Fate of Worlds

Fate of Worlds mixes complex scientific concepts with imaginative world-building. I wonder how Larry Niven decided where to draw the line between plausibility and fantasy.

With so many worlds and characters involved, I found myself struggling to keep track of everything. Is that just me, or was the scope intentionally vast and intense?

The universe feels so richly developed—was it based on any particular scientific theories or purely imagined from scratch? I’d love to hear about the creative process behind it.
