The property of GERMAIN ROUSSEAUX resembles a very long and extremely narrow fish tank. There is a plastic ramp in the middle of the bottom. When he turns on the machine, the waves go along the tank and accelerate as they cross the ramp. A black hole, according to him.
Nah, not a true black hole either. No gaping hole in space-time ready to devour stars. The experiment conducted by Rousseaux at the Institut Pprime in Poitiers, France, is a physical model of how black holes’ enormous gravity may suck in waves (often light waves, but in this instance water waves) so that they can’t escape.
It’s a “gravity analogue,” a term used in the industry, and it’s far from the only one. Despite the mutterings of many theorists, who are sceptical that such modest tests can teach us anything about the universe’s darkest, most enigmatic things, researchers have built scores of these tabletop models over the past 15 years.
However, recently scientists have begun to replicate ever more of the universe, including the entire embryonic universe itself. Now, some of them think the models are revealing truths about the universe. Even the cherished constant of physics, the speed of light, has been called into question. According to Rousseaux, “implementing findings from these models would require a paradigm shift.” But do we really have to rely on tanks of liquid to explain the cosmos?
It’s likely that there are plenty more riddles like this out there, and that researchers are always looking for answers. Researchers are exploring a wide variety of methods to probe the physics of black holes and other anomalies, including gravity analogues like the one developed by Germain Rousseaux.
Some theorists were sceptical at first, but these desktop simulations have now shown to be rather accurate. Researchers can learn about the effects of gravity on light waves near a black hole by, for instance, observing the behaviour of waves in a tank of liquid. The increasing complexity of these models allows us to get fresh insights into some of physics’ most fundamental puzzles.
In conclusion, it may seem implausible that something as mundane as a tank of liquid may aid us in deciphering the mysteries of the cosmos, but the success of gravity analogues and other physical models shows we should not discount their potential. We may be able to solve some of the greatest mysteries of our time if we keep digging into these models and testing the limits of our knowledge.
