SUMMARY
The discussion focuses on calculating the relativistic mass of a man weighing 78 kg on Earth while traveling at 0.93c. The correct formula used is M = Mo / √(1 - v²/c²), where Mo is the rest mass and v is the velocity. The calculation yields a relativistic mass of approximately 212.2 kg. The forum participants confirm the use of this formula and clarify the distinction between weight and mass in the context of relativity.
