"Black holes: observation, theory and geometry" by Dr Oisin MacConamhna.
He will discuss the astrophysical evidence for massive, compact black
objects in our universe, and the processes by which they can be
formed. General relativity interprets these objects as black holes -
regions of spacetime in which gravity becomes so strong that nothing
can escape. He will explain the main features of their physics, as
predicted by relativity and quantum theory, in non-technical language.
Finally he will discuss, again in a non-technical way, some of the
extraordinary properties of so-called supersymmetric black holes,
which place them at the centre of current research in string theory
and pure mathematics.
