A Cook(narrator)(sound exactly like Paul Giamatti) on a ship traveling at light-speed. this is a experimental spaceship studying faster than light travel. he is the only one on board that he is aware of. something weird happened when they hit light speed. everyone vanished and navigation is not responding. outside the ship is just blackness. He starts going crazy and imagines a woman or wife is there with him.
  found the short story on a free audio book app. I think i was once a radio-broadcast short story.
