霍金辐射通常被直观地想象为穿过视界的粒子。然而，乍一看，障碍在哪里并不明显。在这里，我表明势垒取决于隧穿粒子本身。关键是要实现能量守恒，使黑洞在辐射过程中收缩。一个直接的结果是，辐射光谱不能是严格的热。对热谱的修正，正是人们从基础的幺正量子理论中所期望的形式。这可能对黑洞信息之谜产生深远的影响。
Hawking radiation is often intuitively visualized as particles that have tunneled across the horizon. Yet, at first sight, it is not apparent where the barrier is. Here I show that the barrier depends on the tunneling particle itself. The key is to implement energy conservation, so that the black hole contracts during the process of radiation. A direct consequence is that the radiation spectrum cannot be strictly thermal. The correction to the thermal spectrum is of precisely the form that one would expect from an underlying unitary quantum theory. This may have profound implications for the black hole information puzzle.
