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

AI Thread Summary
Quark stars are proposed as a state of matter denser than neutron stars but distinct from black holes, not providing a solution to the black hole singularity problem. Current theories suggest that a true resolution would involve understanding gravity at very small scales. Some quantum gravity theories indicate that gravity may behave differently at these scales, potentially being asymptotically safe or free. The relevance of dark matter discussions to quark stars remains unclear, with some participants expressing reluctance to engage with lengthy talks. Ultimately, quark stars do not possess an event horizon visible to external observers.

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?
