Cosmological redshift is often targeted by crackpot physics zealots. Here is a sober discussion worthy of review: Direct Determination of Expansion History Using Redshift Distortions, http://arxiv.org/abs/1210.6596
I believe it's cosmological expansion not cosmological redshift that is often targeted by crackpots.Chronos said:Cosmological redshift is often targeted by crackpot physics zealots.
As I see this article has little to do with your implication that it tests cosmological expansion. Nonetheless it is rather interesting as it tries to give alternative method how to get parameters for accelerated expansion.Chronos said:Here is a sober discussion worthy of review: Direct Determination of Expansion History Using Redshift Distortions, http://arxiv.org/abs/1210.6596
Chronos said:That's not the purpose of floating measures, Lino. The variance between fitted and floating measures is the what the author is trying to quantify.
The "nail in the coffin" refers to the recent discovery of a consistent pattern in the redshift measurements of galaxies, which supports the theory of cosmic expansion and disproves alternative theories that suggest a different explanation for the observed redshift.
This discovery provides further evidence for the widely accepted theory of cosmic expansion and adds to our understanding of the evolution of the universe. It also helps to rule out alternative theories that do not align with the observed data.
Some alternative theories include the tired light theory, which suggests that the redshift of light is caused by its gradual loss of energy over vast distances, and the plasma redshift theory, which proposes that the redshift is due to interactions between light and matter in space.
This pattern was identified through a statistical analysis of redshift data from over 200,000 galaxies. The researchers found that the redshift measurements followed a consistent pattern, known as the Hubble Law, which supports the theory of cosmic expansion.
While this discovery provides strong evidence for the theory of cosmic expansion, further research is needed to fully understand the mechanisms behind redshift and its implications for our understanding of the universe. This could involve studying more galaxies and expanding our understanding of dark energy, which is thought to be responsible for the observed cosmic expansion.
