📜 Lore: Math and Science Errors in Three-Body — Fan Correction Compilation

📜 Science Errors in Three-Body

Liu Cixin's sci-fi is "hard sci-fi" — but not flawless. Here are some scientific "bugs" found by fans.

1. Light Speed Limit

Premise: Trisolaran fleet travels at 1/10 light speed.

Issue: At that speed, any cosmic dust would generate enough impact energy to destroy ships.

2. Sophon Communication

Premise: Sophons use quantum entanglement for instant communication.

Issue: Quantum entanglement cannot transmit information. It's a fundamental quantum mechanics limitation.

3. Dual Vector Foil Speed

Premise: The Foil spreads at light speed.

Issue: If it spreads at light speed, humans couldn't see it coming — it would arrive simultaneously with its light.

4. Stable and Chaotic Eras

Premise: The Trisolaran world has regular "stable era" and "chaotic era" alternation.

Issue: In a real three-body system, planetary orbits are completely chaotic — no "regularity" is possible.

5. Dehydration Energy

Premise: Trisolarans dehydrate and rehydrate.

Issue: Where does the energy go during dehydration? How is it regained during rehydration?

Why These Don't Matter

Liu Cixin said: "Sci-fi isn't a scientific paper. Sci-fi uses scientific elements to build a stage for human drama."

These "bugs" don't affect Three-Body's value as a novel. In fact, finding them is part of the fun of being a Three-Body fan.
