SUMMARY

This discussion centers on the implications of Primordial Black Holes (PBHs) ranging from 1015 to 1024 grams interacting with celestial bodies such as the Sun or planets. The computed radius of these PBHs falls between 10-8 cm and 1 cm, comparable to atomic scales. The participant references key texts, including "Gravitation" by Misner, Thorne, and Wheeler and "Hydrodynamic Spherical Accretion" by Shapiro and Teukolsky, indicating a lack of comprehensive resources on the hydrodynamic implications of PBHs within other masses. The Wikipedia page on micro black holes is noted as a useful summary of current knowledge.

PREREQUISITES
  • Understanding of Primordial Black Holes (PBHs)
  • Familiarity with hydrodynamic principles in astrophysics
  • Knowledge of gravitational theories as outlined in "Gravitation" by Misner, Thorne, and Wheeler
  • Basic concepts of black hole physics and accretion processes
NEXT STEPS
  • Research advanced topics in black hole accretion dynamics
  • Study the implications of PBHs on stellar evolution and dynamics
  • Explore the latest findings in micro black hole physics
  • Investigate numerical simulations of hydrodynamic interactions involving PBHs
USEFUL FOR

Astronomers, astrophysicists, and researchers interested in black hole physics, particularly those focusing on the effects of Primordial Black Holes in extreme astrophysical environments.

Hello,
I have an extreme question :) Let's assume that here are Primordial Black Holes (PBH) in range 10^15 - 10^24 g for example. What would happen if some of them get into the some other object(Sun, Planet or compact object) and settle in the center (ideal case). I have computed radius of this PBHs, it is in range 10^(-8) - 1 cm (scale of atom 10^(-8)cm ). I have read Gravitation (MTW) paragraph "The fate of man who falls into the singularity" (p.680) and Black holes, white dwarfs and neutron star Shapiro, Teukolsky "Hydrodynamic spherical accretion" (p.412). But I mean if such PHB is within some mass, I can't interpolate this problem by hydrodynamical assumption etc. Do you know how describe this problem, something about that or if exists some text about this?
 
Physics news on Phys.org
The Wikipedia page on micro black holes gives a decent summary of the current state of knowledge:

https://en.wikipedia.org/wiki/Micro_black_hole

I don't know of any detailed treatments other than the Shapiro & Teukolsky one. Perhaps some of the other experts on PF do.
