A speculative framework proposing the existence of particles that naturally travel faster than light—tachyons, in physics jargon. Theory of FTL Particles suggests that just as there are particles slower than light (bradyons) and particles exactly at light speed (luxons), there may be particles that must always exceed light speed (tachyons). These particles would have imaginary mass and weird properties: they'd slow down as they gained energy, speed up as they lost it, and could never decelerate to light speed. No tachyons have ever been detected, but they remain a theoretical possibility—and a staple of speculative physics.
Theory of FTL Particles "Tachyons would always travel faster than light. Slow them down, and they gain energy; speed them up, and they lose it. FTL Particles theory says they might exist, might carry information, might even explain quantum weirdness. We've never seen one, but the math lets them be. Sometimes that's all a theorist needs."
