Greetings everyone, I asked my professor about this, recently. I had always heard that if you could gain the impossible amount of energy necessary to run beyond the speed of light, you would travel backwards in time. But he however, told me something that I have never heard before. He said, "If you were simply breaking the laws of nature to run that fast with just the speed produced by that energy, time would no longer exist; because going faster than light, in that way, is the same as accomplishing a nonsense task like drawing a squarclelangle. At those speeds, there is no such thing as time, you would be a being beyond time." He did note that FTL was not necessarily impossible, but doing it in that way wasn't even a thing that made sense. It was like asking a question in a made up language. He is an incredible-awesome professor, but is he right about this? Your answers would be greatly cherished.
