Twins Jack and Jill are initially at rest at x=L/2 in IRF K. Jill travels to the Origin at speed v, and Jack travels to x=L at the same speed. They are still the same age. At some pre-arranged time each twin ignites a rocket and begins accelerating in the positive x direction. Each twin shuts the thruster down at a later, pre-arranged time. They simultaneously come to rest in IRF K’, traveling in the +x direction of K at speed v>0. They decide to come together again, traveling toward one another at the same speed v relative to K’. Relative to K, Jill must travel faster than v and Jack must travel slower than v. When they get together again, Jack has aged less than Jill. Comments?
