Gravity train

A gravity train is a theoretical transportation system that uses gravitational forces to move objects—typically designed for long-distance travel with minimal energy consumption. The concept fundamentally revolves around utilizing the natural pull of gravity to facilitate movement along a track, which could be positioned in a tunnel extending through the Earth or a similar efficient path. Here's how it could work: 1. **Concept and Design**: A gravity train might involve a deep tunnel drilled through the Earth from one point to another.
