the universe is mostly nothing, badly lit, and somehow still showing up for work.
means Everything that exists — all space, time, matter, and energy — taken together as a single whole.
from From Latin universum, the neuter of universus, 'all together, whole,' which breaks down into unus ('one') and versus, the past participle of vertere ('to turn'). So the literal sense is 'turned into one' — the entire scattered cosmos rolled up and treated as a single thing. It reached English through Old French univers.
