Black Holes: Searching for the Unknown

For August 2023, The Sky at Night team investigate the science of black holes and discover the incredible techniques being used to uncover their secrets, and even help us answer bigger questions about our universe. Chris meets Dr Becky Smethurst at the University of Oxford to learn how a black hole forms from the death of a star. He also investigates whether black holes deserve their menacing portrayal in popular culture. He describes what would happen if we got too close to the event horizon and how black holes might actually play a role in lighting up the universe. Maggie explores how scientists are trying to understand more about black holes by meeting Dr Tessa Baker, who works on LIGO. The Laser Interferometer Gravitational-Wave Observatory is one of the world’s largest physics experiments and is not your usual type of observatory; instead of looking - it listens. The next observation run has just started, and Maggie learns what they are hoping to find.
