So there is a problem I don't get. I special relativity, things moving relative to me, I see them as experiencing more time/ slower time. Ok....so then I should also see it's velocity decrease. If I see it's clock running slower, so should I it's velocity. V=....m/s So if I see it's time slow down then V=.....m/2s. And if the answer is, distance also decreases, if I saw something run past me at 0.5c, I should see the path before it shrink? Distance decreases only from the point of view of that thing (lenght contraction), but not from mine. Thank you for help, I really don't get this.
