On the Tired Light Hypothesis

The first model of cosmology that I was exposed to, when I was just entering elementary school age, was the Static universe model, because that's all my father knew. According to this model, the universe is infinite in all directions, it is eternal, and it is not going anywhere. Of course I accepted it, because that is what kids do: accept everything presented to them as a fact.

Then, during elementary school, I heard of the Big Bang and the expansion of the universe; this new model of cosmology made me feel a bit uncomfortable, but again I accepted it, because a) that's what the scientists said, and b) I could go to my father and tell him that he was wrong.

Theory vs. Practice

 In theory there is no difference between theory and practice, but in practice there is.

-- Benjamin Brewster, ca. 1882 (according to Quote Investigator)
