Question
Explain Nebular Theory.
✓
Answer
- The concept was introduced in $1755$ by the German philosopher Emanuel Kant.
- According to him, billions of years ago, space had cold and motionless gaseous clouds.
- The reciprocal gravity of the gaseous gases caused friction, and the gaseous cloud heated up and transformed into a nebula rotating on its imaginary axis.
- Kant's ideology was refined by the French mathematician Laplace in $1796.$ He introduced the idea of a very hot nebula from the beginning.
- Heat was constantly emitted from the surface of this nebula.
- As a result, its heat gradually decreased.
- It slowly cooled down so its surface parts began to shrink and thicken.
- The centrifugal force began to grow rather than its centrifugal force.
- Due to the centrifugal force, a series of gaseous particles were released from the surface of the nebula from time to time and thrown into space.
- This mass of aerobic matter began to revolve around the nebula itself. Due to the gradual combination and aggregation of these gaseous substances, the annular gaseous substances were transformed into solid spheres.
- Which are known as planets.
- This whole process was repeated before some of the planets condensed to form satellites from some of the planets.
