@tux3 human brains are constipated. Our current interpretation of data like that from Hubble is that space is expanding. But it could equally be that matter is contracting. Space is the absence of matter. You cannot increase space anymore than you can add ‘cold’to a glass of water. By assuming that light is invariant, we would observe decreasing light frequencies as we measure older light.because We and our rulers have ‘shrunk’. This interpretation also eliminates the need for inventing dark matter and dark energy to explain our observations
