Tachyons: Faster-Than-Light Particles That Align with Einstein's Relativity
An international team of physicists has proposed that tachyons, hypothetical particles that travel faster than light, could be compatible with Einstein's special theory of relativity. Their research suggests that incorporating both the initial and final states of a system into calculations resolves previous theoretical challenges, potentially allowing tachyons to exist and offering new insights into quantum theory and the formation of matter.
