Today, Chris and Jesse get into a discussion about Earth’s oldest material. Earth is 4.568 Billion years old. First of all, that’s amazing the geochronologists have refined this down to 3 decimal places. How do we know this? The oldest grains ever found are 4.38 billion years old. If that’s the case, then how do we know the Earth is significantly o…
