China's nuclear fusion reactor, dubbed the "artificial sun," has breached a major fusion limit by firing plasma beyond its usual operational range, advancing humanity's slow progress towards near-limitless clean energy.
The Experimental Advanced Superconducting Tokamak (EAST) kept plasma — the high-energy fourth state of matter — stable at extreme densities, which was previously seen as a major obstacle in the development of nuclear fusion, according to a statement released by the Chinese Academy of Sciences.
