A shattered asteroid may have bombarded Earth 800 million years ago

A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago. The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars. The bombardment may explain ancient lunar craters and could have contributed to major climate and biological changes on Earth.
