This study showed for the first time that the evolution of black holes due to the surrounding fields could be
Researchers used a tank simulatorfor water: they made a water funnel similar to the one that forms when you pull out the stopper in the tub. This simulates a black hole, as a wave that comes too close to the sink is drawn into the hole in the plug, unable to escape.
Similar systems in the last decadeare becoming more and more popular as a means of testing gravity phenomena in a controlled laboratory environment. In particular, Hawking radiation was observed in an analog experiment with black holes using quantum optics.
This is how the researchers showed for the first time that ifwaves are sent into an analog black hole, the properties of the black hole itself may change. The mechanism behind this effect in their particular experiment is fairly straightforward to explain. As the waves approach the drain, they push more water into the hole in the plug and cause the total amount of water in the tank to decrease. This leads to a change in the height of the water, which in the simulation corresponds to a change in the properties of a black hole.
The research team is going to use quantum simulators to simulate the extreme conditions of the early universe and black holes.
