虫洞与黑洞能否通过放大效应加以区分?

Can wormholes and black holes be distinguished by magnification?

Ke Gao, Lei-Hua Liu

AI总结:

本文通过旋转 Simpson-Visser 度规计算光线偏折与放大效应,发现 Ellis-Bronnikov 虫洞仅有单放大峰而 Kerr 黑洞可有一至三个放大峰,从而为区分虫洞与黑洞提供依据。

摘要:

虫洞和黑洞的放大效应已被广泛研究。为了更好理解这一放大现象,提供有限距离分析至关重要。本文选取旋转 Simpson-Visser 度规(RSV)作为研究重点。通过计算 RSV 度规中光线的偏折,我们确定了由此产生的放大效应,然后将 RSV 度规应用于 Ellis-Bronnikov 虫洞、Schwarzschild 黑洞和 Kerr 黑洞(或虫洞)等具体例子来分析放大效应。我们发现 Ellis-Bronnikov 虫洞只有单个放大峰,而 Kerr 黑洞具有一到三个放大峰。此外,本文的研究结果表明,银河系中心黑洞的透镜效应表现出多峰放大。然而需要指出的是,这些效应无法从地球上观测到。

英文摘要:

The magnification effect of wormholes and black holes has been extensively researched. It is crucial to provide a finite distance analysis to understand this magnification phenomenon better. In this article, the rotational Simpson-Visser metric (RSV) is chosen as the focus of research. By calculating the deflection of light in RSV metric, we determine the resulting magnification effect, then applied the RSV metric to specific examples such as the Ellis-Bronnikov wormhole, Schwarzschild black hole, and Kerr black hole (or wormhole) to analyze the magnification. We find that Ellis-Bronnikov wormhole only has single magnification peaks, while Kerr black hole has one to three magnification peaks. In addition, the article's findings suggest that the lensing effect of the Central Black Hole of the Milky Way Galaxy exhibits magnification of multiple peaks. However, it should be noted that these effects are not observable from Earth.
