Just a physics buff so bear with me, this has been bothering but I am sure there is a simple answer. I watch a lot of physics and science programs on TV. When discussing red shift the explanation is that the light from objects that a further away is more red-shifted than light from closer objects. The conclusion is that the Universe is accelerating… But, my question is, isn’t this telling us that older light is more red shifted than younger? And that the Universe is slowing down..? Or is it that over time the amount of red shift increases? I.e. light from a particular star is more red-shifted today than it was 20 years ago?
