How hard does a boxer punch?

What is a good black hole candidate?
A good black hole candidate is typically a region in space where high-energy astrophysical phenomena are observed, such as X-ray emissions or gravitational lensing effects, without a visible source of light. This can indicate the presence of a compact and extremely massive object that is likely a black hole.
How big is the largest black hole known?
The most relevant quantity is the black hole's mass. Note that the black hole's diameter (the diameter of the event horizon, really) is directly proportional to its mass. The largest galactic black holes known seem to be around 20 billion solar masses. Check the Wikipedia "List of most massive black holes" for more details. Note that the mass of some of these black holes is not very well-known.
What is a non-example of black hole?
Examples of things which are not black holes would make a large list indeed.. but would include Abe Vigoda's spleen, the Symphony #3 in C Opus 78 by Camille Saint-Saens; and a box of dead marmots.
Where is Black Mountain located?

For example, there is one in Canberra, Australia, which gives its name to a national park; and another just outside the city of Belfast, Northern Ireland.
