No Redshift from Distant Galaxies: Implications for Universe

In summary, if no distant galaxy showed any redshift or blueshift, it would support the steady state theory which suggests the universe is static and infinite. It would also align with Einstein's original theory of a static model with a cosmological constant cancelling gravity. However, we now know that Einstein was wrong on this and the cosmological constant may not have been a 'blunder' after all.

So what if no distant galaxy showed any redshift of blueshift? what would that mean?
What would this imply about the universe? What-if any –effects would this have on the Earth?

I figure this would support the steady state theory and that it was static and infinite.
anything else??
thanks

Your conclusion is probably right, but what is the point. The red shifts of galaxies has been observed and analysed for over 80 years.

According to the steady state theory space does also expand, but without an initial singularity (it makes use of a de-Sitter cosmological model).

No, it would support Einstein's original 'blunder' with the cosmological constant cancelling gravity (his static model). But we now know that Einstein was wrong on that one and he was (probably) wrong on declaring the cosmological constant a 'blunder' as well!:smile:
 

FAQ: No Redshift from Distant Galaxies: Implications for Universe

What is redshift and how does it relate to distant galaxies?

Redshift is a phenomenon in which the light from an object is shifted towards the red end of the electromagnetic spectrum. This occurs when an object is moving away from the observer. In the case of distant galaxies, redshift is used as a measure of their distance from Earth.

What are the implications of not observing redshift in distant galaxies?

The lack of redshift in distant galaxies could challenge our current understanding of the expanding universe. It could suggest that these galaxies are not moving away from us, which would contradict the widely accepted theory of the Big Bang and the expansion of the universe.

What methods were used to study the redshift of distant galaxies?

Scientists often use spectroscopy to study the redshift of distant galaxies. This involves analyzing the light spectrum of the galaxy and looking for specific patterns or shifts that indicate the presence of redshift.

Are there any alternative explanations for the lack of redshift in distant galaxies?

Some scientists have proposed alternative theories, such as the possibility of a static universe or the existence of a "tired light" effect, to explain the lack of redshift in distant galaxies. However, these theories have not been widely accepted and further research is needed to determine their validity.

How could this new discovery impact our understanding of the universe?

If confirmed by further research, the lack of redshift in distant galaxies could challenge the current model of the expanding universe and require a reevaluation of our understanding of the origins and evolution of the universe. It could also lead to the development of new theories and explanations for the observed data.
