Black holes are arguably the most mysterious of all objects in the universe.
They cloak behind their horizons, as proven by Prof. Roger Penrose (2020, Physics Nobel), ``singularities” or places where space and time become infinitely curved and known physical laws break down. From the stuff of science fiction, black holes have today taken observational centrestage being regularly seen using gravity waves and other clever methods. The most remarkable and mysterious features of black holes are revealed when we include the effects of Quantum Mechanics as first done by Prof. Stephen Hawking. The puzzles emerging from these studies have turned black holes into key theoretical laboratories for understanding what happens when quantum mechanics and gravity come together. I will try to explain some of the most recent developments in this research that is reshaping our view of space and time !
