Earth is Jupiter that Failed

Rocky planets, including Earth, is actually the gas giant planets like Jupiter that fail to form. It is based on the latest theories of planet formation revealed by Sergei Nayakshin, an astronomer at the University of Leicester, as reported by

The theory of planet formation is generally believed today is the core accretion. At first, there is a giant disc of gas around newly born stars.

Dust particles on the disk that coalesce to form larger objects called planetesimals which then form larger structures.
As a result of that process, the mass that formed was greater. At a certain mass, called critical mass, gravity will pull the mass of gas contained in the disk around the lump.
Thus, then rocky planets formed from a long and complicated process it.
Nayakshin proposed a new theory called tidal downsizing. Based on this theory, the blob of gas was originally formed in zones far from where the planet is generally found so far.
In the process, clumps of gas cools and shrinks to a still relatively massive planets, about 10 times the size of Jupiter.
During the shrinkage takes place, the dust particles contained in the disc of gas coalesce into larger and then "fell" into the center of the blobs of gas, solids forming a solid in there.
This is where the planet is finally formed a primitive rock with a blob of gas in the outer wrapper.
The next event, the disc of gas carrying this primitive planet near the star. Gas wrapping primitive planet is then "eaten" by the parent star.
Part of "survivors" are solid core only and some gas, spared because its density is relatively large.
Expropriation process gas is then formed wrapper Super Earth planet or rocky planet like Earth.
In other words, Super Earth and planetary rocks is essentially a gas planet that has no chance to grow up because the mechanism in the universe and the "crimes" of the star.
Nayakshin outlining a new theory of planet formation in the Monthly Notice of the Royal Astronomical Society journal which was published last August.
He acknowledged, as a new theory, there are still many shortcomings that must be covered and still be tested. He hopes the scientists deign further examine theories describing.
Responding to the theory Nayakhsin, Aaron Boley from the University of Florida who has conducted the gas giant planet formation process of tidal disruption that allow life to evolve on a more varied star system.
"This is another natural way to create planets," said Boley. The more planets, the greater the potential for life.
Nayakhsin himself said, the core accretion model and the tidal disruption have physical measures are the same but different proportions.
"In this case, the final model may be combined," he said. He also menbambahkan that rocky planets are formed in the process of tidal disruption may be measuring a "zero to 10 Earth masses."

The super earth is as real as Godzilla.
