OREANDA-NEWS A team led by University of Colorado Boulder geologist Stephen Mojzsis has developed a new timeline for the brutal period in the history of our planet. In a study published on August 12, scientists focused on a phenomenon called the migration of giant planets. This is the name of the stage in the evolution of the solar system in which the largest planets, for reasons still unclear, began to move away from the sun. 

Based on records from asteroids and other sources, the group estimated that this event, which changed the solar system, occurred 4.48 billion years ago, much earlier than some scientists thought. To explain these times the researchers suggested that our Moon and Earth were hit by a wave of comets and asteroids at about the same time. But not everyone agreed with this theory. The surfaces of the planets were altered by impacts and local events about 4 billion years ago. The same does not apply to asteroids. Their record goes much further. 

The solar system must have been heavily bombed. Mojzsis explained that this massacre was probably started by the giant planets of the solar system, which, according to researchers, formed much closer to each other than today. The results, Mojzsis added, open up a new window for exploring the emergence of life on Earth. Based on the team’s results, the Earth may have been calm enough to support living things 4.4 billion years ago.
