Accretion to Primordial Black Hole (PBH): Exploring Extreme Conditions

In summary, the conversation is about the process of accretion to primordial black holes, specifically when the black hole is captured by a compact object. The person is curious about what happens to the material or "blob" that falls into the black hole and how much it is squeezed. They are also looking for ideas or references on this topic.

Hello,
I would like to examine or learn something about accretion to Primordial Black Hole (PBH) captured by some compact object (sitting in the center). How is this happening? What is happening to material, "blob", which is falling to PBH? How much is squeezed?
Can you somebody let me know some ideas or references?

Thank you very much.

Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

Primordial black holes are somewhat speculative, but you're basically asking about what happens to matter that falls into any black hole. You may get more and better answers in the relativity forum.
 

1. What is a primordial black hole (PBH)?

A primordial black hole is a hypothetical type of black hole that is believed to have formed in the early universe, shortly after the Big Bang. They are thought to have formed from the gravitational collapse of regions of high density in the early universe, and are much smaller than the black holes that form from the collapse of massive stars.

2. How do PBHs differ from other types of black holes?

PBHs are unique in that they are thought to have formed in the early universe, while other types of black holes form from the collapse of massive stars. PBHs are also much smaller, with masses ranging from a few grams to a few hundred thousand times the mass of the sun.

3. What is accretion to a PBH?

Accretion is the process by which matter, such as gas or dust, is pulled into a black hole's event horizon and becomes part of the black hole. In the case of PBHs, this can happen when they pass through regions of high density in the universe, such as a cloud of gas or a galaxy.

4. How does exploring PBHs help us understand extreme conditions in the universe?

PBHs provide a unique opportunity to study extreme conditions that existed in the early universe. By studying the accretion process and the behavior of matter around PBHs, scientists can gain insights into the physical processes that govern the universe, such as the formation of galaxies and the evolution of the universe.

5. What are some potential applications of PBH research?

Studying PBHs and their accretion can have practical applications in areas such as cosmology, astrophysics, and particle physics. It can also help us understand the formation and evolution of structures in the universe, and could potentially lead to advancements in technologies such as space travel and energy production.
