Astrophysicist: “A vibrant scientific culture encourages many interpretations of evidence”

They determined the orbital periods of Venus, Mars and Mercury around the Sun, but Earth was at the centre of their Universe. I came […]

Darwinism validated not by evidence but “by simplistic games models borrowed from 1940s economics”
