Question
Discuss tidalism explaining the origin of the earth.
✓
Answer
The theory of tides for the origin of the solar family was introduced in $1919$ by English geographers James Jeans and Jefferies.
According to this theory, a traveling star passed close to our Adisurya with a giant atmosphere.
It was many times larger than the sun.
The tide rises on the surface of the sun due to its gravitational force.
As the traveling star got closer and closer to the sun, the tide rose.
The aerial mass in the shape of a cigar and a cigar attracted the tourist star and released it from the sun.
As the traveling star moved away, the force of gravity diminished. The part separated from the sun gained rotation and orbital motion due to the gravity of the sun.
Over time, the shape of the cigar began to change.
