Our planet is truly unique.Many still seems incredible that set of circumstances that led to the emergence of life on it.People discovered a great many planets, but why one of them is not what is on earth?What is it so unique?
over the question of how the Earth came, people thought for many centuries.Of course, like him, no one can answer, but there are a number of very compelling hypotheses based on various scientific facts.
How did Earth
Earth - our home.It is an occasion to learn about it all you can.This beautiful planet that keeps a lot of secrets.How did the Earth?When some of these issues and myths were born.People imagine this process in different ways: some believe that it was created by God, others believed that it appeared by itself, that is, before the birth of God.
Note that the first scientific hypotheses, with which attempts to answer the question of how did the Earth, appeared only in the seventeenth century.One of them suggested a physicist from France.His name was Georges Buffon.According to his version of our world is the result of a universal scale disaster.The very accident occurred because the sun hit some big object.The collision caused the spread of "spray", which after cooling down and become planets.
Immanuel Kant also speculate about the origin of the Earth.His version was based on the possibility of the formation of the heavenly bodies.According to him, the entire solar system was initially cold dust cloud whose particles are in continuous chaotic motion.Not only do they repel each other, but still stuck together like a snowball.
Pierre Laplace also put forward an interesting hypothesis.He said that the planets and the sun emerged from the clouds of hot gas that reside in the rotation.This cloud is slowly but surely shrink.As a result, the compression rings were that eventually turned into the planet.Central Sun became a clot.
little later the world learned the theory of James Jeans.English scientist tried to explain not only education, but also the development of our solar system.According to him, once upon a time very close to the Sun flew some kind of star.Because of the increased gravity of the Sun and the star was the allocation of substances - from and originated the planet.
Otto Schmidt was our compatriot.Reasoning and research led him to believe that once the Sun was a big cloud.It consisted mostly of gas and dust.Over time, it began to form clots, which is becoming harder and harder, and centuries later began to move around its axis.As you know, these clots, in the end, and became known planets.
All these hypotheses have a lot in common.The naked eye can see that scientists thought in the same direction.Modern ideas about how the Solar System came and Earth, are built around the same thoughts.
What scientists say today?There is reason to believe that the planets and the sun emerged from the gas and dust that is interstellar matter.The largest cluster has evolved in the sun.The sun was a source of energy, affect the remaining clumps subsequently turned into planets.
should be noted that the shape and dimensions of the Earth are not the same as before.This proves the fact that the development is still going on.The speed of rotation of the Earth around the sun is also changing.Of course, all these changes can not just notice - they happen once in a thousand or even a million years.
Yes, there is no unequivocal opinion about the origin of the sun and planets.Even today it remains a mystery.
