意味（1）

A hypothetical system of orbiting solar power satellites meant to completely encompass a star and capture its entire energy output.

意味（2）

(science fiction) A solid shell of matter enclosing a star.

But there's more to a Dyson sphere than collecting solar power. Say you make the sphere one astronomical unit in radius. You've got to clear out the solar system anyway, so you use all the solar planets in the construction. That gives you a shell of, say, chrome steel a few yards thick. Now you put gravity generators all over the shell. You'd have a surface area a billion times as big as the Earth's surface. A trillion people could wander all their lives without ever meeting one another."
