A scientist on the first near-lightspeed ship to Centauri A exchanges letters with his underage girlfriend back on Earth through a wormhole for which time passes at the same rate on both ends. When the ship returns to Earth with its end of the wormhole, the hole will act as a time machine for messages, but the clichéd paradox police won’t let scientist send girlfriend any information about the future.
