Origin of the Earth-
The concept of planetary origin was first presented by Kant. This theory is popularly known as gaseous theory.
Laplace rendered nebular hypothesis in relation to the origin of the Earth. According to this principle, the origin of the earth is formed from a ring in many rings, which have separated from this nebula as a result of the difference in the speed of the movement from the circulation of a nebula with the cooling and shrinking of the nebula.
A theory related to the origin of the Earth was proposed by Jeans and Jeffries, according to them two stars in space were present. This theory is known as tidal hypothesis.
In terms of the origin of the Earth, the most detailed theory of the Big Bang theory is considered. George Lemaitier and Robert Begoneer of this theory were interpreted to explain the origin of the universe, the galaxy and the solar system. According to this opinion, there was a huge nebula built with heavy substances about 15 billion years ago, with the sudden explosion, the substance became fragmented all around. The re-creation of the particles of this scattered matter generated many objects, causing the galaxy to be born. The continuous expansion in the universe increased the distance between the galaxies. Later galaxies also exploded, from which the objects obtained were stars and re-explosions in the stars resulted in the formation of the Solar System and the planets.
