A major problem of quantum field theory in curved spacetime, and quantum gravity more generally, is the lack of sufficient observational and experimental guidance. To address this issue I am proposing to explore various phenomena of semi-classical gravity in table-top experiments. After an introduction to the general mimicking cosmological particle production in parametrically excited Bose-Einstein condensates. Applying classical field methods via the truncated Wigner approximation I will argue that the experimental implementation is within reach. Then, if time permits, I will discuss the possibility of adapting the general principles underlying analogue gravity models to full quantum gravity.
