SUMMARY

The discussion centers on the concept of Planck stars as a potential explanation for black hole bounce scenarios and their implications for resolving physics paradoxes, particularly the black hole information paradox. It references the paper "Planck Stars" (arXiv:1401.6562) and introduces the idea that gravitational time dilation affects the observational aspects of black holes. The Planck star, characterized by its mass at the Planck scale, may trigger a bounce due to strong quantum gravitational effects, offering insights into phenomena such as very short gamma-ray bursts (VSGRB) and the nature of dark matter.

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.
