No gullible travel...it just means a particle can go faster than the speed of light, which i kind of doubt, but im no scientist. But even if its true it has nothing to do with traveling backwards in time. Time goes one way in the physical world. You may be able to slow it down or speed it up FROM YOUR PERSPECTIVE. But backwards is not an option

Its not about the fact that we dont have the technology yet. There are laws set in place for the physical realm that dont permit this. Its about understanding the concepts of the physical world. Anything can be done in the mind, however.
