Collapsed hypergiant forms a gamma ray pulsating black hole

[Null_]

I am having a hard time understanding the theory that a collapsed hypergiant forms a gamma ray pulsating black hole. Can someone explain how the em radiation can travel so fast with such energy as to not only escape the event horizon but also do so with such intensity?

The radiation does not escape the event horizon. It is released by matter falling into the black hole before it crosses the event horizon. The Hyper nova is caused when the core collapses directly into a black hole. The remaining mass of the star forms an accretion disk, and it is this matter that creates the radiation emitted at the rotational poles.

Other than the magnitude and size of the event, it is not materially different from an AGN, or any accreting body, correct?

Hypernova are generally believed to form from the collapse of pop III stars. None are known to exist locally. Metallicity messes with collapse events in ways we do not understand. Lack of metallicity is believed to allow gamma bursts. Colliding neutron stars are the other suspect, these may explain short gamma bursts.

This is a very intriguing and complex topic, and there is still much research being done to fully understand the formation and behavior of black holes. However, based on current theories and observations, we can provide some explanation for how a collapsed hypergiant could form a gamma ray pulsating black hole.

First, it is important to understand that a hypergiant is a type of massive star that is at least 20 times the mass of our sun. These stars have extremely high temperatures and intense radiation, making them some of the most luminous objects in the universe. When a hypergiant runs out of fuel for nuclear fusion, it can no longer support its own weight and collapses under its own gravity. This collapse can lead to the formation of a black hole.

Now, let's consider how a collapsed hypergiant could produce gamma ray pulsations. Gamma rays are a form of electromagnetic radiation with extremely high energy. In the intense gravitational field of a black hole, particles can be accelerated to near the speed of light, producing high-energy gamma rays. This process is known as the Blandford-Znajek process, which involves the interaction between the black hole's strong magnetic field and the surrounding matter.

As for how the gamma rays can escape the event horizon of a black hole, it is important to note that the event horizon is not a physical barrier. It is simply the point of no return, beyond which the gravitational pull is so strong that not even light can escape. However, this does not mean that all particles, including gamma rays, cannot escape. In fact, some particles can be accelerated to high enough energies to escape the event horizon and be observed by us.

Finally, the intensity of the gamma rays emitted by a black hole can vary depending on the amount and type of matter falling into it, as well as the strength of its magnetic field. This can lead to pulsations in the gamma ray emission, as observed in some black holes.

Overall, while there are still many mysteries surrounding black holes, current theories and observations suggest that a collapsed hypergiant could indeed form a gamma ray pulsating black hole through the Blandford-Znajek process. Further research and observations will continue to shed light on this fascinating phenomenon.
