Redshift does not expand the universe. Redshift is a physical quantity that is used to describe the expansion of the universe. The current time has a redshift of zero. at redshift 1, the universe was half the size it is now. At redshift 2, the universe was 1/3 the size it is now, and so on. if redshift is z, then

(size of universe at redshift z)/(current size of universe)= 1/(z+1)

Yes, redshift is the phenomenon where light from objects moving away from us appears to have a longer wavelength, shifting towards the red end of the spectrum. This is a key piece of evidence supporting the expansion of the universe, as it indicates that galaxies are moving away from each other.

In the universe what is the red shift?

The alterations to the electromagnetic spectrum caused by the expansion of the universe.


How does red shift support the steady state theory?

Red shift does not support the steady state theory. The red shift of distant galaxies suggests that the universe is expanding, which contradicts the steady state theory that posits a constant, unchanging universe. The red shift is consistent with the Big Bang theory, which states that the universe began as a singularity and has been expanding ever since.


How is the universe changing by red shift?

Redshift in the universe occurs as objects move away from one another, expanding the universe. This indicates that the universe is still expanding, consistent with the Big Bang theory. The rate of this expansion, known as the Hubble constant, provides insight into the age and future of the universe.


Why the red shift in light from distant galaxies indicate that the universe is expanding?

Red shift is observed in the spectrum of light from an object when it is moving away from the observer. Most astronomical objects display a red shift in their light. Also, the red shift is greater for objects which are further away. For this to happen - in all directions, the universe must be expanding.


What model of universe creation is supported by the red shift?

The model of universe creation supported by the red shift is the Big Bang theory. Red shift is the observation that galaxies are moving away from us, indicating that the universe is expanding. This expansion suggests that the universe originated from a hot, dense state, which is a key aspect of the Big Bang theory.

Why are red shift and blue shift effects useful in the study of the universe?

Red shift means that other objects in the universe are moving away and blue shift means they are moving toward you. This helps to tell where these objects came from, and this knowledge helps predict where they are going to.

What theory does red shift support?

Red shift supports the theory of the expanding universe proposed by Edwin Hubble. The observed red shift in the spectra of distant galaxies indicates that they are moving away from us, providing evidence for the idea that the universe is continuously growing and expanding.


How does the astronomers know that the universe is expanding?

According to calculations (related to the General Theory of Relativity), the Universe can't remain static forever. Eventually, it must either expand or contract. According to observations, it is expanding. That is, in general, the farther a galaxy is away from us the faster it moves away. This can be observed by the red-shift of the light of such a galaxy - and the only reasonable explanation for this red-shift is the Doppler effect.


Do the universe expand?

Yes, the universe expand.
