I guess you are referring to the recent news from the particle accelerator at CERN, where some scientists thought they had measured a neutrino (a very small, almost massless particle) moving faster than light. They have now realised that this was a mistake (caused in part by a loose wire!). So we still think that nothing can go faster than light.
If something could go faster than light, we would need to rethink a lot of physics. I’m not sure if this would make time travel possible, maybe Jarvist can provide more info?
