My question embraces history, cosmology and astronomy, I hope this is an appropriate forum to ask it, if not I apologise and hope to be re-directed.
I have read, but lost the reference, that when the remnant of Magellan's expedition returned in September 1522, their log showed a date the day before that of the inhabitants of the port where they landed. This is important evidence that the Earth orbits the Sun, but it is not mentioned in any reference to the voyage that I can find. Please, does anyone have more details, and where I can find out more about it?
Edited to correct an error , it was a day lost, not gained
