we are likely very near the centre of the universe filled with billions of galaxies with billions of stars in each. This is what Edwin Hubble concluded; his observations of the galaxies redshifts indicated to him that we are at the centre of a symmetric matter distribution. But Hubble rejected his own conclusionthat we are in a very special placeon philosophical grounds.
2 And Hubble wasnt alone in realizing this situation:
People need to be aware that there is a range of models that could explain the observations, Ellis argues. For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations. Ellis has published a paper on this. You can only exclude it on philosophical grounds. In my view there is absolutely nothing wrong in that. What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that.
