Three billion years ago, a rock from space struck what is now Western Australia, leaving a wound in the earth that time nearly erased. Scientists have now read that wound with enough precision to settle a long-standing debate, confirming the site as the oldest known asteroid impact crater on Earth. The finding is more than a record broken — it is a fixed point in deep time from which humanity can begin to trace the violent, formative forces that shaped the world we inhabit.
