Hello folks... I am writing an article where I discuss discoveries in astronomy that were intially disregarded in rude or violent fashion. I have so far written about: Chandrasekhar and black holes Aristarchus and heliocentrism Galileo and heliocentrism Glen Penfield and the Chicxulub crater I am stuck for another one and would appreciate just a mention of a topic that I can explore. Preferably in an area of astronomy not covered. Your help would be eternally appreciated.
