I'm just asking when I woke up in the morning I just remembered a YouTube video about time traveling,a thing or a machine that is faster the the light can cause up time-warping(or time-travel). So a brilliant Idea just come out on my mind to make a sketch plan for a machine that can run fast in a miles but it not possible as well.
A bullet train in Japan can run as fast as a sportscar but I need an idea for this (time-travel). In YouTube I just randomly found an interesting video that America has has a secret plan for making a time machine BUT I DON'T BELIEVE AS SOOO. So my point is what machine that can run fast
