    Planck Star
In summary: The idea is that when matter collapses under its own gravity, it reaches a point where quantum effects become significant and cause a repulsive force that results in a bounce, similar to the quantum pressure that prevents electrons from falling into an atomic nucleus. This concept, known as the "bounce scenario," suggests that black holes may not be the end state of gravitationally collapsing matter and could potentially solve some long-standing problems in physics, such as the origin of powerful bursts of radiation from black holes and the paradox of information loss in black holes. It is also a possible explanation for the existence of dark matter. This idea is consistent with the theories of general relativity and quantum mechanics, making it a promising avenue for further exploration.

https://arxiv.org/pdf/1708.01789.pdf In line whit LQG which renders time(Tomita time) to evaluated differently.

Would it be possible for a bounce scenario in Blackhole. This is the update from the old paper of Planck Star http://arxiv.org/abs/1401.6562 . -- It is something to with how time dilation of extremes effects on observational aspect of BH.. Or bounce in a very slow motion in a extreme gravitational time-dilation.

"The gravitationally collapsing matter falls inside its horizon until its density reaches the Planck density, namely the quantity with the dimension of a density determined by the Planck constant ~, the Newton constant G and the speed of light c—these are the quantities that set the scale of quantum-gravitational phenomena.

At this stage, called “Planck star” [8], the star can still be much larger than the Planck length, but quantum effects are expected to make gravity strongly repulsive [9], triggering a bounce. The phenomenon is similar to the “quantum pressure” that prevents electrons from falling into an atomic nucleus." In line with question on Time. https://www.physicsforums.com/threads/about-time-to-think-about-time.936753/#post-5920350

For my question. 1) Can this explain why VSGRB in BH are so powerful? 2) Can we elimante the BH information paradox? 3) Some solution to problems on what makes dark matter? 3) It is a good a way to think that BH is some sort of bounce happened with enormous slowness seen by observers?

.. Of all the literature's and interpretations I've read. It is the closest to the natural(arbitrary) state physics(GR) that we know of.

A Planck star is a hypothetical star with a mass equal to the Planck mass, which is the smallest possible mass that a black hole can have. The Planck mass is the unit of mass in the system of natural units known as Planck units. The Planck mass is extremely large when expressed in everyday units. One Planck mass is equivalent to about 10 kilograms, which is about the weight of a grain of sand. A Planck star would have a radius of about 10 meters, which is about the size of a large picnic cooler.
 

1. What is a Planck Star?

A Planck Star is a theoretical object that is proposed to exist at the end of a black hole's evaporation. It is believed to be a remnant of a black hole that has completely evaporated and is characterized by a high energy density and a radius of around 10^-35 meters.

2. What is the possibility of a Planck Star actually existing?

Currently, the possibility of a Planck Star existing is purely theoretical and has not been confirmed through observational evidence. However, there are ongoing studies and research being conducted to explore the feasibility of its existence.

3. How does a Planck Star differ from a black hole?

A Planck Star is thought to be a remnant of a black hole, but it differs in several ways. Firstly, it has a much smaller radius, as mentioned before, and it also has a much higher energy density. Additionally, a Planck Star does not have an event horizon like a black hole does.

4. What implications would the existence of a Planck Star have on our understanding of black holes?

If a Planck Star is confirmed to exist, it would challenge our current understanding of black holes and their ultimate fate. It would also provide insights into the nature of gravity and the behavior of matter at extremely high densities.

5. What are the potential applications of studying Planck Stars?

Studying Planck Stars could lead to a better understanding of the fundamental laws of physics and could potentially provide insights into the behavior of matter in extreme conditions. It could also have implications for the development of new technologies, such as advanced propulsion systems, based on our improved understanding of gravity and matter.
