Another solution of the gravitational redshift
is obtained with general relativity using the Schwarzschild metric.
The newly retrieved global speed of light c downstairs in the equivalence principle now has its consequences: all transversal lengths downstairs which at first sight look unchanged from above are actually increased by the gravitational redshift
factor relative to the tip.
he phenomenon is often called the gravitational redshift
because the oscillations of light waves slow down or become redder when tugged by gravity.
In the case of MCG-6-30-15, the gravitational redshift
is so extreme, says Fabian, that most of the emission must be coming from the gas and dust extremely close to the black hole.
Several follow-up articles verify its application to galaxies without requiring 'dark matter' for gravitational lensing by the galaxy quantization states , the quantization state of baryonic mass in clusters of galaxies , and how the cosmological redshift is interpreted as a gravitational redshift
that agrees with the accelerated expansion of the Universe .
Calculating the work done by the mass-radiation interaction on a photon, we derived the Einsteinian gravitational redshift
the bending of light by a massive body and of gravitational redshift
, have subsequently become part of the three benchmark tests for a model of gravitation.
21) also confirms the use of the constant h in the expression for gravitational redshift
This leads to an expression for gravitational redshift
An expression for gravitational redshift
is derived by accepting the local validity of special relativity at all points in space.
Calculating the work done by the mass-radiation interaction on a photon, we can derive the Einsteinian gravitational redshift
The observed redshift from distant sources can be interpreted as (1) a velocity redshift called the Doppler Effect, (2) a cosmological redshift in which space itself is expanding during the transit time of the photons, and/or (3) a gravitational redshift
as introduced by the General Theory of Relativity (GTR).
