    Black hole Hole Stable
Click For Summary

Discussion Overview

The discussion revolves around the theoretical possibility of stabilizing a black hole through the balance of Hawking radiation and the mass that could be fed into it. Participants explore concepts related to black hole dynamics, the effects of cosmic background radiation, and the implications of creating mini black holes in experimental settings.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant suggests that if Hawking radiation exists, a black hole could theoretically be stabilized if its output is in equilibrium with the mass fed into it, potentially achievable with mini black holes created in particle colliders.
  • Another participant mentions an influx of blue-shifted light, cosmic microwave background (CMB), and dark matter into cosmic black holes, questioning how this might counteract Hawking radiation and suggesting that black holes could grow instead of evaporate.
  • A different viewpoint posits that a black hole can achieve dynamic stability if its temperature matches that of the CMB, implying a need for mass gain over time.
  • One participant calculates that a black hole with a mass of 228 metric tons would evaporate in one second due to Hawking radiation, indicating the necessity of continuously feeding mass to maintain its viability.

Areas of Agreement / Disagreement

Participants express various hypotheses regarding the stabilization of black holes, with no consensus reached on the mechanisms or feasibility of such stabilization. Multiple competing views remain regarding the interplay of Hawking radiation, mass feeding, and cosmic influences.

Contextual Notes

Participants acknowledge the need for specific conditions, such as the black hole's temperature and mass influx, but do not resolve the complexities involved in these interactions. The discussion also highlights the speculative nature of creating and maintaining mini black holes.

Who May Find This Useful

This discussion may be of interest to those exploring theoretical physics, black hole dynamics, and the implications of Hawking radiation in cosmology.

If a black hole really does have hawking radiation can in theory the black hole be stable. What I mean by this is that the hawking radiation output is in equilibrium with mass that we could feed a black hole. It seems to be self explanatory and if the large hadron collider could create a mini black hole could this soon be a possibility. This would be easier achieved if the black hole had a net charge and could be suspended in a chamber of some sort. I would imagine such a thing would be an amazing feat of science and manpower and would be a huge step for mankind.
 
Astronomy news on Phys.org
I can't find the source but I've seen text that states that there is an almost constant influx of highly blue-shifted light, CMB and dark matter falling into a cosmic black hole. To what degree this counter-acts the Hawking radiation I'm not sure but considering how long it takes for a black hole to evaporate through the Hawking process and the energy in radiation such as gamma and x-rays, if anything the black hole might grow.

A black hole can be dynamically stable if it's current temperature is the same as the CMB. This requires it to gain mass over time.
 
A 228 metric ton black hole would evaporate in 1 second from Hawking Radiation, so basically you would have to drop this much mass into to it every second to keep it viable, creating a continuous five million megaton blast.

Somehow harnassing this would indeed be an amazing feat.
