What is Redshift?
A redshift can occur when electromagnetic radiation is reflected or emitted by an object that is pointed toward the "red" end of the electromagnetic spectrum. This effect causes an increase in the wavelength of the electromagnetic radiation... Read More »

What is redshifting?
Hubble said "redshifting" "is a hitherto unknown principle of nature." Unfortunately, not too many physicists listen to Hubble. Red shifting is a measure of direction not motion. Redshifting indicates direction away from the center. If the ... Read More »

How to Calculate Redshift
Redshift is a term used in astronomy to describe the displacement of light waves toward the red end of the spectrum. Waves that shift in this manner are considered to be lengthening, which is one of the evidences used to judge that the dist... Read More »

The redshift was not "invented" by anyone. It is a natural phenomenon that has always been with us. It was the Austrian mathematician and physicist Christian Doppler who first described the effect in the year 1842. The idea was latched onto...

Due to the Doppler effect, the faster a body moves away from you the larger its wavelength - meaning it tends to get more red. It was discovered that the further away a galaxy is from us, it is moving faster. So large redshift means a galax...

Red shift is caused by object in space moving away from us. As space expands it appears that stars are moving away from us and are redshifted. From the red shift it is possible to estimate how far away the star is because stars further away...

A redshift can be created by several mechanisms; one that is of great interest to astronomers is the Doppler effect: if an object comes towards us, or goes away from us, the frequence of the light we receive from that object, changes.
