Discussion Overview

The discussion revolves around the formation and existence of a supermassive black hole detected in the early universe, specifically its implications for the age of the universe and the nature of redshift measurements. The scope includes theoretical considerations, observational astronomy, and potential implications for cosmology.

Discussion Character

  • Exploratory, Debate/contested, Technical explanation

Main Points Raised

  • Some participants highlight the detection of a supermassive black hole in a quasar that emitted light just 690 million years after the Big Bang, suggesting the universe may be older than previously thought.
  • One participant questions whether the observed redshift might be influenced by photons emitted near the event horizon of the black hole, proposing that it may not be entirely due to cosmological factors.
  • Another participant expresses uncertainty about the implications of the black hole's formation during the reionization epoch, suggesting potential errors in observations or in the estimated age of the universe.
  • A participant seeks clarification on how the existence of this black hole contradicts the established age of the universe.
  • Some participants suggest that this thread may be related to another discussion about the timing of black hole formation, proposing a merge of the threads.

Areas of Agreement / Disagreement

Participants express differing views on the implications of the black hole's existence for the age of the universe and the nature of redshift. There is no consensus on whether the observations are accurate or if they challenge existing cosmological models.

Contextual Notes

The discussion includes uncertainties regarding the interpretation of redshift data and the conditions under which the black hole formed, with no resolution on these points.

A team of astronomers, including two from MIT, has detected the most distant supermassive black hole ever observed. The black hole sits in the center of an ultrabright quasar, the light of which was emitted just 690 million years after the Big Bang. That light has taken about 13 billion years to reach us -- a span of time that is nearly equal to the age of the universe.

May be the universe is older than we think?

I wonder whether the red shift observed and used to calculate distance might be in part due to the emitted photons coming from close to the event horizon, and it is not entirely a cosmological red shift.

I'm not sure but if this Black Hole formed during re ionisation some thing must be wrong, either the observation has errors or the age of the universe must be wrong.

How so? How does this contradict the age of the universe?
