String stars instead of black holes?

In summary, according to the content, a Kerr ring singularity may basically be a closed string, and general relativity has the mass compressing to a singularity, but quantum theory makes this highly unlikely. As far as the fuzzball hypothesis goes, it's almost exactly what was in the content, but broken.

Hey guys.
If the string theory is correct (and strings are fundamental and the last building block) I had a thought that if and when a star collapses (due to whatever reason) it can reach neutron star status. Add more mass and it can collapse to a quark star. Now say that we add more mass and it collapses even further - to a black hole. But if strings are there and are so rigid as they should be, maybe they can withhold this last collapse. The star shrinks by a huge factor (since strings are so small, even compared to quarks) but never reaches the black hole point-state. We would have a mind-numbingly small chunk of material all in all resembling a black hole, but but not infinitley small...

That would take away the infinites of black holes... small and dense? yes! infinite? no!


Thoughts?

Hello, I had the same idea several years ago that a Kerr ring singularity might basically be a closed string.
-I mean they both spin in one direction only and are incredibly flat and thin (one dimensional).
-Their size is on the order of Planck’s length.
-The singularity's spinning surface is wriggling quantum foam and a string’s surface vibrates.
-A closed string vibrates to represent nuclear particles and the higher the frequency the more mass the particle has. Since they are one dimensional, if a googol strings were crushed onto each other by gravity, then they would still look like one closed string (or ring singularity). However from harmonics, the frequency of the vibration would multiply and become infinitely high, thus representing a particle of incredible mass, like a singularity.
-As you mention, we already know that gravity can implode a star into neutrons (and perhaps quarks), so why not even smaller basic structures?
It just seems to me that string theorists might like to know that GR may actually predict string-like structures. Unfortunately, it is not possible to prove this.

Black holes are masses small enough so that the escape velocity is greater than the speed of light. What happens inside the hole is very much an open question. General Relativity has the mass compressing to a singularity. However quantum theory makes this highly unlikely. In any case attempts to reconcile them (GR and quantum) here lead to nonsense. Someday string theory may resolve this problem, but it remains open for now.

Thanks for the Fuzzball link. It was almost exactly as what I was thinking of. Reading about it now, I remember browsing the subject long ago.

Thanks again
 

1. What are string stars?

String stars are a theoretical concept proposed by physicists as an alternative to black holes. They are made up of one-dimensional strings of energy rather than the infinitely dense singularity found in black holes.

2. How are string stars formed?

String stars are formed through the collapse of massive stars, just like black holes. However, instead of collapsing into a singularity, the strings of energy become tightly wound and form a stable object with a finite size.

3. How do string stars differ from black holes?

String stars differ from black holes in several ways. They have a finite size and do not possess an event horizon, which is the point of no return for objects entering a black hole. Additionally, they do not have the same intense gravitational pull as black holes.

4. Can string stars be observed or detected?

Currently, there is no direct evidence for the existence of string stars, so they cannot be observed or detected. However, some physicists believe that they may leave behind a unique signature in gravitational wave signals, which could potentially be detected by advanced technology in the future.

5. How do string stars impact our understanding of the universe?

The concept of string stars challenges our current understanding of the universe and the laws of physics. If they do exist, they could provide new insights into the nature of gravity and the structure of spacetime. They also have the potential to help reconcile the theories of general relativity and quantum mechanics.
