时间之箭

A Momentous Arrow of Time

Martin Bojowald

摘要:

量子宇宙学提供了一个独特的阶段来解决与其潜在(也许是真正的量子动力学)意义及其起源有关的时间问题。其中一些问题可以用量子宇宙学的一般方案来分析,另一些问题则最好在圈量子宇宙学中看到。后者的状况仍然不完整,因此尚未出现完整的情况。尽管如此,使用具有渗透到更复杂和更现实的模型的潜力的性质,在这里将描绘一幅模糊的画面。它表明,通过将宇宙遗忘应用于宇宙的早期历史,有可能在一个无意识的理论中推导出一个开端。

英文摘要:

Quantum cosmology offers a unique stage to address questions of time related to its underlying (and perhaps truly quantum dynamical) meaning as well as its origin. Some of these issues can be analyzed with a general scheme of quantum cosmology, others are best seen in loop quantum cosmology. The latter's status is still incomplete, and so no full scenario has yet emerged. Nevertheless, using properties that have a potential of pervading more complicated and realistic models, a vague picture shall be sketched here. It suggests the possibility of deriving a beginning within a beginningless theory, by applying cosmic forgetfulness to an early history of the universe.
