Apparently these ages are not a problem because of the errors in the estimates: 14.46 ± 0.8 billion years vs 13.799 ± 0.021 billion years. Turns out we need most of that 0.8 billion years error shift in order to stay consistent. |
This a really good lesson in why we should only ever quote our measurements with error bars!
