Space or outer space isn’t a term commonly used in cosmology which is the field of study of the chronology and evolution of the universe.
And in this context it makes perfect sense within 1b light years we can observe the universe as it is more or less in its current state, so looking at something 100 light years away or 1b isn’t that different. Once you go past that line you begin to go further and further in time so different stages within the evolution of the universe take precedence over local phenomena.
It doesn’t indicate that there are other universes out there just due to the speed of light what we can observe can be drastically different than what is around us as well as what is actually going anywhere else at the current age of the universe.
This of course has nothing to do with the popular scifi concept of parallel universes.
Both have their usefulness when conducting observations as we need to take certain assumptions based on what we know.
The former is anything that is currently within our cosmological horizon the latter is anything we can observe that is in the same relative slice of time or cosmological development stage as us.
The term "nearby universe" is perfectly fine, as far as the English language goes.
This doesn't sound like standard English either, though.

Hot singles in a nearby area would make sense
Hot singles in your nearby area doesn't make sense, because it is unclear what the intention of the word "nearby" is. It clearly modifies "area". So the area is nearby something. By what is it nearby?
If we go with the single analogy it would be like filtering on Tinder based on distance as well as when the last time that account was active.
It’s like if going more than 50 miles further out of your existing location would only show tinder accounts from 5 years ago which wouldn’t be relevant for what you are looking for which are people who are single right now and looking right now.
I wasn't using the word "area", though.

Not according to my language sensibility at the very least. Just like sibling comment's remark about "nearby house" when talking about the very house you're currently in.
¹ Let's leave for now what "class" means for programmers vs. other kinds of people.
The multiverse and other theories of multiple universes nominally belong to other fields of study.
Cosmology is the study of the universe we live in, specifically it’s development.
That’s why we have terms such as the local/near by universe and the observable universe. I find odd that none that that seem to take offense with the former mentions the latter, since grammatically they are identical.
