55 Origin of planets

Menu | back |
An attempt has been made to use computer simulations to explain how gas planets, rocky terrestrials and ice planets could have been formed. It is still an open question how a disc of dust (as allegedly surrounded our sun) could have accumulated to create planets. The known gravity is insufficient to accomplish this. Moreover, the orbits of the planets and moons in our solar system do not have a random structure, but they follow exact mathematical laws.
The process of a supernova explosion, in which a star such as the sun develops and heavy elements such as iron, nickel, and lead are formed, can be simulated. It is also possible to calculate how a gas and dust disc could have been formed. However, it is still unclear and highly controversial whether planets could have formed from such a gas and dust disc and how that could occur (1).
Gas planets:
Computer simulations of the formation of our solar system showed that gas planets do not form in a disc surrounding a star, because the gravity is far below the limit required for accumulation of the gas. Jupiters mass is approximately 1,000 times less than the sun. If it is not possible even for the sun to accumulate by gravity, it is even less imaginable that the mass of Jupiter would suffice to accumulate. According to theory, a number of supernova explosions would have been required to achieve it.
Rocky terrestrials:
To explain the formation of rocky terrestrials, it has been proposed that a number of meteorites could have been aggregated. However, meteorites do not consist of dust, but rather solid rock or iron. Moreover, the meteorites themselves have too little gravity to accumulate.
Ice planets: The development of ice planets is even more difficult to explain. They would have to manage with very little material so that accumulation would require an extremely long time.
Precious metals on Earth:
According to the common theory on formation of the Earths crust, there should be no precious metals on the surface of the Earth. Precious metals such as gold, platinum, and iridium join under certain conditions readily with iron. Therefore, they would have migrated slowly during the molten state into the iron-rich core during the hot primordial period which existed allegedly for a million years.
In order to support the conventional model of development of our planet, it has been proposed that all deposits of precious metals close to the surface originated from impacts of metallic meteorites (2). The conventional model of development of the planetary system is rarely questioned.
