We revisit such ideas, using features associated with a negative cosmological constant and asymptotically AdS boundaries to strengthen the results, introduce a change in perspective, and connect with recent replica wormhole discussions of the Page curve. A key new feature is an emphasis on the role of null states. We explore this structure in detail in simple topological models of the bulk that allow us to compute the full spectrum of associated boundary theories.

This quote from Kip Thorne, emeritus professor of theoretical physics at Caltech and part-winner of the Nobel Prize for Physics, begins a biographical memoir of Stephen Hawking published by the Royal Society earlier this year [1]. It is difficult to think of a better way to sum up his scientific achievements. Few individuals can have done more to further our understanding of the Universe we live in, and when his work raises questions, these will be seen as stepping-stones to a deeper understanding. His extensive publications form a permanent record of how his ideas evolved; this collection of papers from Physics Letters B PLB is part of that record. The work for his doctoral thesis was also published in a series of remarkable papers.

Black Holes and Baby Universes and Other Essays

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. Hawking also describes his life when he was young, and his later experience of motor neurone disease. The book also includes an interview with Professor Hawking.

In his phenomenal bestseller A Brief History of Time, Stephen Hawking literally transformed the way we think about physics, the universe, reality itself. In these thirteen essays and one remarkable extended interview, the man widely regarded as the most brilliant theoretical physicist since Einstein returns to reveal an amazing array of possibilities for understanding our universe. With his characteristic mastery of language, his sense of humor and commitment to plain speaking, Stephen Hawking invites us to know him better—and to share his passion for the voyage of intellect and imagination that has opened new ways to understanding the very nature of the cosmos.

Hawking has recently pointed out that black holes cannot evaporate and disappear through wormholes because the entropy of a baby universe would not equal its size squared times some proportionality constant. In this report it is shown that multiply connected Euclidean wormhole spacetimes can be associated with nonlinear dynamic laws which are analogous to those of nonequilibrium thermodynamics, making plausible a full generalization of thermodynamics encompassing both nonequilibrium and gravitational effects. It is seen that both at equilibrium and out of it baby universe thermodynamics can provide the right relation between the size of the originating black hole and its entropy.

ГЛАВА 51 Джабба был похож на гигантского головастика. Подобно киноперсонажу, в честь которого он и получил свое прозвище, его тело представляло собой шар, лишенный всякой растительности. В качестве штатного ангела-хранителя компьютерных систем АН Б Джабба ходил по отделам, делал замечания, что-то налаживал и тем самым постоянно подтверждал свое кредо, гласившее, что профилактика-лучшее лекарство. Ни один из поднадзорных ему компьютеров АНБ не заразился вирусом, и он был намерен не допустить этого и впредь. Рабочим местом Джаббы была платформа, с которой открывался вид на подземную сверхсекретную базу данных АНБ. Именно здесь вирус мог бы причинить наибольший ущерб, и именно здесь Джабба проводил большую часть времени.

Программное обеспечение ТРАНСТЕКСТА по раскрытию кодов должно храниться в Федеральной резервной системе и министерстве юстиции. Это должно было гарантировать, что АНБ не сможет перехватывать частную переписку законопослушных граждан во всем мире. Однако когда настало время загрузки программного обеспечения, персоналу, работавшему с ТРАНСТЕКСТОМ, объявили, что планы изменились. В связи с чрезвычайной обстановкой, в которой обычно осуществляется антитеррористическая деятельность АНБ, ТРАНСТЕКСТ станет независимым инструментом дешифровки, использование которого будет регулироваться исключительно самим АНБ. Энсей Танкадо был возмущен. Получалось, что АНБ фактически получило возможность вскрывать всю почту и затем пересылать ее без какого-либо уведомления. Это было все равно что установить жучки во все телефонные аппараты на земле.

К клубу вела узкая аллея. Как только он оказался там, его сразу же увлек за собой поток молодых людей. - А ну с дороги, пидор! - Некое существо с прической, больше всего напоминающей подушечку для иголок, прошествовало мимо, толкнув Беккера в бок. - Хорошенький! - крикнул еще один, сильно дернув его за галстук. - Хочешь со мной переспать? - Теперь на Беккера смотрела юная девица, похожая на персонаж фильма ужасов Рассвет мертвецов.

 - Нужен код. - Код? - сердито переспросила. Она посмотрела на панель управления. Под главной клавиатурой была еще одна, меньшего размера, с крошечными кнопками. На каждой - буква алфавита.

Сьюзан плюхнулась обратно в ванну. - Ох! - Она не могла скрыть разочарование.  - Здравствуйте, шеф.
