E PLANET EARTH

We have only one earth, so it is our duty to keep and leave this earth clean and peaceful. When will the earth be clean and peaceful? Let's talk more about it.

the origin of the earth

How did the earth happen? Since ancient times there have been many attempts, some of them even remarkably brilliant in giving satisfactory answers to the above questions. However, it was only in the eighteenth century that a valid hypothesis was found useful enough to be discussed by modern scholars. In 1755, the great German philosopher, Immanuel Kant, claimed that the solar system (sun, planet, moon, comet, etc.) was formed from a nebula (ie a thin gas mass like a vast mist).

At about the same time, the French naturalist George Louis Leclerc, Comte de Buffon, answered himself the question: "How was the earth born?" He believed that centuries ago the sun was clashing with a comet and as a result, a large amount of matter was forced out of the sun. This material is steering. it became cold and developed into a planet. planets.

Buffon's choice, that comets are the cause of collisions is not appropriate, because comets are so insignificant compared to the sun, so comets are unlikely to affect the sun.
