@Chimi_Chuang_Tzu @Scubbie FYI we already know how to travel to the future and it is no secret, it has been proven and tested over and over again, problem, you have to go really fast, close to the speed of light to get any significant time travel to the fiture, look it up if you dont believe me. But as far as I know we dont know, we dont even have a theory of hoe to travel back in time.
