"Discovery: Solid Metal Ball Discovered in Earth's Core"

Researchers have discovered a solid metal ball in the heart of Earth's innermost core, estimated to be roughly the size of Pluto and at least 400 miles thick. This finding challenges the conventional understanding of Earth's layers and suggests the existence of a fifth layer. Seismologists studied shockwaves from earthquakes to make this discovery and believe that the metal ball may have been formed as a result of a major global tectonic event in the past.
