A woman living in galaxy X is about to deliver her first baby. The nearest hospital is in galaxy Y, which is 1.0 x 1012 m away. The woman flew to the hospital in her spaceship at 0.8c. She gave birth one hour after she started flying as timed by her. From the point of view of the nurses at the hospital: i) What was the elapsed time when the woman watch indicated one hour? ii) How far did she travel in that one hour? iii) Was the baby born in the hospital? Justify your answer
