Into the heart of darkness: supermassive black holes at the centers of galaxies

Black holes are among the most bizarre objects predicted by Einstein's theory of General Relativity. Many people may not realise that our own galaxy hosts a supermassive black hole at its centre that is three million times more massive than our own Sun! In this talk Professor Darren Croton from the Centre for Astrophysics and Supercomputing will discuss the physics of black holes and their formation, how they can grow to become so massive, active black hole "quasars" in the distant universe, and the unexpected impact that a supermassive black hole can have on the evolution of an entire galaxy. Professor Croton will finish by side stepping into the exotic world of wormholes, the black hole's tormented cousin. Presented on 21 October 2016.
