The problems of, getting crushed by too much matter seemed to be solved. Sending electric signals four times faster than light, gives me some ideas. What if, the signals travelled back in time, due the theory, that anything who travels faster than light will reverse time. But those signals has never been detected in the past. What if, there's a physical law to forbid us to see the signals - or the time travellers. Maybe time travellers are visiting us, but they can't influence the enviroment. Or maybe the signals or the time travellers just got into a parralel univers, created by themselve. And the matter, is no longer a puzzle, because the signals were moving four times faster than light, in the moment they where created - wasn't they?
