Who's Afraid of a Big Black Hole?
Weighing in at up to four million times the mass of the Sun, the biggest super massive black holes have the power to rip planets apart and swallow entire stars. Their gravitational pull is so strong that nothing, not even light, can escape. And that's a problem for astronomers, because it means they're entirely invisible to any telescope. Despite these obvious obstacles, 'Who's Afraid Of A Big Black Hole' meets the astronomers attempting to image a black hole for the very first time and the theoretical physicists getting ever closer to unlocking their mysteries. It's a story that takes us into the heart of a black hole and to the very edge of what we think we know about the universe.
