Eureka! Scientists explore mysteries of black holes with hi-tech bathtub

Nottingham University researchers are simulating black holes with a tiny vortex inside a bell jar of superfluid helium

At the end of a nondescript corridor at the University of Nottingham is a door labelled simply: Black Hole Laboratory. Within, an experiment is under way in a large, hi-tech bathtub that could offer a unique glimpse of the laws of physics that govern the real thing.

The lab is run by Prof Silke Weinfurtner, a pioneer in the field of analogue gravity, whose work has demonstrated uncanny parallels between the mathematics describing fluid systems on Earth and some of the most extreme and inaccessible environments in the universe.
