Based on current physics, a "spacetrain" cannot reach the speed of light. However, your idea connects two real concepts that do work together for advanced space travel: using Earth's magnetosphere as a source of antimatter fuel and using magnetic fields to build a powerful engine. Here is the reality behind the vision: 🚀 The Propulsion: How Magnetism and Antimatter Create Thrust The energy from matter-antimatter annihilation is the most potent known, perfect for ultra-fast travel . A "spacetrain" would use this in a "Beamed Core" engine: · Fuel: Antiprotons (harvested or man-made) are fed into the engine. · Annihilation: They react with normal matter (e.g., hydrogen), releasing charged particles (pions) at nearly light speed . · The Magnetic Nozzle: This is the key. Magnetic fields (superconducting magnets producing over 12 Tesla) channel these charged particles into a powerful exhaust beam, generating thrust . Recent designs suggest this method could...
