- detrites 4y agoAlright, 26673 LY within 0.3% accuracy: https://www.aanda.org/articles/aa/abs/2019/05/aa35656-19/aa35656-19.html https://www.aanda.org/articles/aa/abs/2019/05/aa35656-19/aa3... (So "24650BC" for... context.)
- awb 4y ago0.3% is +/- 80 years. So it’s not 24650BC, it’s 24570-24730BC. And the farther distance you go, the greater the uncertainty. And when measurements improve or are revised, everything would need to be recalculated. So, for posterity, it would be 24570-24730BC (2023 measurements). Or, 2023 is simpler.
