This pedagogical introduction to the physics of black holes emphasizes the “membrane paradigm”, which translates the mathematics and physics of black holes into a form accessible to readers with little knowledge of general relativity but a solid grounding in nonrelativistic physics. This is accomplished without resort to approximations or loss of content. Instead of treating a black hole’s “event horizon” as a globally defined null surface in four-dimensional space time, the paradigm views it as a two-dimensional membrane in three-dimensional space. Made of viscous fluid, electrically charged and conducting, with finite entropy and temperature but no power to conduct heat, this membrane is seen as having familiar properties that enable the reader to understand intuitively and compute quantitatively the behavior of black holes in complex astrophysical environments.
Kip Stephen Thorne is an American theoretical physicist and writer known for his contributions in gravitational physics and astrophysics. Along with Rainer Weiss and Barry C. Barish, he was awarded the 2017 Nobel Prize in Physics for his contributions to the LIGO detector and the observation of gravitational waves. A longtime friend and colleague of Stephen Hawking and Carl Sagan, he was the Richard P. Feynman Professor of Theoretical Physics at the California Institute of Technology (Caltech) until 2009 and speaks of the astrophysical implications of the general theory of relativity. He continues to do scientific research and scientific consulting, most notably for the Christopher Nolan film Interstellar.
Quite nice, majority of theories is well explained and should not cause any difficulties for people who have nothing in common with this particular field of science. I recommend it!
