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

In summary, the conversation touches on the topics of black hole singularity, quark stars, and quantum gravity theories. It is mentioned that a quark star is not the same as a black hole, and the only solution to the gravity interaction on small scales is one that is able to explain it. The conversation also briefly discusses the possibility of asymptotically safe or free gravity on small scales and mentions a talk on dark matter by Dan Hooper. The relevance of this talk to the original topic is questioned, and a revised version of the question is proposed. Finally, it is asked if a quark star is dense enough to have an event horizon visible to an external observer.

Is this a realistic solution to the black hole singularity problem,
Going beyond that, neutrino stars?

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?

1. What are quark stars?

Quark stars are hypothetical celestial bodies that are composed entirely of quarks, which are subatomic particles that make up protons and neutrons. They are believed to form when a massive star collapses and the pressure becomes so intense that the protons and neutrons are crushed together, forming a state of matter known as a quark-gluon plasma.

2. How are quark stars related to black holes?

Quark stars are proposed as a potential solution to the black hole singularity problem, which is the theoretical point of infinite density and zero volume at the center of a black hole. It is believed that quark stars could form instead of a singularity, as they would still have a high density but not be infinitely dense.

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

The idea of quark stars as a solution to the black hole singularity problem is still a topic of debate and further research is needed. Some scientists argue that quark stars may not be stable enough to form and survive, while others believe they could exist in the universe. Therefore, it is not yet clear if they are a realistic solution.

4. How can we detect or observe quark stars?

Quark stars are difficult to detect or observe because they are small and emit very little radiation. However, scientists have proposed several methods such as detecting gravitational waves, observing their effect on nearby stars and matter, or detecting high-energy particles emitted from their surface.

5. What implications would the existence of quark stars have on our understanding of the universe?

If quark stars are proven to exist, it would have significant implications on our understanding of the universe and the laws of physics. It could provide insights into the nature of matter and the extreme conditions that exist in the universe. It could also challenge our current understanding of black holes and the fate of massive stars.
