Nebula hypothesis in the year 1796

Answer 2

Nebular Theory was the hypothesis regarding the origin of the Earth that was presented by the French mathematician Laplace.

• The Nebular hypothesis of Laplace is one among many of the earliest theories on the origin of Earth.
• Nebula is a Latin word meaning 'cloud' or 'mist'.
• According to Laplace's hypothesis, there existed a hot, gaseous, and massive nebula in space.
• This massive and hot nebula has been spinning on its axis since the beginning.
• But radiation resulted in the heat loss from the surface of the nebula due to which it kept cooling down.
• This contraction cooling led to the shrinking of the nebula.
• But this concept of the nebular hypothesis was disproved at the beginning of the twentieth century due to the advancements in observational technologies like telescopes, etc.
