  8. Large number of hypotheses were put forth by different philosophers and scientists regarding the Origin of the earth


  9. Earth originated from cold gaseous cloud, which eventually started spinning and became hot. With increase in speed, rings were separated from the central mass (sun) and planets were formed. Gaseous hypothesis Immanuel Kant The hypothesis considered that the planets were formed out of a cloud of material associated with a youthful sun, which was slowly rotating. Nebular hypothesis Laplace Otto Schmidt in Russia and Carl Weizascar in Germany


  10. Wandering star approached the sun. As a result, a cigar-shaped extension of material was separated from the solar surface. As the passing star moved away, the material separated from the solar surface continued to revolve around the sun and it slowly condensed into planets Chamberlain and Moulton Binary hypothesis We agree with Chamberlain and Moulton Sir James Jeans and Sir Harold Jeffrey

  12. Big Bang Theory Expanding universe hypothesis Origin of the Universe Edwin Hubble 1. In the beginning, all matter forming the universe existed in one place in the form of a iny ball" (singuler atom) with an unimaginably small volume, infinite temperature and infinite density. 2. At the Big Bang the "iny bal" exploded violently. This led to a huge expansion. It is now generally accepted that the event of big bang took place 13.7 billion years before the present. The expansion continues even to the present day. As it grew, some energy was converted into matter. There was particularly rapid expansion within fractions of a second after the bang. Thereafter, the expansion has slowed down. Within first three minutes from the Big Bang event, the first atom began to form. 3. Within 300,000 years from the Big Bang, temperature dropped to 4,500 K (Kelvin) and gave rise to atomic matter. The universe became transparent
