Scientists from the University of Nottingham have unveiled new insights into the behavior of black holes by mimicking one of the space giants in a water tank.
New research team paper, published in Corporate Review Letters, describing what they would look like in a phenomenon called backreaction.
In doing so, they are the first study to show how the evolution of black holes, based on the fields around them, can resemble a laboratory.
The researchers used a tank simulator made up of a drainage vortex to image a black hole. In much the same way that water drains when you leave a tank, any wave that comes too close to the drain will be dragged down the plug.
Using this method, the researchers showed that when waves are inserted into an analog black hole, the properties of the black hole can change dramatically.
The reason for this is surprisingly simple: when waves come close to the drain, they effectively push more water down the crane causing the amount of water in the tank to decrease. .
This causes a change in the height of the water, which corresponds to a change in the properties of the black hole, according to the obvious rules of simulation of the researchers.
Analog black holes are ‘basic retrospective systems’
“For a long time, it was not clear whether the reversal would bring about any measurable changes in analog systems where the fluid flow is controlled, for example, using a water pump. We have proven that analog black holes, like their gravity counterparts, closely retrospective systems, “lead author Dr. Sam Patrick, from the University of Nottingham School of Mathematical Sciences, explains in a press release.
“We have shown that moving waves in a drainage bath push water down the plug hole, dramatically changing the drainage speed and as a result changing the effective gravity attraction of the analog black hole,” he said. follow.
The researchers say their results will be crucial for future experiments. For example, this type of interaction will be “crucial for studying the evacuation of black holes in the laboratory,” explains Dr Patrick.
The University of Nottingham recently received a funding increase of £ 4.3 million ($ 5.8 million) for black hole research: the research team aims to use quantum simulators to identify global conditions and, in doing so, discover the mysteries of the cosmos.
