They are among the most enigmatic phenomena in the universe, confounding physicists and mathematicians alike. Black holes pull in the matter around them and anything that enters can never escape. Yet they contain nothing at all. Guided by the physicist and author of the 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 second of two episodes, the pair discuss spaghettification, white holes, Hawking radiation and whether we actually live inside a hologram. Help support our independent journalism at
