The universe is a big word — in fact, it includes all matter and all of space.
We can't see or know much about the outer limits of the universe, but we know that it has them, and the idea of matter contained within boundaries gives us other meanings for the word. You might refer to a "universe of ideas," or when conducting a scientific study, create "a universe of data." Universe can also mean a defined set of something — the five blocks between the playground and home can be the whole universe for a small child.
