We overview the fundamental roles of the de Sitter vacuum in cosmology where it is responsible for powering the early inflationary stage(s) and the present accelerated expansion, in black hole physics where it provides the existence of a wide class of regular black holes and self-gravitating solitons replacing naked singularities, and in particle physics where it ensures the intrinsic relation of the Higgs mechanism with gravity and spacetime symmetry breaking.

德西特真空的基本作用

我们概述了德西特真空在宇宙学中的基本作用，它负责为早期的通货膨胀阶段和当前的加速膨胀提供动力，在黑洞物理学中，它提供了广泛的规则黑洞和自我存在。引力孤子取代了裸奇点，并在粒子物理学中确保了希格斯机制与引力和时空对称性破坏的内在联系。
