Could a mass that is less than the critical mass required to produce a black hole be made into one through some collision or explosive force?

I think those black holes are called micro black holes (where they ever observed?). The smallest mass needed would probably be Planck mass.

The critical mass is actually defined by the volume into which you enclose it. Therefore, for a given mass you can find a volume for which a black hole will form. That is the idea behind those collision.Could a mass that is less than the critical mass required to produce a black hole be made into one through some collision or explosive force?

This is speculative, it has not actually been observed.

So that is not going to happen in an accelerator :surprisedI was thinking more along the line of a solar mass of about 13.5 times our sun.

Technically, no black hole is stable. They evaporate (and we are fairly conviced that this is correct, independently of models, I mean it does not rely on string "theory" or LQG or whatever... the calculations of Hawking are semi-classical QFT in curved space-time).If we assume that a mass of 14 times our sun is required for gravity alone to produce a black hole, could an implosive force (shock) compress the sub-black hole mass into a black hole and if so, would the resulting black hole be stable?

I must admit that I do not fully understand you concerns :uhh:
