Physicists: Tachyons can be reconciled with the special theory of relativity

Physicists from the University of Warsaw and the University of Oxford have proposed a new perspective on tachyons, hypothetical particles that travel faster than light. Previously seen as incompatible with the special theory of relativity, a recent study published in Physical Review D suggests that tachyons can actually enhance our understanding of causal structures within the theory. The research team identified that incorporating future final states, in addition to past initial states, resolves previous inconsistencies and makes tachyon theory mathematically coherent. This approach introduces a new form of quantum entanglement that intertwines past and future events. The study also speculates that tachyons may play a crucial role in the formation of matter, challenging existing notions about these superluminal particles. The findings open up possibilities for further exploration into the nature of tachyons and their potential implications in physics.
