There are a pair of identical twins. One remains on earth while the other goes on an extended trip through the galaxy. During this trip, the traveler averages a speed of 0.95 times the speed of light. If this trip lasts for a period of one year, as measured by the traveler, what is the age difference between the twins when the traveler returns to earth?
