Barnard's Star, a nearby star in our galaxy, is 5.98 light-years away. This means that, as measured by a person on earth, it would take 5.98 years to reach this star. If a rocket leaves for Barnard's Star and travels at a speed of v = 0.925c relative to the earth, by how much will the passenger have aged, in years, according to their own clock, when they reach their destination? Assume that the earth and Barnard's Star are stationary with respect to one another. Round to 3 sig gs
