The Theory of Relativity has many weird application. Just suppose that everything around you - including your own body - grew to a thousand times its size . . . . would you know? There is no such thing as absolute size. There is no such thing as absolute measurement. You can only comprehend magnitude in relation to other magnitudes.
The same would hold true for contraction. . . . if it took place universally.
But what happens when relativity misses a beat? If one section of the galaxy - one corner of the cosmos expanded or contracted out of proportion to another?
The first experimental hyper-drive space ship blasted off into Deep Space. Time got out of gear. So did the relative proportions of the ship, the crew, and their home world.
What would they find when they returned?
Would they be dwarfs or giants? Or so completely out of proportion that they never fit in again. . . . ?
Above all - could the effect be reversed?
