I just want to add that apart from time dilation, velocity also causes length contraction wherein an object will be measured as shorter when it's moving relative to the observer versus from its own rest frame. I've always found it (and time dilation) to be very unintuitive to reason about with my monkey brain - relativity in general is just super weird.
