Death's End

I don't know anything about physics beyond basic survival body knowledge, so this series was really fun to think about. There are so many concepts that were like a brain massage to learn and think about and try to incorporate into my understanding of the universe (which is part reality and part what I want to be involved). I liked the third book the best because it was the least laggy and the least sexist. This series felt like getting sucked into a story about aliens, then being dunk tanked into a mind blowing ground shifting epiphany about the physics of the world, then more compelling story, then someone else hits the dunk tank target, and on. This book had some really fun fantasy parts and it was cool to see this clearly extremely imaginative sci-fi writer stretch his equally brilliant fantasy/fairy tale muscles. I'd recommend the series if you're up for a time commitment and some minor perceptive reality crises.
