Which constraint becomes significant as exhaust velocity approaches lightspeed?

💡 Explanation

Relativistic mass increase becomes dominant as predicted by mass-energy equivalence; because, an object's mass increases dramatically with velocity. Therefore extremely more thrust or force on the object is needed to impart a small change, rather than classical predictions.
