A black universe is a nonsingular black hole where, beyond the horizon, there is an expanding, asymptotically isotropic universe. The scalar ﬁeld in our solutions is minimally coupled to gravity, has a nonzero self-interaction potential, while its kinetic energy is negative in a restricted strong-ﬁeld region of space–time and positive outside it. Thus in such conﬁgurations a “ghost” (as are called ﬁelds with negative kinetic energy) is trapped in a small part of space, and this may in principle explain why no ghosts are observed under usual conditions. The conﬁgurations obtained contain diﬀerent numbers of Killing horizons, from zero to four.</abstract><trans-abstract xml:lang="ru">Построены явные примеры глобально регулярных статических сферически- симметричных решений ОТО со скалярным и электромагнитным полями, описывающих кротовые норы (с плоскими и АдС асимптотиками) и регулярные черные дыры, в частности, чёрные вселенные. Чёрная вселенная — это несингулярная чёрная дыра, в которой за горизонтом находится расширяющаяся асимптотически изотропная вселенная. В наших решениях скалярное поле минимально связано с гравитацией и имеет ненулевой потенциал самодействия, а его кинетическая энергия отрицательна в ограниченной области пространства–времени с сильными полями, а вне этой области положительна. Таким образом, в полученных конфигурациях «дух» (этим названием обозначаются поля с отрицательной кинетической энергией) захвачен в малой области пространства, и это в принципе может объяснить отсутствие наблюдаемых «духов» в обычных условиях. Полученные конфигурации содержат разное число горизонтов Киллинга, от нуля до четырёх.</trans-abstract><kwd-group xml:lang="en"><kwd>black holes</kwd><kwd>wormholes</kwd><kwd>nonsingular cosmology</kwd><kwd>phantom matter</kwd><kwd>electromagnetic ﬁeld</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>чёрные дыры</kwd><kwd>кротовые норы</kwd><kwd>несингулярная космология</kwd><kwd>фантомная материя</kwd><kwd>электромагнитное поле</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Komatsu E.
