Quote from: Matt on September 10, 2019, 02:40:38 PMYou can't push past c, so there is no possibility of reversing time. To travel at the speed of c in an external reference frame, you travel at infinite speed in the moving frame. No matter how much faster you try to go beyond infinity, you are still travelling at the speed of infinity. To the external viewer this appear to be c. So it's impossible to go faster than this.
