Physics says a spacecraft with mass can never reach the speed of light: as it accelerates closer to c, the energy required rises without limit, so light speed isn’t merely difficult to reach — for massive objects, it’s physically unattainable.
A powerful enough engine can make a spacecraft move faster and faster. That familiar sentence contains a trap:…
