Xeelee Sequence is a series of hard science fiction novels and short stories written by British author Stephen Baxter, and spans billions of years of fictional history (leaving 40k in the dust with its "mere" 10,000), with plots revolving around theoretical physics, futurology, multiple universes, artificial intelligence, faster-than-light travel, and the usual existential and social philosophical issues that tend to go with such works.
Most relevent to /tg/'s interests, though, is that Xeelee is grimdark. Like, holy shitballs, final word on the matter, makes 40k look like butterflies and rainbows in comparison, grimdark. The Interim Coalition of Governance, just to pick one example, is arguably the most grimdark galactic government in all of fiction. A place where the concept of hope and humanity has been forgotten so hard that trillions of child soldiers are sent to fight (and get slaughtered) in a war they don't have a hope in hell of winning, and the Coalition knows it and doesn't care.
