Does the center of a quasar experience time dilation?

Click For Summary

Discussion Overview

The discussion centers around the concept of time dilation in relation to the center of a quasar, particularly in the context of the supermassive black hole that is believed to reside there. Participants explore the implications of relativity theory and the behavior of time near black holes, with references to existing literature.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions the assertion that the center of a quasar does not experience time dilation and seeks clarification on the topic.
  • Another participant requests a reference to support the claim regarding time dilation at the center of a quasar.
  • A participant argues that since quasars are formed by supermassive black holes, the gases in the accretion disk would radiate due to the effects of the black hole, implying time dilation should occur.
  • There is a disagreement regarding the interpretation of a referenced article, with one participant stating it does not mention time dilation, while another insists that the presence of a black hole inherently involves time dilation.
  • One participant emphasizes that the existence of a black hole at the center of a quasar should lead to time dilation, based on established principles of relativity.
  • A later reply expresses frustration over the lack of clarity and suggests that the discussion has devolved into speculation about the original poster's intent.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether the center of a quasar experiences time dilation. There are competing views regarding the interpretation of existing literature and the implications of black hole physics.

Contextual Notes

The discussion highlights uncertainties regarding the interpretation of time dilation in the context of quasars and black holes, as well as the need for clearer references and definitions. Some assumptions about the nature of time dilation near black holes remain unaddressed.

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.
 
Physics news on Phys.org
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.
