The missing 500 million: Cosmic bombardment melted Earth's first crust
New research suggests a prolonged barrage of asteroid impacts melted Earth's early crust and may have sparked the origin of life.
📍 Where it landed
An extended barrage of asteroid impacts melted Earth's first crust and made the planet too hot to form continents. This cosmic bombardment was identified by physicists as an unexpected reason for the origin of life.

Where it stands
Recent studies indicate that an extended period of cosmic bombardment kept Earth too hot to form continents, effectively melting the planet's first crust. This period of intense asteroid activity is linked to a gap of 500 million years in the geological record.
Coverage from Ars Technica, Universe Today, and ScienceDaily emphasizes the role of these impacts in preventing early continental formation. Meanwhile, reports from Baku.ws and Inshorts highlight that these same asteroid events may have provided the spark for life on Earth.
Future attention will focus on the relationship between these cosmic impacts and the origin of life, as well as the implications of the missing 500 million years of crustal history.
