Observation of the red shift of galaxies suggest that the universe is what?
Expanding Or that the light is exiting a gravity hole (star).
What determines galaxy motion and distance?
Galaxy motion and distance are determined by the expansion of the universe, influenced by the distribution of matter and dark energy. The collective gravitational forces between galaxies also play a role in their motion and organization within the universe. Measurements of redshift and luminosity distance are used to determine the distances to galaxies in the cosmos.
What is the red shift of hydrogen?
The red shift depends on the relative motion of the emitting source and receiving detector. Hydrogen per se has no red shift. There is hydrogen with great red shift (in stars in galaxies far away that are moving rapidly away from us).
What does the red shift of the galaxies tell us about their motion with respect to the Earth?
Less than you'd think. At extreme distances, the red-shift is caused by metric expansion more than by motion. So to be able to gauge the speed of an object relative to you, you'd first have to determine the pseudo-speed caused by metric expansion.
An observation of the red shift of galaxies suggest that the universe is?
expanding. This expansion causes the wavelengths of light from galaxies to stretch as they move away from us, resulting in a red shift. This observation supports the theory of the Big Bang, suggesting the universe began from a single point and has been expanding ever since.

What is the Doppler shift of galaxies?
It shows how galaxies are moving in relation to Earth.

What is the difference between the cosmological and Doppler red shift?
Red shift is the change in the spectra of galaxies towards being more red than we would expect them to be. Doppler Shift results from galaxies being in motion away from us. Thus, the large Andromeda Galaxy has a blue shift, because it and our Milky Way Galaxy are being pulled towards each other due to gravity. Cosmological Shift results from the space between us and other galaxies growing larger over time, even though neither they nor our Milky Way Galaxy are in motion relative to one another.
Do galaxies shift near or far away from earth?
Most galaxies have a red shift away from us - meaning they are moving away from us. However, the Andromeda galaxy has a blue shift, which means it is moving towards us. In about 2.5 billion years time, the two galaxies will merge.
Does red shift have anything to do with irregular galaxies?
NoRed shift is the Doppler effect as it applies to the light from receding galaxies and stars.As the name suggests, "irregular" galaxies have no specific form, and so the group contains a very diverse selection of objects.
What galaxies have a blue shift?
There are about a 100 known blue shifted galaxies. The most well known, is the Andromeda Galaxy.
What is red shift inti?
When galaxies move away from us, the waves of light stretch out- ie, they become redder. The greater the red shift, the faster the galaxies are moving away from us.
What observation of the light from galaxies shows that nearly all galaxies are moving away from us?
The Red Shift or Doppler effect
