This story tells of Saitama while training, asking Professor Hilum, why he saw a bald person running in front of him while training, the Professor also explained that "it is possible that you have exceeded the speed of light, surely you are asking, right?, why humans or objectsartificially can't go beyond the speed of light?, because light covers space and time, if you can go beyond the speed of light then you are the same as going beyond space and time, it's possible that the person you see is yourself in the future because you ran too fast untilbeyond time itself and if you stop running you will return to your current Saitama"
