Does the center of a quasar experience time dilation?

In summary, the OP read that the centre of a quasar does not or almost doesn't experience time dilation, but did not provide a reference to back up their assertion.

I recently read that the center of a quasar does not or almost doesn't experience time dilation, can anybody help me understand this more? The text didn't help much.

Can you give a reference?

How could centre of a quasar doesn't suffer time dilation as the quasar is formed by a supermassive black hole at the centre which compresses the gases in accretion disk and in resultant these gases radiate.

Ref:
http://en.wikipedia.org/wiki/Quasar

Have a look at the first paragraph of the article

I don't see anything about time dilation in any of the first few paragraphs.

In first paragraph it is clearly written that a quasar is a resultant of a black hole and it is already been proven that the phenomena of time dilation is strange yet experimentally confirmed effect of relativity theory so if at the centre of the quasar there is a black hole than there is time dilation

Of course, but it doesn't say anywhere that time dilation does not occur, which was your assertion, or at least the OP's assertion (it is hard to figure out what you were trying to say).

that's what I am saying...

when there is a black hole at the centre there is a time dilation....so it is clearly written in that reference that there is a black hole at the centre of the quasar and it has already been proven in relativity that there is a time dilation in black hole so resultant is that there should be a time dilation in a quasar as well.

This is a) not High Energy and Nuclear Physics, and b) it has turned into "Guess what the OP meant". The OP seems uninterested in clarifying this, so I'm closing this thread.
 

Related to Does the center of a quasar experience time dilation?

1. How does time dilation occur in quasars?

Time dilation in quasars occurs due to the extreme gravitational pull of the massive black hole at the center of the quasar. This causes a distortion in the fabric of space-time, resulting in time passing at a different rate for an observer near the black hole compared to an observer far away.

2. How is time dilation in quasars measured?

Time dilation in quasars can be measured by observing the redshift of light emitted from the accretion disk around the black hole. As the light travels through the gravitational field, it is stretched, causing a longer wavelength and a redshift. This redshift can be compared to the expected wavelength, allowing for the calculation of the time dilation factor.

3. Can time dilation in quasars affect objects or organisms near them?

Yes, time dilation in quasars can affect objects or organisms near them. The closer an object is to the quasar's black hole, the stronger the gravitational pull and the greater the time dilation effect. This can have a significant impact on the aging process and the perception of time for these objects or organisms.

4. Is time dilation in quasars constant or does it vary?

Time dilation in quasars is not constant and can vary depending on the distance from the black hole and the speed of the observer. The closer an observer is to the black hole, the stronger the time dilation effect. However, as the observer moves further away, the time dilation effect decreases.

5. How does time dilation in quasars impact our understanding of the universe?

Time dilation in quasars is a key factor in understanding the behavior of gravity and the effects it has on the fabric of space-time. It also plays a crucial role in the study of the early universe and the formation of galaxies. By studying time dilation in quasars, scientists can gain a better understanding of the fundamental laws of the universe and how it has evolved over time.
