I have always been puzzled by how we see an object from the past and can tell what it is doing now if it is billions of light years away. Given that; 1. the shift in the measurement of the light spectrum indicates the speed at which an object is retreating or getting closer. 2. that the furthest objects are retreating quicker than the nearest. 3. that when we look far away we are looking into the past. Q1> How do we distinguish that an observable shift in the light spectrum is greater or less now than at any other time in a distant object's time line? Q2> If the universe expanded quicker in the early stages of its existence and then progressively slower, would we not be observing the light that is reaching us now from that period as red shifted more than from objects closer to us?
