Shaw Laureate Public Lecture: The Active Social Lives of Black Holes
It is now clear that stars sometimes become black holes and that most normal galaxies have a massive black hole, in their nuclei. However, while pop-culture often depicts them as frightening cosmic monsters, black holes can interact - sometimes strongly, sometimes subtly - and often benevolently, with their environment. Massive black holes can attract gas and cause it to shine brighter than their galactic hosts. Black holes can use their rotation to create twin jets flowing outwards with speeds close to that of light. They can shatter stars which wander too close. They can also acquire black hole partners which become locked in an ecstatic dance before merging and creating a burst of gravitational waves – ripples in the fabric of space-time that travel at the speed of light. We have learned, are learning and should soon learn much more about each of these interactions, as the speaker shall try to illustrate.
