Over the last decade the physics of black holes has been revolutionized by developments that grew out of Jacob Bekenstein s realization that black holes have entropy. Stephen Hawking raised profound issues concerning the loss of information in black hole evaporation and the consistency of quantum mechanics in a world with gravity. For two decades these questions puzzled theoretical physicists and eventually led to a revolution in the way we think about space, time, matter and information. This revolution has culminated in a remarkable principle called The Holographic Principle , which is now a major focus of attention in gravitational research, quantum field theory and elementary particle physics. Leonard Susskind, one of the co-inventors of the Holographic Principle as well as one of the founders of String theory, develops and explains these concepts.
From the viewpoint of the Fidos, a particle is injected into the system at $\omega = -\infty$ and $\rho = 0$. The particle travels to some distance and then falls back towards $\rho = 0$ and $\omega = +\infty$. Thus, according to the Fidos, the fluctuation lasts for an infinite time and is therefore not virtual at all. (查看原文)
