Yes, cosmology has had excellent success in building up a consistent picture of the history of the universe based on established science and observations.
If the word of God gives a true picture of the future and start of the universe, what science has built up is a crock. But as I point out betimes, science is based only on beliefs when it comes to origins, so what we have is another religion that opposes Scripture that was set up.
No, it is not circular. It is a measurement. Measurement of the CMB gives us a 'distance' -- how far the light has redshifted from when it was produced and when it was measured. Measurement of the Hubble constant tells us a rate or speed -- how fast the redshift changes.
"The Hubble Constant can be stated as a simple mathematical expression, Ho = v/d, where v is the galaxy's radial outward velocity (in other words,
motion along our line-of-sight), d is the galaxy's distance from earth, and Hois the current value of the Hubble Constant.
However, obtaining a true value for Ho is very complicated. Astronomers need two measurements. First, spectroscopic observations reveal the galaxy's redshift, indicating its radial velocity. The second measurement, the most difficult value to determine, is the galaxy's precise distance from earth.
Reliable "distance indicators," such as variable stars and supernovae, must be found in galaxies. The value of Ho itself must be cautiously
derived from a sample of galaxies that are far enough away that motions due to local gravitational influences are negligibly small."
Hubble Constant
So the view from the fishbowl is our line of sight. Any time in the calculation is absolutely destroyed unless you can prove that time even exists out there AS it does here! Boom. Then they NEED the distances derived from cepheid variables etc, and these cannot be defended in any way. The cosmic distance ladder uses time in the fishbowl to set the clocks for the universe. Parallax uses fishbowl time and space. The Hubble constant is nothing more than smoke and mirrors and circular reasoning and religion. Truly.
If at 5 pm, you complete a journey of 80 miles travelling at an average speed of 40 miles per hour, at what time did your journey begin?
Travelling in the fishbowl? Ha.
The age of the universe is measured, not 'claimed' because 'we need it to be so'.
Measured WITH fishbowl time, and BY fishbowl time!
They measure themselves and their fishbowl BY comparing themselves and their fishbowl WITH themselves and their fishbowl!!!!!!!!!!!
