Sphere

Underwater sci-fi thriller

A sphere is a perfectly round three-dimensional shape—every point on its surface equidistant from the center.

Balls, globes, and bubbles approximate spheres.

The word extends to realms or domains: sphere of influence, outside my sphere of expertise.

In old astronomy, celestial spheres were concentric shells carrying the planets and stars around Earth.

The public and private spheres intersect in unexpected ways.
