CMB results cause the contradiction of big bang theory

In summary, the wavelength of light does not change in galaxies because the space of the galaxies does not expand. This is contradictory to the observed result, leading some to believe the big bang theory is wrong. However, the theory does not state that light must redshift by the same amount everywhere in our expanding universe.

- The wavelength of light doesn't change at all in the galaxies because the space of the galaxies doesn't expand.
- The wavelength of light should be different when it passes through the galaxy or not. However, this is contradictory to the observed result. So, the big bang theory is wrong.

Please give a specific reference for what experimental results you are referring to here.

No, your understanding of what the theory actually says is wrong. The theory does not say that light has to redshift by exactly the same amount everywhere in our expanding universe.

@Jinsuk Kim I asked for a reference--a textbook or peer-reviewed paper, not a personal theory from you. I have deleted your post and issued a warning, and this thread is closed. I strongly suggest that you take some time to learn what the big bang model actually says before posting again. Your posts indicate that you do not have a good understanding of it now.
 

What is the CMB and how does it relate to the big bang theory?

The CMB (Cosmic Microwave Background) is a form of radiation that permeates the entire universe. It is considered one of the strongest pieces of evidence for the big bang theory, as it is the leftover radiation from the hot, dense early universe.

What do the latest CMB results show that contradicts the big bang theory?

The latest CMB results show that the universe may be expanding faster than previously thought, which contradicts the current model of the big bang theory. This is known as the "Hubble tension" and has caused confusion and debate among scientists.

How are scientists trying to resolve this contradiction?

Scientists are currently exploring various explanations for the Hubble tension, such as the presence of unknown dark energy or modifications to the fundamental laws of physics. They are also conducting more precise measurements of the CMB and other cosmological data to gather more evidence.

Could the CMB results be wrong or misleading?

While it is always possible for scientific data to have errors or be interpreted incorrectly, the CMB results have been confirmed by multiple independent experiments. However, as with any scientific discovery, it is important for scientists to continue to question and test the results to ensure their accuracy.

What would be the implications if the big bang theory was proven to be incorrect?

If the big bang theory was proven incorrect, it would have significant implications for our understanding of the universe and its origins. It would require a major shift in scientific thinking and could potentially lead to new theories and models of the universe. However, at this point, the big bang theory remains the most widely accepted explanation for the origins of the universe.
