Synopsis

Modern astrophysics uses state-of-the-art technology to unravel the unknown on a cosmic scale. Among the many discoveries  are the heftiest things we know, namely giant black holes that inhabit the centres of galaxies. The early evidence for giant black holes that emerged  in the middle of the last century, effectively rested on the Sherlock-Holmes argument.  Today, however  we have the most direct evidence possible through the sharpest eyes that technology can make. The talk will cover some of the threads in this fascinating story.
