Scientists at SLAC National Accelerator Laboratory have successfully recreated the extreme pressure conditions of Earth’s outer core in a laboratory, providing new insights into how iron behaves under such intense conditions. This study reveals how iron, under stress, uses a mechanism called "twinning" to strengthen itself before it starts to flow. The findings could help explain the behavior of iron in planetary cores and offer clues about massive iron asteroids in our solar system. This breakthrough brings us closer to understanding the Earth's inner workings and the forces shaping our planet.
