Which outcome occurs when a ship's ion thruster approaches lightspeed?

💡 Explanation

Due to mass-energy equivalence, as the ion thruster accelerates, input energy increases its relativistic mass; this outcome limits achievable acceleration despite continual thrust because the thrust acts on increased *inertia*, therefore thrust approaches maximum rather than decreasing efficiency in output.
