What's the most and least scientifically accurate concept in Three-Body?

I want to hear everyone's thoughts.

Most scientific:

- Sophon's 2D unfolding (protons have 11 dimensions, theoretical physics allows dimensional unfolding)

- Curvature propulsion (Alcubierre drive is legitimate theoretical physics)

- The Three-Body Problem itself (one of the three great problems in classical mechanics)

Least scientific:

- Trisolaran dehydration abilities (carbon-based life can't do this)

- Thought stencil (memories/beliefs can't be precisely written to specific neural circuits)

- Weaponizing physics (turning universal constants into weapons is too far-fetched)
