You are in a spaceship moving past Earth at nearly lightspeed and you observe Mort, who is on Earth. You measure his mass, pulse rate, and size. How are they different from the values measured by Mort himself?
A) Mass has decreased, pulse rate has speeded up, and size is reduced along the direction of motion. B) Mass has increased, pulse rate has speeded up, and size is reduced along the direction of motion. C) Mass has increased, pulse rate has slowed down, and size is reduced along the direction of motion. D) They are unchanged, i.e., they are normal. E) Mass has decreased, pulse rate has slowed down, and size is reduced along the direction of motion.
