A 20-year-old mystery of the North Sea's Silverpit Crater has been solved. Researchers confirmed an asteroid or comet struck the region 43-46 million years ago, forming the rare geological scar. Advanced seismic imaging and rock analysis revealed shocked minerals, the hallmark of hypervelocity impacts. This 160-meter-wide impactor triggered a colossal tsunami, reshaping the seabed and offering new insights into Earth's dynamic history.
