Observe Hawking Rad. in Black Hole?

In summary, the phrase "a black hole within the black hole" does not make any sense, as there is no such thing nor can there be. It is possible for an observer inside the hole to detect radiation being emitted from the black hole, but this is speculation and cannot be proven.

TL;DR Summary
Theoretically could an observer in a black hole perceive hawking radiation escaping the black hole they were in as a black hole within the black hole.
Theoretically could an observer in a black hole perceive hawking radiation escaping the black hole as a black hole within the black hole? Also if so maybe that black hole could produce a radiation similar to or related to hawking radiation (Making a strange entangled system for conservation of information.) I do realize this is a bit off the wall.

(1) The phrase "a black hole within the black hole" does not even make any sense, as there is no such thing nor can there be.

(2) Since Hawking Radiation moves AWAY from the BH, it would not be visible from inside the event horizon

There is no such thing as "a black hole within a black hole".

I believe that a black hole that is emitting Hawking radiation outward will also be sending some form of radiation inward, so it might be possible for an observer inside the hole to detect that ingoing radiation. But I have not seen any detailed analysis of this in what I have read on Hawking radiation.

Several speculative posts based on misunderstandings of Hawking radiation and meaning of the phrase “thought experiment” have been removed from this thread.

All posters are asked to limit the discussion to the question in the thread title.

I realize the limitations of what we can observe so this situation I am proposing is more of a base for speculation.
And speculation can be fun but it is specifically forbidden on this forum. Please read the rules you agreed to when you signed up.

Note that Peter corrected me and pointed out that part of Hawking Radiation DOES fall back into the hole. I knew that but forgot.

I will do that sorry i just want to get a better understanding of the elements at work in the system so i have edited my post to remove the word speculation. i sincerely want to engage in this topic respectfully and want would like others input in helping me better understand what is possible and what is not in the context of how best I can understand things that relate to how i think.
To be honest, what you're writing is not physics - it's just playing with words. For example:

Logically or mathematically I cannot come up with a way of defining an internal barrier from within the Event horizon.

Has no well-defined meaning. There's no physics there to discuss.

I understand you point. obviously there a language barrier for me that i cannot cross

I see your point. yes i agree. obviously there is a language barrier I am not able to cross. if you are willing to listen bare with me and i will post the physics that lead me to this assertion. unfortunately for us both my ability to correctly implement and understand maths is pretty bad due to the education i received and i prefer logic. If you don't think this is a good use of your or the forums time i fully understand and appreciate that.

As has already been noted, personal speculation is off limits here. The fact that you think your speculations are "physics" does not change that.

"Logic" without math, at least as far as physics is concerned, is not useful; physics is expressed in math, so if you want to usefully discuss physics, you need to learn the math. Even if the education you received up to now did not give you a good grasp of math, you can still fix that; education is not a process that stops once you leave school, you can always educate yourself further.

The title question of the thread has been answered. Thread closed.
 

1. What is Hawking Radiation?

Hawking Radiation is a theoretical phenomenon proposed by physicist Stephen Hawking in the 1970s. It is a type of radiation that is emitted by black holes due to quantum mechanical effects near the event horizon.

2. How is Hawking Radiation observed in black holes?

Hawking Radiation cannot be directly observed because it is very faint and difficult to detect. However, scientists can observe its effects on the surrounding matter and energy, such as changes in the mass and spin of the black hole.

3. What is the significance of observing Hawking Radiation in black holes?

Observing Hawking Radiation in black holes would provide evidence for the existence of this phenomenon and further support Hawking's theories on the nature of black holes. It could also help scientists better understand the behavior of black holes and their role in the universe.

4. How do scientists study Hawking Radiation in black holes?

Scientists use a variety of methods to study Hawking Radiation, including mathematical models, computer simulations, and observations of black holes and their surroundings using telescopes and other instruments.

5. Is it possible to harness Hawking Radiation for energy?

While Hawking Radiation is a form of energy, it is extremely weak and difficult to capture. Additionally, the amount of energy emitted by Hawking Radiation is minuscule compared to the massive energy output of black holes. Therefore, it is currently not feasible to harness Hawking Radiation for energy purposes.
