The discipline of designing machines, structures, or systems that must operate under the extreme conditions of near-light-speed travel or in regions of intense gravitational fields where relativity is the dominant force. It’s mechanical engineering for a universe where mass increases with velocity, lengths contract, and synchronizing clocks is a philosophical nightmare. Forget steel and bolts; think about containing energies that warp local spacetime.
*Example: Designing the hull of a relativistic starship. At 0.9c, even a speck of interstellar dust hits with the energy of a nuclear bomb. Your shielding isn't just "strong metal"; it might involve creating a forward-facing plasma shield or using a projected magnetic field to ionize and deflect atoms. Also, your onboard computers have to be built from the ground up to handle their own internal signals experiencing time dilation relative to other parts of the ship. It's engineering where the textbook pages are stuck together with space-time curvature.* It's Relativistic Engineering.
