Research

We are carrying out research in the field of gravity simulators for early universe and black hole processes. For this we have identified and developed a series of novel experiments focussing on the control, manipulation and detection of fluid and superfluid interfaces. The experimental efforts are paired with high-level modelling support to reproduce in the laboratory some of the most ill-understood processes in our Universe, and make concrete predictions, transferable to cosmology, astrophysics and fundamental physics.

Outreach

The combination of deep fundamental-science goals and cutting-edge technology puts us in a natural position to communicate to the general public the excitement and importance of fundamental research. For example, the Black Hole Laboratory in Nottingham has been filmed for the Strip of Cosmos (Discovery channel) and Black Holes - The Edge of All We Know (Netflix) science documentaries. We are currently planning a variety of novel outreach activities. Follow the link below to learn more about our outreach programme and/or to get involved.
