The new timeline for giant planet migration, ” may rewrite the history of the solar system

This is a visualization showing a large asteroid hitting the Earth. A new study suggests that a new timeline for the Earth’s early history.

The largest of the planets in our solar system would have drifted away from the sun is much, much faster than scientists previously thought, a new study suggests. Understanding this phenomenon can help researchers to discover the origins of life on Earth.

More than 4.5 billion years ago the planets of our solar system may have formed. In those early days, violent clashes between the rocky parts of the objects, and the planets, including our own, have created chaos in the still-developing storm that was in our cosmic environment.

Through the study of meteorites, and with the help of computer modeling, a research team, led by geologist Stephen Mojzsis, University of Colorado at Boulder is to offer a new timeline of the events that took place during the Earth’s early days.

These researchers estimate that, as a phenomenon known as the “giant planet migration occurred much earlier than previously thought. This “migration” is part of the solar system and evolution of the largest planets began to move away from the sun.

It’s a concept that Jupiter’s gravitational force affects the orbits of the outer planets, Saturn, Uranus, Neptune and pluto. And, by the mutual gravitational effect of the four giant planets of each migrate, and this migration leads to a small inward movement of the Jupiter is to the sun, and from the systematic to the outside, orbital position, Saturn, Uranus, Neptune and pluto,” Mojzsis said Space.com. This event has an influence on the orbits of all objects in both the inner and outer solar system.

“We believe that [the giant planet’s migration] has to be done in order to provide an explanation of the structure of the solar system,” Mojzsis said, adding that in this event, submit the jobs, positions, and populations of the various objects in our solar system.

At the moment, the reasons why the giant planet’s migration took place is unclear, but the research team has solved one mystery of this phenomenon, where it took place. The team suggests that the migration took place over 4.48 million years ago, much earlier than previously thought.

According to Mojzsis, the conclusions also support the idea that the Earth might be able to be calm enough to make it in life as early as 4.4 billion years ago. This is a lot earlier than 3.5 billion years old, that had previously been presumed to be the period of time when life on Earth was created, because that is the age of our oldest fossils.

“We believe that there is nothing to stop the origin of the biosphere and of its continued survival for at least 4.4 billion years ago,” Mojzsis said.

“The only way to do it is to sterilize the Earth to melting of the crust at a time,” Mojzsis added in a statement. “We have shown that this has not been done, since giant planet migration has begun.”

Huge impact of the methods

In order to come to these conclusions, Mojzsis and his team to discuss the details of the actual asteroids, since asteroid dating back to prior to planet formation. In addition to finding it for the first time in the “giant planet migration,” the team also found a lot of interesting information about the Apollo moon rocks. Previously, scientists suspect that there is a lunar impact that took place 3.9 billion years ago, and because of that, it was the age of the rocks seemed to be. In the study of the meteorite data, and the team could not find a single example of the space rock, which is behind the idea of a catastrophic impact event, less than the 4.5-billion-year-old.

Mojzsis explained that, while the rocks turned out to only be 3.9 billion years old, but radioactive ages were the most likely to be “zero.” This is likely to be caused by the melting caused by the heavy bombing of wwii which must have taken place at about the same time as the migration, Mojzsis said.

“The best way to find out is to put it the time … is that giant planet migration occurred in that period of time, resulting in a sweep or a bombing attack on the solar system, asteroids and comets, and debris of planet formation,” he added.

Apart from the analysis of the meteor data, the team used computer simulations to show that these giant planets have, in fact, begin to move in the direction of their present-day locations in the solar system is about 4.48 billion in the year-ago period.

This new research was published Aug. 12. in The Astrophysical Journal.
