What else can I help you with?
What helped scientist determine the age of the universe?
The redshift of the cosmic microwave background radiation
What do scientists believe provides evidence for the bid bang theory?
Scientists believe that several key pieces of evidence support the Big Bang theory, including the observed expansion of the universe, cosmic microwave background radiation, and the abundance of light elements like hydrogen and helium. The redshift of distant galaxies indicates that the universe is expanding, while the cosmic microwave background radiation is thought to be the afterglow of the initial explosion. Additionally, the proportions of light elements align with predictions made by Big Bang nucleosynthesis. Together, these observations provide strong support for the theory.
How does redshift connect to cosmic bakcground radiation?
Both are evidence in favor of Big Bang Cosmology (BBC). Hubble Redshift is easy to explain with BBC, not so easy (but possible) with alternatives. The existence, isotropy, and spectrum of the cosmic microwave background radiation is also easy to explain with BBC; but impossible to explain with any alternative. It's why BBC went from minority viewpoint amongst cosmologists to (pretty much) universal acceptance in a couple of decades.
What causes a cosmological redshift?
A redshift occurs when the wavelengths increase in objects by light or electromagnetic radiation levels in an object. In cosmological redshift also has to do with light; however, instead of an increase in wavelengths, there is an expansion of the universe.
If a star moves away from earth when all lines shift to where the waves are longer is what?
This phenomenon is known as redshift, which occurs when light from a moving object is shifted to longer wavelengths as it moves away from an observer. Redshift is a key piece of evidence supporting the theory of an expanding universe, as it indicates that galaxies are moving away from each other.
What does the red shift tell scientists?
The redshift tells scientists how fast a star or galaxy is moving away from us.
What helped scientist determine the age of the universe?
The redshift of the cosmic microwave background radiation
How do cosmic background radiation the chemical composition of the universe redshift of light and movement of galaxies support the theory of the Big Bang?
Redshift: The only reasonable explanation for the redshift is that most galaxies are moving away from us.As for the cosmic background radiation and the chemical composition, both of these closely match what is expected from the models about the Big Bang.

What is the name for the change in the star's spectrum when it moves away from earth?
That is called "redshift". The frequency of the radiation decreases.
What fact do all scientists believe provides evidence for the Big Bang theory Apex?
The fact that the universe is expanding is a key piece of evidence for the Big Bang theory. Observable redshift of distant galaxies, cosmic microwave background radiation, and the abundance of light elements like helium and hydrogen all support the idea that the universe began in a hot, dense state and has been expanding ever since.
In astrophysics terms when does redshift happen?
In astrophysical terms, redshift occurs when light or electromagnetic radiation increases in wavelength and shift to the red end of the spectrum. In other words colors seem more red than they are.

What does the redshift tell us about the universe?
Redshift is a phenomenon where light from distant galaxies appears redder than expected due to the expansion of the universe. It tells us that the universe is expanding and provides evidence for the Big Bang theory. By studying the redshift of galaxies, scientists can understand the rate of expansion and the age of the universe.
What causes a cosmological redshift?
A redshift occurs when the wavelengths increase in objects by light or electromagnetic radiation levels in an object. In cosmological redshift also has to do with light; however, instead of an increase in wavelengths, there is an expansion of the universe.
Discuss one theory that have been proposed about the origin tof the unverse.Provide at least one piece of evidence to complete this theory?
The main theory, believed to be true by most scientists, is the Big Bang theory. Evidence include the redshift from distant galaxies - the most likely explanation is the so-called cosmological redshift; as well as the cosmic background radiation, which closely matches the expectations from the theory; and the distribution of elements (and isotopes) in the Universe, which also closely matches what would be expected from the theory.
When was The Redshift created?
The Redshift was created on 2008-09-22.
