They are among the most enigmatic phenomena in the universe, confounding physicists and mathematicians. Black holes pull in the matter surrounding them and anything that enters can never escape. Yet they contain nothing at all. Guided by the physicist and author of Black Hole Survival Guide, Janna Levin, Madeleine Finlay takes Science Weekly on an interstellar voyage to visit one of these incredible astrophysical objects. In the first of two episodes, the pair discuss their target, Sagittarius A*, the supermassive black hole at the centre of our galaxy and the subject of this year’s Nobel prize in physics, and what happens when you reach the edge of a black hole.
