Well, if this Higgs particle does exist, we could have limited time travel - travel from the point the machine was created to - theoretically - the end of time. If data is sent forwards and backwards through time, and we had machines which could replicate the human body (Nanobiotics, perhaps? There would be an issue in maintaining long-term cerebral stability, but still...) then a person in the future could 'time-travel' back to when the machine was first created. All of the data required to create the person (And replicate their brain patterns) would be sent backwards in time using the Higgs Singlet, and when it is received in the 'past' that person could be made on the spot. Technically it's time travel! Kinda.
