Which statement is INCORRECT about Cosmic Microwave Background radiation?
its temperature is uniform.
it consists of electromagnetic radiation that is a remnant of the Big Bang.
It appears uniformly across the universe.
it is evidence for the Little Bang Theory
The statement that is INCORRECT about Cosmic Microwave Background radiation is "it is evidence for the Little Bang Theory."
The statement "it is evidence for the Little Bang Theory" is incorrect. The correct theory is called the Big Bang Theory, and the Cosmic Microwave Background radiation is one of the pieces of evidence supporting this theory.
The incorrect statement about Cosmic Microwave Background (CMB) radiation is "it is evidence for the Little Bang Theory." The term "Little Bang Theory" is not a recognized scientific theory and does not exist in scientific literature or cosmology.
To determine this answer, we need to be familiar with the subject matter and have basic knowledge about the Big Bang theory and the properties of CMB radiation:
1. The Big Bang Theory is the leading explanation for the origin of the universe. It suggests that the universe started as an extremely hot and dense state about 13.8 billion years ago and has been expanding ever since.
2. CMB radiation is often considered the strongest evidence supporting the Big Bang theory. It is electromagnetic radiation that is a remnant of the very early stages of the universe, around 380,000 years after the Big Bang. As the universe expanded and cooled, this radiation stretched and cooled along with it, becoming the microwave radiation we observe today.
3. CMB radiation is highly isotropic, meaning it appears uniformly across the entire observable universe. Scientists have measured its temperature to be approximately 2.7 Kelvin (-270.45°C or -454.81°F) with only minor variations.
Based on this information, we can conclude that the statement "it is evidence for the Little Bang Theory" is incorrect.
