I have no advice, but this is a very powerful way of looking for solutions. Today I ran into some physics postdocs at the skatepark. They told me about their research doing fluid mech experiments to simulate the behaviour of space near but not in a black hole. One of them (Sam) wrote his highly entertaining PhD thesis about the analogy of a draining bathtub's vortex with black holes https://arxiv.org/abs/2009.02133 https://arxiv.org/abs/2009.02133
