"In an early speculation, Stephen Hawking conjectured that a black hole would not form with a mass below about 10 kg (roughly the Planck mass). To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light. Some extensions of present physics posit the existence of extra dimensions of space. In higher … " - Minimum mass of black hole
