Baron replied, As far as we know, it’s not possible for a person to move at twice the speed of light. In fact, it’s not possible for any object with the kind of mass you or I have to move faster than the speed of light. Sam Baron, “Curious Kids: what would happen if someone moved at twice the speed of light?” at The Conversation (May 24, 2022) He explains why not as follows, To accelerate an object with mass, we have to add energy. The faster we want the object to Read More ›
