1947 Thrilling Wonder Stories Feb. 100/2	How about having Leinster write a sequel concerning life on the inside of a pocket universe.

1984 I. Asimov et al. Isaac Asimov Presents Best Sci. Fiction Firsts 95	Heinlein cleverly arranged for the crew to be ignorant of the ship's original purpose, going so far as to create a ‘pocket universe’ in which the people involved did not even know they were on a ship.
