Okay this book had a lot of physics that went way over my head, but the overall premise--and philosophical output--was absolutely wild. I had to look up the three-body problem (mostly because while the book did explain it a bit, I like being to conceptualize in text form) because it was a fascinating concept, and my inner math kid leapt at the chance to read about it. The book itself had a lot of buildup to get through, so it was a slow process to get to the interesting parts. I can't say I remember most of the characters mentioned in the book (Ye, Wang, and Da Shi were the ones that clearly stood out), as I felt most of them represented just a general faction of beliefs about humanity and alien life. And boy, this book definitely touched on A LOT of philosophical and scientific outlooks regarding humanity in a historical and futuristic context. Also, I feel like a lot of this buildup hints towards a long game, and oh man, it's gonna get even wilder moving forward.
