solar Nebula theory in your own words easy word
Answers
Answer:
The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas. It is believed that the sun, planets, moons, and asteroids were formed around the same time around 4.5 billion years ago from a nebula
Answer:
Definition: Solar Nebula is a large disc-shaped cloud of gas and dust from which planets, the sun, and other bodies of a solar system are formed. The word “nebula” is a Latin word for “cloud.” The solar nebula was a twisting, flattened disk of gas and dust from which the solar system originated ~ 4.6 Ga ago, where Nebulae are made of residue and gases - hydrogen and helium. The residue and gases in a cloud are extremely fanned out, however, gravity can gradually pull together the bunches of residue and gas. The development and upgrading in the Solar System started about 4.57 billion years prior with the gravitational breakdown of a little piece of a giant molecular cloud. The greater part of the falling mass gathered in the middle, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, space rocks, and other little Solar System bodies framed. This model, known as the nebular hypothesis, was first evolved in the 18-century by Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace.
Theory: In 1755, the German philosopher Immanuel Kant suggested that a nebula in a gradual rotation is slowly pulled together by its own gravitational force and flattened into a swirling disk that gave birth to the Sun and planets. During the late 19th century the Kant-Laplace views were unsupported by the British physicist James Clerk Maxwell, who showed that, if all the matter contained in the familiar planets had once been diffused around the Sun in the form of a disk, the shearing forces of differential rotation/twisting would have obstructed the condensation of individual planets.
Failure: For quite a few years, most astronomers supported the presumed collision theory, wherein planets were considered to have formed because of a close approach to the Sun by another star. Protests have been raised to the theory of collisions, which are more persuasive than those to the Nebular hypothesis, particularly since it was changed during the 1940s.The masses of the original planets were thought to be greater than in the prior version of the theory, and the obvious distinction in momentum was ascribed to the magnetic forces associating the Sun and the planets .Hence, the nebular hypothesis consequently became the predominant theory of the inception of the solar system.
The nebular hypothesis is the most acknowledged model in the field of cosmogony to explain the formation and evolution of the Solar System. This theory suggests that our solar system is made up of gas and dust orbiting the Sun. According to the nebular theory, stars form in massive and dense clouds of molecular hydrogen - giant molecular clouds or GMC. These giant clouds are gravitationally precarious, and matter combines inside them to more modest denser clumps, which at that point rotate, collapse, and form stars. Star development is an intricate cycle, which consistently creates a vaporous protoplanetary circle around the youthful star. This cycle may prompt planet development, which is an uncovered actuality up until now
