Singularity. In the show this time, Dr Silke Britzen [03:38 - 09:40] tells us about a recent black hole meeting in Manchester and we find out about supermassive black hole formation from Prof Lucio Mayer [09:52 - 21:08] and ultra-luminous x-ray sources from Dr Philipp Podsiadlowski [21:19 - 32:02]. As always, Dr Tim O'Brien answers your questions [43:50 - 59:09] and we round up some odds and ends from the world of astronomy.
