Captain Katherine Janeway takes off from Earth and moves at speed 0.96c toward the star Sirius, which is 8.6 ly distant. a) How much time will have elapsed by Earth clocks when Captain Janeway reaches Vega? b) How much time will have elapsed by Earth clocks when Earth observers receive word (sent by a radio signal) from Captain Janeway that she has arrived? c) How much older will Earth observers calculate the Captain to be (measured from her frame) when her message reaches them on Earth than she was when she started the trip?
