ワームホール物理学（Wormhole Physics）
時空のショートカット（近道）。
Wormhole physics explores the Einstein-Rosen Bridge, a topological feature of spacetime that functions as a tunnel between two distant regions. First derived from the General Relativity equations, these structures represent a solution where two Schwarzschild black holes are joined at their event horizons. In modern theoretical physics, the focus is on Traversable Wormholes (Morris-Thorne wormholes), which would allow matter and information to pass through without being crushed by gravitational singularities. This requires the presence of Exotic Matter to provide 'negative pressure' to keep the throat open.

紙の上にいるアリを想像してください。紙の端から端まで歩くと時間がかかりますが、紙を半分に折って穴を開ければ、アリは一瞬で反対側に行けます。その「穴」がワームホールです。

## The Throat Stability Problem
1. Exotic Matter: Must counteract the massive gravitational pull toward the center.
2. Tidal Forces: Why Schwarzschild wormholes are lethal vs. Morris-Thorne wormholes.
3. Causality: The risk of creating a time-loop (Grandfather Paradox).
