Gravastar One Star Proposal



Souce


This news came out recently, on June 11, it is not that they have discovered a Granastar or a gravitational condensed star, that would be the definition, it is not that they have discovered it, but that they have done a new theoretical research on how a Gravastar can work and how a Gravastar can exist, which is a very rare object in the universe, it would be like finding a four-leaf clover that will also not last long because it is not a state that lasts long, it is a very rare state of equilibrium.


On June 11, physicists from Goethe University Frankfurt in Frankfurt, Germany, physicists Japolski and Rezoya, proposed an alternative for creating this type of objects, that is, a mechanism by which Gavastares can be created. It is not a black hole, it is almost a black hole, it is almost as dense as a black hole, but it does not have singularity, which is that point where the laws of physics are broken and we do not know what is happening or what is beyond, it would not have either. event horizon, which is the point of no return.


In its place it would have a kind of layer of normal matter, which is already beginning to be rare on the outside, and also dark energy on the inside that exerts depression outwards, that is, it would be a massive, normal star, it would condense as happens with a black hole, what happens is that it would not have enough mass to transform into a black hole and inside it would have dark energy.

So, this massive star would condense, concentrate, basically collapse, but inside it would have dark energy, so it would never completely collapse, it would remain in a balance between the gravity that is pushing towards the center to create the black hole and the dark energy that you would be pushing outwards.


This type of star or whatever, because in reality they would not emit light, on the outside it would be like a black hole, it can be differentiated by gravitational waves and some nuances, but on the outside it would be the same as a black hole, but on the inside no, it would have neither singularity nor event horizon and it would have that strange balance between the gravity that is pressing towards the center and the dark energy that would be shining outwards. That's why they say it's like it has a universe inside expanding due to dark energy.


It would not be a universe as we understand it, because even so inside there would be a brutal density of matter and energy, so it would not be a typical universe with stars, planets, etc. Problems with this type of objects. First, the researchers do not explain where the dark energy comes from, it is assumed that the dark energy was all generated during the Big Bang and since then it has been pulling the cosmos on a cosmic scale, it is not concentrated in a specific point, it would be a little strange if it were concentrated inside a star that has collapsed.


Second point of conflict is that a very precise balance is needed between the gravity that pushes towards the center and the dark energy that pushes outwards, so if that object ends up absorbing, for example, another star or a planet, because externally it would look like a black hole and logically it would continue to have gravity and would continue attracting objects towards it, if it ate something, then that extra mass could unbalance by being taxed and in the end end up gaining gravity, which would end up collapsing into a hole.
