Scientists at the University of Nottingham are using a hi-tech bathtub setup to explore the mysteries of black holes. The experiment, led by Prof Silke Weinfurtner, involves studying the mathematical parallels between fluid systems on Earth and the extreme environments of black holes. The team has previously investigated Hawking radiation and is now working on a more advanced simulator to gain further insights into black hole behavior.

While some critics question the value of fluid systems in understanding cosmological processes, Weinfurtner remains optimistic about the potential of analogue gravity experiments.
