Cosmological relativity theories

Click For Summary
SUMMARY

The discussion centers on the implications of the proposed 'cosmological theory of relativity' in understanding the perception of time across vast cosmic distances. It highlights a paradox where observers in different galaxies perceive the timing of the Big Bang differently, with one galaxy potentially viewing itself as closer to the event than another. The theory suggests that light from distant galaxies takes significant time to reach us, necessitating a nuanced understanding of time in cosmological contexts. Key references include Carmeli's papers on Cosmological General Relativity (CGR) and the concept of 'spacevelocity'.

PREREQUISITES
  • Understanding of Cosmological General Relativity (CGR)
  • Familiarity with the concept of light travel time in astronomy
  • Knowledge of relativistic effects in cosmology
  • Basic grasp of Riemannian geometry as it applies to space-time
NEXT STEPS
  • Explore the implications of light travel time on cosmological observations
  • Research Carmeli's theories and their critiques in astrophysics
  • Investigate the concept of 'spacevelocity' in the context of relativistic physics
  • Utilize cosmological calculators to simulate light travel and time perception
USEFUL FOR

Astronomers, physicists, and cosmologists interested in the interplay of time and space in the universe, as well as anyone studying the implications of relativistic theories on cosmic observations.

If a galaxy is 1 billion light year far from us and if for us big bang
did happen 13 billion years ago then when it did happen for that galaxy ?

Pure guess will predict the answer 12 billion years, but what the observer on that galaxy will say about us ? will not he predict that we are close to big bang by one year ? just the opposite of what we predict here. Who is right ?

A new theory named 'cosmological theory of relativity' has been proposed.

Before saying that looking deep in space is identical to looking back in time make sure what time you are talking about.

It incorporates relativistic corrections and illustrates why light emitted by now distant objects took so long to reach us. I am familiar with Carmeli's papers. He is a bit of a maverick. That is not a bad thing. His papers are interesting, just not yet well supported by observational evidence.

astro-ph/0411180 says that in Cosmological General Relativity (CGR), gravitation is described by a curved four-dimensional Riemannian spacevelocity. i never heard before the term spacevelocity, and is not defined in the paper. Probably is an idea of Carmeli coming from previous papers
 
Has there been any progress with these theories over the past few years?
