:How small can a singularity be? How small is the smallest mass? What is "one" quanta of mass? Damned if I know, but it can't be all that difficult to find out. Ask those blokes at the birthplace of the web. : :

: Well that is not the same thing, you need Enough mass to generate gravity strongenough to hold light to have an event horizon...

:No you don't. Mass has nothing to do with it. ANY mass that becomes a singularity has no dimension. Since it has mass but no dimension then it figures that its gravitational pull is at some point from the centre of the singularity strong enough to form a black hole. Albeit very very tiny indeed. The real question I suppose is how small a mass can a singularity be. Or to be precise, a fragment of a singularity, since a small one could not form all by itself. Either in the context of how small an object can form a singularity or how small can it be before the ordinary laws of physics of a larger body be compromised.Is it possible to have a really really small singularity. Particle sized fragments? If it is possible, then it goes without saying that that singularity will have a really really small event horizon - but it will have one.
