There are few things seemingly so simple but potentially so complex as a ball of light. The phrase itself is ambiguous: does ball mean sphere or spheroid or spherical, does light mean light source or luminosity, and so on. Here are some of the things BOL may be - a physical object in its own right, as for instance ball lightning, earthquake lights, Saint Elmo’s fire, feux follets, etc., or plasma phenomena generated by electrical conditions not yet understood.
