What does it mean that quasars are most common at a redshift of about 2?
Quasars being most common at a redshift of around 2 means that they were more prevalent in the universe's past. The redshift indicates their distance and age, suggesting that quasars were more abundant when the universe was younger. This redshift value corresponds to a time when many galaxies were undergoing intense star formation and black hole activity, leading to more quasars.
Do quasars have large or small redshifts?
Quasars typically have large redshifts, which indicate that they are moving away from us at high speeds. This redshift is due to the expansion of the universe and can help astronomers determine the distance and age of quasars.
What has the author David Tytler written?
David Tytler has written: 'Strong associated C IV absorption in low redshift quasars' -- subject(s): Absorption spectra, Interstellar gas, Quasars, Stellar spectra
What does the enormous redshift of quasars tell us about their velocity?
That they are receding at more than 90% the speed of light, and that they are not stars in our galaxy because we can't see change.
How do the properties of quasars suggest that the steady-state model of the universe is not accurate?
The high luminosity and redshift of quasars suggest they are located at vast distances from us and moving away at high speeds, which is inconsistent with a steady-state model requiring a static and unchanging universe. Additionally, the lack of young quasars in closer proximity to us contradicts the continuous creation of matter needed in a steady-state model.
What are the strengths and weaknesses of the redshift theory?
cons quasars have have large red shift that suggest they are far away as distant galexies some quazars with very high redshifts appear to be interacting with other galexies that have lesser redshift which would suggest that quazars have ann in trensic redshift pros its perfect evidence to show that the universe is expanding
Why are quasars only found in very distant parts of the universe?
The evidence for the extreme distance is the extreme redshift. Also, in many cases, a coincidence has been found between a quasar and a galaxy.The evidence for the extreme distance is the extreme redshift.

What is the quasar method?
The quasar method is a technique used in astrophysics to estimate the distances to distant celestial objects. It involves observing the spectra of quasars, which are extremely bright and distant objects, to determine the redshift caused by the expansion of the universe. By comparing the redshift of a quasar with known properties to that of a target object, astronomers can infer the distance to the target object.
Are distant objects in space called quarks or quasars?
quasars
When was The Redshift created?

When did Quantum Redshift happen?
Quantum Redshift happened in 2002.
How a quasars are formed?
Quasars are thought to be distant super-massive black holes.
