论文摘要
我们努力说明将其应用于引力理论的不同重要问题的陆地原则的物理相关性。我们将首先在一般相对论的背景下进行分析，从Landauer原理暗示的事实所带来的后果，该信息具有质量。接下来，我们将分析Landauer原则所起的作用，以了解为什么观察者的不同一致性提供了对同一空间时间的非常不同的物理描述。最后，我们将把陆地原理应用于重力辐射问题。我们将看到，重力辐射是一个不可逆转的过程，需要消散，这是陆路原理的直接结果，也是引力辐射传达信息的事实。测量辐射能量部分的表达式应与辐射信息和定义该过程中删除的位总数的表达，以及将后者与邦迪新闻函数联系起来的显式表达式。
We endeavour to illustrate the physical relevance of the Landauer principle applying it to different important issues concerning the theory of gravitation. We shall first analyze, in the context of general relativity, the consequences derived from the fact, implied by Landauer principle, that information has mass. Next, we shall analyze the role played by the Landauer principle in order to understand why different congruences of observers provide very different physical descriptions of the same space--time. Finally, we shall apply the Landauer principle to the problem of gravitational radiation. We shall see that the fact that gravitational radiation is an irreversible process entailing dissipation, is a straightforward consequence of the Landauer principle and of the fact that gravitational radiation conveys information. An expression measuring the part of radiated energy that corresponds to the radiated information and an expression defining the total number of bits erased in that process, shall be obtained, as well as an explicit expression linking the latter to the Bondi news function.
