Explanation:

  • The distance between the Moon and the Earth can be measured by the person either by sending a light pulse or by using a metre scale.
  • As we know, when the metre scale is used, there will be the contraction of length in a relatively affecting frame.
  • Consequently, more than the actual distance, this distance will be lesser. On the contrary, the time difference between the reception and the emission is observed on using a light pulse.
  • It is to be understood that there will be a dilation of time in the moving frame. So, in this case, the measured difference will be greater.
  • So, more than the actual distance, the measured distance can either be larger or smaller, but it can never be the same.
