Discussion Overview

The discussion revolves around the hypothetical requirements for creating an artificial black hole with a mass of 1000 kg. Participants explore the theoretical implications, methods of creation, and the physical principles involved, including concepts from general relativity and quantum gravity.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions how to define the experiment for creating a black hole and suggests looking into primordial black holes for clarification.
  • Another participant proposes that an implosion acting on a spherical mass might be involved in the creation process.
  • Concerns are raised about the feasibility of creating a black hole smaller than an atom and the implications of quantum gravity on the collapse process.
  • It is noted that a small black hole would evaporate very quickly, raising questions about its existence and stability.
  • Participants discuss the mass required for a black hole to persist when subjected to external forces, with one noting that classical general relativity does not impose a minimum mass limit.
  • One participant expresses that the original question is too vague and has not been adequately clarified.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the feasibility and theoretical underpinnings of creating an artificial black hole, with no consensus reached on the specifics of the process or the definitions involved.

Contextual Notes

The discussion highlights limitations in defining the experiment, assumptions about the nature of black holes, and the interplay between classical and quantum theories, which remain unresolved.

In a hypothetical deep space experiment in the distant future with appropriate safety precautions in place, how much force/power/energy would be required to create an artificial 1000kg black hole? I haven’t the faintest clue & this isn’t for homework. Where would I even begin looking for an answer?

Before doing that, you need to make the question well-defined. How is this proposed experiment going to create a black hole?

To help clarify your thinking, you might want to look up literature on primordial black holes.
 
I was assuming some type of implosion would be involved acting on a spherical mass.

How is the implosion created?

(In the case of primordial black holes, the implosion would be created by large enough density fluctuations in the early universe.)
 
What Peter is likely getting at is that the black hole is smaller than an atom. How do you use atoms to squeeze it if it's smaller than one?

Don't we also have the problem that for such a small black hole (##R_S\approx 10^{-24}\mathrm{m}##) you'd need quantum gravity to describe the collapse process, anyway? Or are we just assuming classical gravity is fine for the sake of argument?

There's lots of problems. Such a black hole will evaporate in 10^-18 seconds, so whether it "exists" or not is a subject for debate.

The question it reminds me of "Can God create a stone so heavy he can't lift it?"

How much mass does it need to have where if you throw a big enough cloud of particles at it, it persists?

I'm not sure what you mean by this, but if you mean, is there a minimum possible mass for a black hole, classical GR, which is the subject matter in this particular forum, does not have any such limit.

The OP question is too vague to be answered and has not been clarified. Thread closed.
