What you know
Book 3: Death's End
- Ch 73It is a cube about a kilometer on each side with opposite faces connected, so walking through a wall returns you to the opposite wall; the world is closed and endless.
- Ch 73It is an independent universe with its own time stream, built by Trisolarans as a custom gift; time passes rapidly in the great universe by comparison.
- Ch 73It is a pastoral world with black soil, a white house, trees, a brook, a sun that turns to moon, and columnar robots tending the fields.
- Ch 73When Universe 647 was completed, the Trisolarans had observed no effect of mass loss on the great universe, which was still closed.
- Ch 75The mini-universe had no matter of its own; all its roughly 500,000 metric tons came from the great universe.
- Ch 75The mini-universe is one cubic kilometer, and its space wraps around so objects appear repeated endlessly.
