时间非对称时空结构的性质和起源

The Nature and Origin of Time-asymmetric Spacetime Structures

H. D. Zeh

摘要:

时间非对称时空结构,特别是那些代表黑洞和宇宙膨胀的时空结构,与其他时间箭头密切相关,如第二定律和辐射延迟。量子箭的性质,通常归因于波函数的坍缩,是必不可少的,特别是为了理解讨论得很多的“黑洞信息损失悖论”。然而,这种悖论呈现出一种新的形式,并且可以通过一种前后一致的因果关系处理方法来避免,这种因果关系处理方法可能能够避免视界和奇点。- 一个“主箭头”,它结合了所有的时间箭头,不需要与正式的时间参数,用于制定动态作为一系列的全球性的状态(配置或希尔伯特空间的轨迹)的方向确定。如果宇宙膨胀参数被正式扩展到未来的收缩时代或负的“大爆炸前”值,它甚至可能改变相对于基本物理时钟的方向,如宇宙膨胀参数。

英文摘要:

Time-asymmetric spacetime structures, in particular those representing black holes and the expansion of the universe, are intimately related to other arrows of time, such as the second law and the retardation of radiation. The nature of the quantum arrow, often attributed to a collapse of the wave function, is essential, in particular, for understanding the much discussed "black hole information loss paradox". However, this paradox assumes a new form and can possibly be avoided in a consistent causal treatment that may be able to avoid horizons and singularities. - A "master arrow", which combines all arrows of time, does not have to be identified with a direction of the formal time parameter that serves to formulate the dynamics as a succession of global states (a trajectory in configuration or Hilbert space). It may even change direction with respect to a fundamental physical clock such as the cosmic expansion parameter if this was formally extended either into a future contraction era or to negative "pre-big-bang" values.
