论文摘要
65年前,约翰·惠勒(John Wheeler)建议,该度量的量子不确定性将在普朗克量表上处于秩序中,从而导致时空几何和拓扑的波动很大,他称其为“时空泡沫”。在这篇综述中,我讨论了实施这一想法的各种尝试,并在理论上和在较小程度上进行观察。
More than 65 years ago, John Wheeler suggested that quantum uncertainties of the metric would be of order one at the Planck scale, leading to large fluctuations in spacetime geometry and topology, which he termed "spacetime foam." In this review I discuss various attempts to implement this idea and to test it, both theoretically and, to a lesser extent, observationally.
