New measurements of the solar spectrum verify Einstein’s theory of General Relativity
An international team of researchers led by the Instituto de AstrofĂ­sica de Canarias (IAC) has measured, with unprecedented accuracy, the gravitational redshift of the Sun, a change in frequency of the lines in the solar spectrum which is produced when the light escapes from the gravitational field of the Sun on its way to Earth. This work, which verifies one of the predictions of Einstein’s General Relativity, is to be published in the journal Astronomy & Astrophysics.
