Explore the fascinating world of physics as scientists create a universe in a box and simulate black holes to study phenomena we cannot directly observe.
Inside Silke Weinfurtner’s Gravity Laboratory at the University of Nottingham, her team simulates some of the most extreme phenomena in the cosmos, using superfluid helium, including black holes and, even, the entire universe in a search for quantum gravity.
Mechanical vibrations in one experiment create fluid flows that mimic spacetime around a rotating black hole. And the newer ICE experiment simulates the rapid expansion of the primordial universe. Weinfurtner’s toy universe is underpinned by similar mathematics to these otherwise inaccessible phenomena, allowing inferences to be drawn about how black holes and the early universe behave. In particular, her team can explore how space-time behaves in realms where quantum effects also come into play, which they hope will offer clues towards a long-sought theory of quantum gravity.
