This book is a collection of essays and lectures written by Hawking, mainly about the makeup of black holes, and why they might be nodes from which other universes grow. Hawking discusses black hole thermodynamics , special relativity , general relativity , and quantum mechanics .
In the final chapter, Thorne delves into even more speculative matters relating to black hole physics, including the existence and nature of wormholes and time machines. [1] The book features a foreword by Stephen Hawking and an introduction by Frederick Seitz. In addition to the main text, the book provides biographical summaries of the major ...
A Brief History of Time: From the Big Bang to Black Holes is a book on theoretical cosmology by the physicist Stephen Hawking. It was first published in 1988. It was first published in 1988. Hawking wrote the book for readers who had no prior knowledge of physics.
Black Holes, Wormholes and Time Machines is a book by physicist Jim Al-Khalili, published in 1999. Al-Khalili talks about a range of modern science topics, from geometry to the theory of relativity. [1] [2] [3] [4]
In 1993, he described the Wald entropy of a black hole, which is dependent simply on the area of the event horizon of the black hole. [12] He organized The Symposium on Black Holes and Relativistic Stars in 1996, in honor of the late Nobel Prize-winning theoretical astrophysicist Subrahmanyan Chandrasekhar.
He used the term black hole in 1967 during a talk he gave at the NASA Goddard Institute of Space Studies (GISS), [72] although the term had been used earlier in the decade. [ a ] Wheeler said the term was suggested to him during a lecture when a member of the audience was tired of hearing Wheeler say "gravitationally completely collapsed object".

The Black Hole Era is defined as "40 < n < 100". In this era, according to the book, organized matter will remain only in the form of black holes. Black holes themselves slowly "evaporate" away the matter contained in them, by the quantum mechanical process of Hawking radiation. By the end of this era, only extremely low-energy photons ...
