black hole (n.) --> blackhole

I think that "black hole" should be one word: "blackhole" which should be changed through the process of combination. When the two words are separate, it appears as though black is an adjective and hole is the noun that it supports. By combining the two words to make one, this confusion could be eliminated. It also means that the "adjective" black cannot be interchanged with another adjective and still keep its meaning. When I researched this matter on an astronomy website, it explained that the words cannot be capitalized because there is more than one black hole. Please let me know if you see any errors in my reasoning behind making blackhole one word. Thank you!

    I don't think it's necessary to combine them into one word in this case, since holes don't actually have a colour - a (physical) hole is a space. For example, what would "a yellow hole" mean to you?

    EDIT: It's not incorrect to combine them into one word as you suggest, but I can't see how it could improve clarity of meaning.
