Question

Explain the tidal hypothesis.

Answer 1

Hint :Sir James Jeans, a British scientist, proposed his "tidal hypothesis" to explain the origin of the earth in 1919. One of the modern theories for the origins of the earth and solar system is the tidal hypothesis. Jeans proposed his hypothesis based on a set of axioms. While Newton explained tides by describing the tide-producing forces, Bernoulli described the static reaction of the Earth's waters to the tidal potential.

Complete Step By Step Answer:
The following are the tidal hypotheses:
The sun was once a massive incandescent gaseous mass of matter.
Aside from the Sun, there is another star in the universe known as an "intruding star." This star was significantly larger than the primitive sun.
The sun was also stationary on its axis, whereas the intruding star was moving along a path that was predestined to bring it closer to the primitive sun.
On the surface of the "primitive sun," the tidal force "affected the intruding star."
According to James Jeans, a large amount of matter was ejected from the primitive sun as a result of the intruding star's massive gravitational force, which later became the building material for future planets.

Note :
In 1929, Harold Jeffreys, a British scientist, modified James Jeans' original tidal hypothesis and presented his concept as the "collision hypothesis." Before the birth of our solar system, there were three stars in the universe, according to Jeffreys. The first was our primitive sun, the second was its 'companion star,' and the third was an 'intruding star,' which was approaching the 'companion star.'
