Which of the following is true about the time measured during an event by a clock that is traveling with an astronaut in a space craft moving at relativistic speed and an observer who is observing the clock on earth? A. The clock measures proper time in the space craft and observer on earth will measure longer time than the astronaut. B. The clock measures proper time in the space craft and observer on earth will measure a shorter time than the astronaut. C. The clock measures proper time on earth and the astronaut in the space craft will observe a longer time. D. The clock measures proper time on earth and the astronaut in the space craft will observe a shorter time. E. The clock (time) never changes; therefore, both astronaut and observer of earth can measure time accurately irrespective of their location.
