Can a black hole be stabilized through Hawking radiation and mass feeding?

AI Thread Summary
The discussion explores the theoretical stabilization of black holes through a balance of Hawking radiation and mass feeding. It suggests that if a black hole's radiation output could be countered by a consistent influx of mass, it might achieve a dynamic stability. The potential creation of mini black holes in particle colliders raises questions about practical applications. The conversation also highlights the need for a black hole to gain mass over time to maintain equilibrium with the cosmic microwave background (CMB). Overall, harnessing such a process would represent a significant scientific advancement.

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.

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.
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
