利用引力波散射寻找虫洞

Searching for wormholes with gravitational wave scattering

Shou-shan Bao, Shaoqi Hou, Hong Zhang

摘要:

连接宇宙中遥远地方的虫洞是广义相对论的著名解。特别是,允许星际旅行的可穿越虫洞在科幻小说中也很受欢迎。然而,目前还没有发现它们存在的迹象。在这项工作中,我们提出了使用引力波(GW)的散射球形虫洞来寻找它们的存在。我们仔细计算了反射和透射波形与时间无关的散射理论。我们的研究结果定量地显示了虫洞两侧两个宇宙中的回声特征。在一定的虫孔质量范围内,透射波具有独特的孤立啁啾,没有螺旋波形,反射波具有反啁啾行为,即,啁啾信号的丢失。我们还计算了目前和计划中的GW望远镜的搜索范围。我们的方法可以适用于有效地计算模板搜索虫洞。

英文摘要:

Wormholes bridging distant places of the universe are well-known solutions of general relativity. In particular, traversable wormholes which allow interstellar traveling are also popular in science fiction. However, no hint of their existence has been found yet. In this work, we propose using the gravitational wave (GW) scattering off spherical wormholes to search for their existence. We carefully calculate the reflected and transmitted waveforms with time-independent scattering theory. Our results quantitatively show the echo signatures in the two universes on both sides of the wormhole. In a certain wormhole mass range, the transmitted wave has a unique isolated chirp without an inspiral waveform, and the reflected wave has the anti-chirp behavior, i.e., the missing of the chirping signal. We also calculate the searching range of the current and projected GW telescopes. Our method can be adapted to efficiently calculate the templates to search for wormholes.
