If you like stories of science fiction, I'm surprised no-one mentioned Greg Egan.

"Singleton": what if many-worlds interpretation of quantum theory was real?

The Orthogonal trilogy, starting with "The Clockwork Rocket": what if space-time was Riemannian rather than Lorentzian? Physics explained at https://www.gregegan.net/ORTHOGONAL/00/PM.html

Greg Egan can write character-based science fiction when he wants to as well (you can find it in his short stories), but it has to be a topic that resonates with him personally. Without a resonance, the stories often look like "plausible vignette - fast-forward through technological implications - another plausible vignette with characters already changed by the experience".

		I think he exceeds at doing both at once. One of the things I loved most about The Clockwork Rocket wasn't the exploration of a universe unlike our own - to be honest, most of it went over my head - but the characters dealing with very human issues in a very non-human world. Dichronauts is very similar; in a universe with a slight tweak to the laws of physics, we spend most of the book exploring the consequences of that tweak, but also the experiences of the characters living in it, some of which are a consequence of their world, and some of which feel like situations we could very easily find on our planet.
