论文摘要
一般相对论用时空的几何形状描述了引力。它预测了拉伸和压缩时空的引力波（GWS）的存在，并通过最新的干涉仪观测来检测到。但是，对于那些不熟悉一般相对论的人来说，可能很难理解GWS实际上如何伸展和压缩时空。在本文中，在审查了GW的影响可以理解为牛顿力学中的力量之后，我们考虑了极端且容易可感知的情况，在这种情况下，大振幅GWS经过人体和地球，并证明GW会导致回到近距离平原在日常生活中通常发生的现象。我们的分析提供了智力和教学材料，以理解一般相对论中无人物的GW的性质。
General relativity describes gravitation in terms of the geometry of spacetime. It predicts the existence of gravitational waves (GWs) that stretch and compress spacetime and were detected recently by state-of-the-art interferometer observations. Yet, for those who are not familiar with general relativity, it may be difficult to understand how the GWs actually stretch and compress spacetime. In this paper, after reviewing the fact that the effects of GWs can be understood as a force in Newtonian mechanics, we consider extreme and readily perceivable situations where large-amplitude GWs pass through the human body and the Earth, and demonstrate that GWs cause phenomena that commonly occur in daily life by back-of-the-envelope calculations. Our analysis provides intellectual and pedagogical materials for understanding the nature of GWs for nonexperts in general relativity.
