - Scientia QA&lt;/a&gt;&amp;nbsp;) Pe forum.scientia.ro este un utilizator (calahan) care are din cand in cand postari interesante si de acolo mi-a venit ideea sa caut ce-i experimentul Pound-Rebka:&lt;a rel=&quot;nofollow&quot; href=&quot;https://en.wikipedia.org/wiki/Pound%E2%80%93Rebka_experiment&quot;&gt;Pound–Rebka experiment - Wikipedia&lt;/a&gt;&amp;nbsp;: (1959) &quot;...&lt;span style=&quot;color:rgb(32, 33, 34); font-family:sans-serif; font-size:14px&quot;&gt;In the Pound–Rebka experiment, the emitter was placed at the top of a tower with the receiver at the bottom.&amp;nbsp;&lt;/span&gt;&lt;a rel=&quot;nofollow&quot; href=&quot;https://en.wikipedia.org/wiki/General_relativity&quot;&gt;General relativity&lt;/a&gt;&lt;span style=&quot;color:rgb(32, 33, 34); font-family:sans-serif; font-size:14px&quot;&gt;&amp;nbsp;predicts that the gravitational field of the Earth will cause a photon emitted downwards (towards the Earth) to be blueshifted (i.e. its frequency will increase)...&quot; iar la iesirea din campul gravitational apare redshift-ul. Fara sa se cunoasca masa stelelor din Legea lui Hubble este greu sa se calculeze redshift-ul conform experimentului Pound-Rebka.&lt;/span&gt;&lt;/p&gt;</description>
