Formation of Planets
(Nebular Hypothesis, cigar-shaped Theory, Binary Theory)
In the realm of early scientific theories about the formation of planets, the Nebular Hypothesis emerged as one of the prominent and influential arguments. It was first proposed by the German philosopher Immanuel Kant and later revised by the mathematician Pierre-Simon Laplace in 1796. This hypothesis put forth the idea that planets originated from a cloud of material surrounding a young, slowly rotating sun.
Another significant development in planetary formation theories occurred in 1900 when Chamberlin and Moulton introduced the concept of a wandering star approaching the sun. As this star passed by, it caused a separation of material from the solar surface, resulting in the formation of a cigar-shaped extension. As the passing star moved away, the detached material continued to revolve around the sun, gradually undergoing condensation and eventually coalescing to form planets. This theory garnered support from scientists such as Sir James Jeans and later Sir Harold Jeffreys.
Subsequently, further considerations emerged regarding the existence of a companion to the sun, known as the Binary theory. According to this line of thought, a companion star coexisted with the sun, influencing the formation of planets. This hypothesis added another layer of complexity to the understanding of planetary origins.
In 1950, Otto Schmidt in Russia and Carl Weizsäcker in Germany made notable revisions to the Nebular Hypothesis. While differing in certain details, their revised version proposed that the sun was surrounded by a solar nebula composed mainly of hydrogen, helium, and dust particles. The friction and collisions among these particles within the nebula led to the formation of a disk-shaped cloud. Over time, this cloud gradually underwent a process of accretion, whereby smaller particles clumped together to form larger bodies, eventually resulting in the birth of planets.
The Nebular Hypothesis and its subsequent revisions have contributed significantly to our understanding of planetary formation. While early theories provided initial frameworks, the ongoing advancement of scientific knowledge continues to refine and expand our comprehension of the intricate processes that shape the origins of celestial bodies like planets.
