Tachyons: Faster-Than-Light Particles, Quantum Instabilities, and the Physics Beyond the Light Barrier
Abstract Few concepts in theoretical physics occupy as unusual a position as the tachyon. Originally proposed as a hypothetical particle that could move faster than light, the tachyon quickly became associated with some of the deepest questions in relativity: whether the speed of light is an absolute barrier, whether cause must precede effect for every […]
