摘要：

我给一个全息假说，它假定一个宇宙的重力可以描述的量子场论在更少的维度的批判性审查。我首先回忆起这个想法是如何起源于对黑洞热力学的考虑，以及当考虑到霍金辐射时出现的所谓信息悖论。弦量子引力试图用AdS/CFT对应来解决这个难题，根据这个对应，一个在5维反德西特空间中的黑洞就像一个由粒子和辐射组成的平坦的4维场。虽然这种有趣的全息性质，也被称为规范/引力对偶性，从未被严格证明，但它推动了核物理、凝聚态物理、广义相对论和宇宙学等不同领域的许多研究计划。最后，我讨论了全息猜想的利弊，并强调了黑洞在理解量子引力和理论物理学遥远领域之间可能的对偶性方面所起的关键作用。

英文摘要：

I give a critical review of the holographic hypothesis, which posits that a universe with gravity can be described by a quantum field theory in fewer dimensions. I first recall how the idea originated from considerations on black hole thermodynamics and the so-called information paradox that arises when Hawking radiation is taken into account. String Quantum Gravity tried to solve the puzzle using the AdS/CFT correspondence, according to which a black hole in a 5-D anti-de Sitter space is like a flat 4-D field of particles and radiation. Although such an interesting holographic property, also called gauge/gravity duality, has never been proved rigorously, it has impulsed a number of research programs in fields as diverse as nuclear physics, condensed matter physics, general relativity and cosmology. I finally discuss the pros and cons of the holographic conjecture, and emphasizes the key role played by black holes for understanding quantum gravity and possible dualities between distant fields of theoretical physics.
