@chrisvest@mastodon.social is it? I thought the current scientific consensus was about 4.5 billion years.

@hugo@social.treehouse.systems 4.5 bn is the age of the earth itself, I think. The debate on the solid inner core is between two different methods of measuring. Upper bound is 4.2 bn by thermal model. Paleomagnetic points to 0.5 bn: https://en.m.wikipedia.org/wiki/Earth's_inner_core#Paleomagnetic_evidence
