Hello. I need some help understanding time dilation. So the idea is that moving clocks tick slowly. Say there was an observer A who, by his frame of reference, is stationary, and he sees an object B moving past it at high velocity. From what I understand, to A it would appear as if B's clocks are ticking slowly compared to his. In other words, to B it would appear as if A's clocks are ticking faster. But that's from the point of view of A. If you look at it from the point of view of B, it is he who is stationary, and A is the one who is moving at high velocity. So A's clock should be ticking slower compared to B's. There's seemingly a conflict between these two conclusions. Where's the mistake in my understanding?
