  In this paper we will investigate how one can create emergent curved
spacetimes by locally tuning the coupling constants of condensed matter
systems. In the continuum limit we thus obtain continuous effective quantum
fields living on curved spacetimes. In particular, using Stingnet condensates
we can obtain effective electromagnetism. We will show for example how we
obtain quantum electrodynamics in a blackhole (Schwarzschild) spacetime.
