Hello, Year 2250

Hard Sci-Fi, Interstellar Travel or Drifting, and Alien Civilizations

I don't like stories that are constantly at war, fighting from beginning to end, from the Solar System all the way to the Milky Way. I prefer nuanced portrayals of alien societies and storylines, as if observing another civilization.

Pure Science Fiction: No Fantasy, Games, Movies, or Awakening

A Technological Universe, From One to Ten Dimensions and From Level-One to God-Tier Civilizations

From Earth to the Solar System → the Local Group → the Third Galactic Arm → the Milky Way → the Local Supercluster → the supercluster → the universe → beyond the universe. I want to read a book with this kind of scale. I wonder if one exists? Preferably a traditional-style novel.

Exploring Nature, the Supernatural, Mythology, the Universe, and Celestial Bodies Through Science

Please Recommend Science Fiction on the Level of The Three-Body Problem

Hmm... something like Right Eye, for example.

Any Sci-Fi Stories?

Looking for books like "Hello, AD 2250".
