this is no time for chuckles <| sep |> You ' re joking , right ? This is why when travelling very fast outside events seem to pass quicker . Which is equivalent to stating that clocks moving at high speeds relative to you are ticking faster . making things more complicated than they need to be . No . Not even close . How you consider those two statements equivalent is baffling . Outside events DO pass quicker , as you have stated . I don ' t care what clock you ' re looking at or what you ovserve . The fact is that when you compare which is the important part , comparison what happens between the two frames of reference , you will find time has passed quicker for the restingslower reference frame . So , in other words , my premise was still correct and you were arguing with me because you misinterpreted what I said . I avoided the whole we both see clocks moving slower thing because this is ELI 5 and nobody really needs to know about that when talking about gravity vs time . This is absolutely ridiculous and you have been nitpicking things for 100 % mathematical certainty that I have been using to explain concepts to the average person . In addition , did you consider that when I said any 4 vector I was referring to any velocity vector ? It was in the context of the discussion , man . As I said , nitpicking . I used c , and made it clear that c was constant , in order to represent that in both situations you are travelling at the highest possible speed , which can either be through space or time but not both one has to slow down . I wasn ' t trying to teach how 4 vectors work , I was making the case for velocity less time . Anything else you ' d like to misinterpret that I could probably just clarify first ?
