Researchers have unearthed 3,600-year-old evidence that Tall el-Hammam was destroyed by a 'cosmic impact' and may have inspired Bible story of destruction of Sodom. They uncovered pottery shards that had their outer surfaces melted into glass, 'bubbled' mudbrick and partially melted building material. The event was 'larger than the 1908 Tunguska explosion, experts say. This impact leveled the city, leaving the palace and surrounding walls flat. Human remains (including a skull) were found, indicating exposure to temperatures above 200°C.
