它表明，重力波的流动流体在一个浅盆可以用来模拟黑洞周围的现象在实验室中。由于重力波的速度以及它们的高波数色散（亚光速与超光速）可以通过改变流体的高度（及其表面张力）来轻松调整，因此这种情况相对于声波和介电黑洞类似物具有某些优势，例如，尽管它在测试量子效应方面的用途是可疑的。它可以用来研究各种经典的不稳定性与黑（和白色）洞的实验，包括积极和消极的范数模式混合的视野。
It is demonstrated that gravity waves of a flowing fluid in a shallow basin can be used to simulate phenomena around black holes in the laboratory. Since the speed of the gravity waves as well as their high-wave-number dispersion (subluminal vs superluminal) can be adjusted easily by varying the height of the fluid (and its surface tension) this scenario has certain advantages over the sonic and dielectric black hole analogs, for example, although its use in testing quantum effects is dubious. It can be used to investigate the various classical instabilities associated with black (and white) holes experimentally, including positive and negative norm mode mixing at horizons.
