Do black holes actually have dimension (I mean size)?
Thanks. :yuck:

a schwarzschild BH is Zero-dimensional, a point. A Kerr BH one-dimensional, a circle.
there's a solution of Einstein Equations called Myers-Perry metric that describes 5-dimensional Black Hole spacetimes. In this case I'm not sure of the dimensionality of the BH (somebody can explain?)
