What is the minimum amount of matter that may form a black hole?
gpt
There is no real minimum of what *could* form a black hole if it is compressed into a small enough volume (except possibly below the Planck mass...not sure of this), however, the smallest amount that will *actually* form a black hole due to gravitational collapse is roughly twice the mass of the sun, although the exact value isn't known.
