Are quark stars a realistic solution to the black hole singularity problem?

Click For Summary
SUMMARY

Quark stars are proposed as a hypothetical state of matter that is denser than neutron stars but distinct from black holes. They do not possess an event horizon, making them observable to external observers. Current discussions highlight the need for a comprehensive theory of quantum gravity to address the singularity problem associated with black holes. The relevance of dark matter theories, such as those presented by Dan Hooper, is questioned in relation to the topic of quark stars.

PREREQUISITES
  • Understanding of quark stars and their properties
  • Familiarity with neutron stars and black holes
  • Basic knowledge of quantum gravity theories
  • Awareness of astrophysical concepts like event horizons
NEXT STEPS
  • Research quantum gravity theories, focusing on asymptotic safety and asymptotic freedom
  • Explore the characteristics and formation of quark stars
  • Investigate the implications of dark matter theories on stellar evolution
  • Study the differences between neutron stars, quark stars, and black holes
USEFUL FOR

Astronomers, physicists, and students interested in theoretical astrophysics and the nature of extreme states of matter.

Is this a realistic solution to the black hole singularity problem,
Going beyond that, neutrino stars?
 
Astronomy news on Phys.org
No. A quark star is not a black hole or vice versa.
 
The only solution would be the one which explains gravity interactions on very small scales.
Some tentative quantum gravity theories predict that gravity on very small scales is asymptotically safe or even asymptotically free.
 
Thanks.
I thought this interesting, but it doesn't get going until about 20m in.
 
How is a talk by Dan Hooper on dark matter relevant for the topic of the OP? I am not going to watch an hour of a popular talk just to figure this out.
 
OK thanks.
An improved version of my question is this?
Quark star is a hypothetical state state of matter which is more dense then a neutron star, but not a black hole.
Is it so dense that it would have an event horizon as far as an external observer can see?
