Question

Describe the different hypothesis explaining the origin of the solar system.

Answer 1

Answer:

The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.

Explanation:

Answer 2

The earliest hypotheses included the Gaseous hypothesis of Kant, the Nebular Hypothesis of Laplace, the Planetesimal hypothesis of Chamberlin, the Tidal Theory/Gravitational Theory of Jean and Jeffery, the Binary Star Hypothesis of Russell, the Supernova Hypothesis of Hoyle, and the Interstellar Hypothesis of Schmidt.

Origin of the solar system:

• About 4.5 billion years ago, a thick cloud of interstellar gas and dust gave rise to our solar system.
• The supernova shockwave from a nearby exploding star, or supernova, may have caused the cloud to collapse.
• This dust cloud burst into a spinning disk of material known as a solar nebula when it disintegrated.
• The best-supported explanation of the birth of our universe revolves around an event known as the big bang.
• This notion arose from the discovery that other galaxies are rapidly moving away from our own in all directions as if driven by an old explosive force.
• The solar nebula theory is the only theory to date that fits all of the parameters outlined above.
• This implies that the solar system formed after collapsing from a molecular gas cloud 4.568 billion years ago.
