Question
Give two theories that explain the evolution of the solar system and the origin of the earth.
Answer
1. Passing star theory
The Passing Star Theory proposes that a massive star, possessing stronger gravitational force, came close to our Sun. As it passed by, this star's gravitational pull caused the Sun to release significant amounts of gaseous materials. These materials then underwent a process of splitting, cooling, and condensing, eventually leading to the formation of planets within our solar system. This theory suggests that the influence of the passing star played a crucial role in shaping our planetary system.
2. Nebular cloud theory
The Nebular Cloud Theory proposes that our solar system formed simultaneously with the Sun from a rotating cloud of dust and light elements, known as a nebula. This nebula eventually flattened into a protoplanetary disk, leading to the formation of a central star, the Sun, surrounded by planets that formed from the material orbiting it. This widely accepted hypothesis explains the origin of our solar system.
