Exploring the Mysterious Particle-Antiparticle Radiation from a Black Hole

In summary, the process of particle-antiparticle radiation near a black hole involves one particle falling into the black hole and the other escaping, creating the appearance of negative and positive energy particles. Some theories suggest that the trapped particle could be the same as the escaping particle in a different direction on its "wordline," but this has not been proven and does not involve three particles.

Hi, my name is Mart Vabar.

Wikipedia has this somewhat heavy construction:

Physical insight on the process may be gained by imagining that particle-antiparticle radiation is emitted from just beyond the event horizon. This radiation does not come directly from the black hole itself, but rather is a result of virtual particles being "boosted" by the black hole's gravitation into becoming real particles.
A slightly more precise, but still much simplified, view of the process is that vacuum fluctuations cause a particle-antiparticle pair to appear close to the event horizon of a black hole. One of the pair falls into the black hole whilst the other escapes. In order to preserve total energy, the particle that fell into the black hole must have had a negative energy (with respect to an observer far away from the black hole).


Here we have 3 different particles: 2 of these appear near the event horizon; the 3rd one is a part of the black hole and it disappears, when it meets the particle with negative energy.

Could it make sense to simplify it and to see all these 3 as one single paricle:

1)

once upon a time it fell into the black hole,

2)

but for some good reason it cannot fit a "possible place" there anymore.

3)

So, from a viewpoint of an outsider, it seemingly moves "back" in time and when doing so, it looks like an anti-particle (to have some fun with it: like outer planets sometimes move "back")...

4)

... and when seemingly "going back" in time, the particle moves also out of the black hole,

5)

where it looks like a normal radiation with positive energy.


Comments anybody?

Are you asking a question or presenting a theory? The concept that the particle that escapes is the same as the particle trapped, but in a different "direction" in its wordline has been put forward, but nothing with 3 particles.
 

1. What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. It is formed when a massive star dies and its core collapses under its own gravity.

2. What is a particle-antiparticle pair?

A particle-antiparticle pair is a pair of subatomic particles, such as an electron and a positron, that have opposite charges and are created simultaneously from energy. When a particle and its antiparticle collide, they annihilate each other and release energy.

3. How does radiation from a black hole occur?

When a particle-antiparticle pair is created near the event horizon of a black hole, one particle may be pulled into the black hole while the other escapes. The escaping particle is then seen as radiation by an outside observer.

4. What is the significance of studying this radiation?

The study of this radiation can provide insight into the properties of black holes and the behavior of particles in extreme gravitational fields. It can also help us understand the origins and evolution of the universe.

5. How is this radiation detected?

This radiation can be detected through various methods, such as measuring the X-rays emitted from the accretion disk around a black hole or using telescopes to observe the effects of the radiation on nearby matter. Scientists also use mathematical models and simulations to study and understand the behavior of this radiation.
