The expansion of space in all parts of our Universe.

When a group of photons leave an object (like a super-nova in a distant galaxy), they have a certain wavelength, and a certain distance between the first photons from that super-nova and the last such photons.

During their travel, the expansion of space causes the wavelength of the photons to increase (even if they interact with no matter whatsover in their travels), as well as the distance between the first photons to leave and the last photons to leave.

If these photons travel for enough time (say, a few 100 million to a few billion years) before they reach a detector on our Earth, the increase in wavelength AND the distance between the first and last photons becomes measurable. The photons have a wavelength longer than they "should" have, and the time between the first photons to arrive and the last to arrive will increase. The increase in wavelength, as well as the increase in time for the super-nova to last, will be as predicted by Hubble's Law.

Explain the movement and location of objects in the universe or their composition e g red shift blue shift line spectra?

The universe is expanding, as a result both of the Big Bang (some thirteen and a half billion years ago) and also what appears to be pressure exerted by what is known as dark energy (which is to say, some kind of energy which we have a great deal of difficulty in directly observing). Because of this expansion, distant objects (beyond our local galactic cluster) are moving away from us, and the more distant they are, the faster they are moving away. This receding motion creates a red shift (that is, a shift to longer wavelengths) in their spectra, known as a Doppler shift. If they were approaching rather than receding, the shift would be toward the blue (shorter wavelengths).


What determines galaxy motion and distance?

One of the most reliable methods employed presently is using Hubbles Laws and Constant, utilizing the red shift. RED SHIFT A+LS (:


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 red shift show?

The red shift shows the velocity with which an object is moving away from the earth. The red shift of an object is correlated to its distance from the earth and so it is also a measure of the distance.


How does red-shift support the steady state theory?

Red shift does not support the steady state theory.

What is the shift in the light of a galaxy toward the red wavelength called?

This phenomenon is called red shift.


What creates the phenomeon known as red shift?

Two things can cause red-shift:- The rapid motion of an object away from the observer. This is known as the Doppler-effect.- Expansion of space between the object and the observer.


What is important about the Hubble telescope's discovery that there is a red shift in the spectra of galaxies?

The Hubble telescope did not discover that there is a red shift in the spectra of Galaxies. The telescope is named after the American astronomer, Edwin Hubble, who discovered the phenomenon in the 1920s.


What are the two types of waves that display red shift?

The terms "redshift" and "blueshift" are used for electromagnetic waves. However, the underlying phenomenon - namely, the Doppler shift - applies to any type of wave.


What is used to know what way a star is going?

We can tell that our universe is expanding because stars and galaxies we observe have a definite red tint to them. This phenomenon known as "red shift" allowed us to have evidence that our galaxy was and has been expanding. In addition to relic radiation, this helps to prove the Big Bang theory.


What is the opposite of the red shift?

The opposite of the red shift is the purple shift.

What does it mean if a star is experiencing a red shift?

redshift is what happens when visible light gets longer in wavelength, thus shifting toward the red end of the spectrum of visible light. This is a phenomenon that occurs when the light source is moving away from the observer.


What are differences in colors of moving objects in space that are approaching and moving objects that are moving away?

Objects moving toward you will have a blue shift in their spectrum and objects moving away from you will have a red shift in their spectrum. This is known as a doppler shift.
