history
宙 classically meant all of time, while 宇 meant all of space. Together 宇宙 literally fuses 'all space and all time' into the modern word for the universe.

Components

radical
宀 mián
roof; house
The roof radical 宀 frames 宙 as a vast covering vault, here the all-enclosing span of time.
phonetic
由 yóu
from; cause
由 sits under the roof and provides the sound element (drifted from yóu to zhòu); it carries no meaning of its own here.
