Suppose that a person is 20.00 y older than their sibling. The person wants to travel outward from Earth for 1.000 y and then back for another 1.000 y (both intervals as they measure them) such that the person is then 20.00 y younger than their sibling when they return. What constant speed parameter B (relative to Earth) is required? (Ignore any effects or delays from turning around).
