To be honest , I don ' t think I believe that . Firstly , no object massless or not can ever exceed the speed of light . So it doesn ' t even make sense to theorize about what happens if something does . And secondly , at the speed of light , you ' re not actually jumping to the future . Time just stands still for you so you don ' t age or feel time pass . So there ' s no reason to think there ' s any speed related method of clean time travel . Going it back in time would require actual travel in the fourth dimensional direction . We would need something akin to a wormhole to do that , and speed isn ' t involved there . I ' m not convinced Einstein said anything of the sort . <| sep |> That ' s what made me like it even more , loved that flow from lowlife
