Gravastar vs. Neutron Stars: A New Theory for Black Hole Formation?

In summary, the conversation discusses the possibility of gravity waves being the result of a type of supernova remains called a Grav-Star. There is skepticism about this theory and the need for scientific references to support it. The concept of a Grav-Star is compared to a neutron star, but more research is needed. The discussion is paused until more information can be gathered.

Has anyone else heard of that gravity waves may be the result of another type of supernova remains, called a Grav-Star? It seems almost to physically mimic a neuron star but stopped just shy of becoming a black hole, yet it still has enough of a gravity well to prevent light from escaping. Is that even possible? To have enough mass to have black body absorbtion properties but not enough to become a sinking (into space-time fabric) singularity. Sounds highly improbable. Thoughts?

never heard of it, nor has google

please supply GOOD scientific references to where you are reading this

My immediate thought was a neutron star which was dense enough to have a photon sphere, but not so dense as to form a black hole. But then I know nooothing, as Manuel so elegantly put it.

We really need to have some kind of decent reference. Threads like this one, without some kind of substantiation, achieve very little. I'll check back in a day and see where we are.

Okay -
Gravastar - alternative explanation for black holes
https://en.wikipedia.org/wiki/Gravastar

This kind of thing is on the edge of what PF discusses. I am locking the thread until a mentor who knows about this can figure out where we stand.
 

1. What is a grav-star?

A grav-star, also known as a black star, is a hypothetical type of celestial object that is predicted to exist as an alternative to a black hole. It is theorized that a grav-star would have a singularity at its center like a black hole, but the singularity would not be hidden behind an event horizon.

2. What is a neutron star?

A neutron star is a type of celestial object that forms when a massive star collapses in on itself during a supernova explosion. It is composed almost entirely of neutrons and is incredibly dense, with a mass greater than that of the sun packed into a sphere the size of a city.

3. How do grav-stars and neutron stars differ?

The main difference between grav-stars and neutron stars is the presence of an event horizon. Neutron stars have a visible surface and a boundary known as the neutron star crust, while grav-stars do not have a surface and are not bound by an event horizon. Additionally, neutron stars are made up of neutrons, while grav-stars are made up of exotic matter.

4. Can we observe grav-stars and neutron stars?

Neutron stars have been observed and studied by scientists through various methods, including radio and X-ray observations. However, grav-stars are still theoretical and have not been observed or confirmed to exist, so we cannot currently observe them.

5. Which is more dangerous, a grav-star or a neutron star?

Both grav-stars and neutron stars are incredibly powerful and dangerous objects in space. However, grav-stars are still hypothetical and their behavior and effects are not fully understood. Neutron stars, on the other hand, have been observed and are known to emit powerful bursts of radiation, making them potentially dangerous to objects nearby.
