QMAF (Quantum Mechanical Amniotic Fluid)
Ships that travel into deep space house their occupants in a tank filled with QMAF. A dense Perfluorocarbon, it provides a breathable radiation shield saturated with proteins, carbohydrates, urea, and aiding nanos.
Additionally, all atoms within the QMAF are stimulated to transmit data. It develops a psychic connect between pilot and ship. No displays. No controls. Just two minds operating in a semi-conscious dream.
