I wonder if black holes have a surface?
A black hole has zero dimensions and therefore no surface.
However, the 'event horizon' -- the point beyond which anything approaching the hole must fall into it -- is normally regarded as its 'surface'. The
size of the sphere formed by the event horizon varies with the mass of the black hole. Some black holes have event horizons wider than our Solar
It doesn't have the properties of a physical surface, though. It's just an imaginary sphere drawn in space.
