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

Click For Summary

Discussion Overview

The discussion revolves around the concept of Gravastars as a potential alternative to neutron stars and black holes, particularly in the context of gravity waves and supernova remnants. Participants explore the theoretical implications and feasibility of Gravastars, questioning their properties and existence.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose that Gravastars could be remnants of supernovae that are similar to neutron stars but do not reach the density required to form black holes, raising questions about their gravitational properties.
  • One participant expresses skepticism about the possibility of a Gravastar having sufficient mass to exhibit black body absorption properties without collapsing into a singularity.
  • Another participant suggests that a neutron star could theoretically possess a photon sphere without being dense enough to become a black hole, although they acknowledge their limited knowledge on the topic.
  • Several participants emphasize the need for credible scientific references to substantiate claims about Gravastars, indicating a desire for a more informed discussion.

Areas of Agreement / Disagreement

Participants generally do not agree on the validity or existence of Gravastars, with some expressing skepticism and others exploring the concept. The discussion remains unresolved, with competing views on the topic.

Contextual Notes

There are limitations regarding the lack of scientific references provided, which affects the depth of the discussion. Participants also express uncertainty about the definitions and properties of Gravastars compared to neutron stars and black holes.

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 absorption 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.
