@suzianne saidUniverse is not a collective noun, which makes it clear that the person who approved of your post is not only as ignorant as you, but as careless of the truth.
"Universe" IS a collective noun, as is "flock" and "population". The members do not have to be identical, nor does there have to be "more than one" of them.
Is English your second language? It's like I'm talking to RJHinds all over again.
From https://www.englishgrammar.org/collective-nouns/:
A collective noun denotes a collection of people, things, animals, emotions or concepts considered as a single whole.
What, pray, is the universe a "collection" of?
From https://www.indiatoday.in/education-today/grammar-vocabulary/story/collective-nouns-305462-2016-01-25:
Collective nouns are considered a subset of countable nouns because they refer to a group of countable nouns as a single unit. Examples: there are 12 eggs in dozen, and there are 52 cards in a deck.
What is universe counting?
This is as differentiated from:
Mass nouns, also referred to as non-countable nouns, signify unbounded amounts, such as liquid, small objects, and abstract or immeasurable concepts. Examples: water, rice, education.
The universe is clearly a mass noun and not a collective noun.
If English is your first language, you're just dumb.
