Large SciFi universe?

[jekyllsotherhalf]

does anybody know any good books with a vast scifi universe? Like how star wars has a really big universe, even better would be books where the characters travel through a lot of different dimensions.

Maybe The Expanse series? It's been a while since I read but I remember the worldbuilding being very intriguing.

If you want vast, Warhammer 40,000 is massive both in scope and in amount of content.

With well over 100 novels out right now it's the single biggest sci fi universe novel series, and it has an entire galaxy as well as an entire alternate dimension shown.
