Exploring exotic and interesting ideas is usually fun for the writer. And it can be fun for the reader too, if done well, because it engages the reader in an intellectual level ( [No suprise there's a whole SE for that][1]No suprise there's a whole SE for that ).
I'm reminded of China Miéville's "[Perdido Street Station][2]""Perdido Street Station": it's a really great book with a really original setting, but the author has the habit of starting almost each chapter with a long description of how the streets of the main city look like, where are the squares, how building looks. He's very good at doing it, but personally in some chapter towards the end I just wanted to see the plot unfold. On the other hand, the friend who suggested the book to me enjoyed those descriptions wholly, so to each their own.
You may want to explore differents formats. I see those "unscientific science" descriptions that you talk about more suited to short stories (as I said, it's not unheard of in the sci-fi genre). In
In a short story - almost like a scientific article - you could dissect an idea without boring the readers, in a format like "What if x - then y". Longer Longer formats, like novels, will probably require a plot able to stand on its own. [1]:
Some authors do include pieces of "scientific like" description of non-existant things. In the https://worldbuilding.stackexchange.com/questions [2]:Thirteen lives and a half of capitan Bluebear, Walter Moers inserts encyclopedia pages describing creatures of the world. Are they relevant to the plot? Eh, not really. In Ensel and Krete, it gets even worse! I've also seen some italian authors do this https://en.wikipedia.org/wiki/Perdido_Street_Station(in parody and satirical genres, like Stefano Benni's works).
