Black holes, predicted by Albert Einstein’s general theory of relativity more than a century ago, have long intrigued scientists and the public with their bizarre and fantastical properties. Join us for a presentation of rare clarity of insight into the physics that makes black holes simple yet destructive manifestations of geometric destiny.
Although Einstein understood that black holes were mathematical solutions to his equations, he never accepted their physical reality—a viewpoint many shared. This all changed in the 1960s and 1970s, when a deeper conceptual understanding of black holes developed just as new observations revealed the existence of quasars and X-ray binary star systems, whose mysterious properties could be explained by the presence of black holes. Black holes have since been the subject of intense research—and the physics governing how they behave and affect their surroundings is stranger and more mind-bending than any fiction.
After introducing the basics of the special and general theories of relativity, Gubser and his coauthor Pretorius describe black holes both as astrophysical objects and theoretical “laboratories” in which physicists can test their understanding of gravitational, quantum, and thermal physics. From Schwarzschild black holes to rotating and colliding black holes, and from gravitational radiation to Hawking radiation and information loss, the authors use creative thought experiments and analogies to explain their subject accessibly. They also describe the decades-long quest to observe the universe in gravitational waves, which recently resulted in the LIGO observatories’ detection of the distinctive gravitational wave “chirp” of two colliding black holes—the first direct observation of black holes’ existence.
The Little Book of Black Holes takes readers deep into the mysterious heart of the subject.
Steven Gubser is Professor of Physics at Princeton University. His new book follows the acclaimed and popular Little Book of String Theory. Frans Pretorius is Professor of Physics at Princeton University as well.
