>The Nile's unchanging path, however, has been a geologic mystery because long-lived rivers usually move over time. Researchers at The University of Texas at Austin have cracked the case by linking the river's flow to the movement of rock in the Earth's deep mantle. In the course of their investigation, they found the eternal river to be much older than anyone realized, with the scientists estimating the age of the Nile to be 30 million years—about six times as long as previously thought.
