New Theories / Re: What is the real meaning of the most-distant-quasar/galaxy?
« on: 24/05/2022 12:46:21 »Recession velocity and cosmological redshift is based on the idea of expansion of space:That's nice, but did you understand that this statement, "If we see a galaxy with a redshift of 11, then this galaxy is moving away from us at 11c" is incorrect?
https://en.m.wikipedia.org/wiki/Recessional_velocity
Recessional velocity is the rate at which an extragalactic astronomical object recedes (becomes more distant) from an observer as a result of the expansion of the universe.[1] It can be measured by observing the wavelength shifts of spectral lines emitted by the object, known as the object's cosmological redshift.
The expansion of the universe is integrated part of the BBT.
I consider that redshift is all about linear velocity stamp that comes with the far end galaxy light
We can still see it due to relative velocity (with ref to the observer as explained by einstein)
Never the less, even without filtering this request of the BBT we can go on.
If all the galaxies that we observe are moving slower than the speed of lightAgain, if we can observe the galaxy then obviously its recession velocity is less than c.
then why do they come with so dramatic change in their integrated redshift?What do you mean by that?
