Re: Gravitational red-shifting in the biggest star. What are the real colors?

QUOTE FROM WIKI;
In astronomy, the magnitude of a gravitational redshift is often
expressed as the velocity that would create an equivalent shift through
the relativistic Doppler effect. In such units, the 2 ppm sunlight
redshift corresponds to a 633 m/s receding velocity, roughly of the same
magnitude as convective motions in the Sun, thus complicating the
measurement.
QUOTE MORE BULL SHIT
In astronomical objects with strong gravitational fields the redshift
can be much greater; for example, light from the surface of a white
dwarf is gravitationally redshifted on average by around (50 km/s)/c
(around 170 ppm).[12]
Observing the gravitational redshift in the Solar System is one of the
classical tests of general relativity.[13] Measuring the gravitational
redshift to high precision with atomic clocks can serve as a test of
Lorentz symmetry and guide searches for dark matter.

The first accurate measurement of the gravitational redshift of a white
dwarf was done by Popper in 1954, measuring a 21 km/s gravitational
redshift of 40 Eridani B.[16] The redshift of Sirius B was finally
measured by Greenstein et al. in 1971, obtaining the value for the
gravitational redshift of 89±16 km/s,

In 2018, the star S2 made its closest approach to Sgr A*, the 4-million
solar mass supermassive black hole at the centre of the Milky Way,
reaching 7650 km/s or about 2.5% of the speed of light while passing the
black hole at a distance of just 120 AU, or 1400 Schwarzschild radii.

In 2021, Mediavilla (IAC, Spain) & Jiménez-Vicente (UGR, Spain) were
able to use measurements of the gravitational redshift in quasars up to
cosmological redshift of z ≈ 3 to confirm the predictions of Einstein's
equivalence principle and the lack of cosmological evolution within
13%.[28]
---------------------------------------------------
THEN, WITH z = 6,842,736, THE LIGHT OF UY Scuti WOULD BE IMPOSSIBLE TO
REACH EARTH, BECAUSE ITS DOPPLER EQUIVALENT RECESSION SPEED SHOULD BE
(ACCORDING TO CALCULATIONS) WOULD BE MUCH GREATER THAN c.
EVEN IF IT'S 100,000 LESS MASSIVE THAN THE PRIOR CALCULATIONS,z WOULD BE
z = 684.27
Yet, it's visible since 1860.
What is wrong (Wiki and the GR theory?).
