• Resumen

  • Various sources1–9 claim that objects move through space-time at the speed of light, or similar language. Many students and some teachers hear that phrase and have an incorrect mental image of what it means. We refute that claim, arguing it results from misinterpreting the relativistic 4-velocity of special relativity.
