What did gravity create when 99% of the gas and dust materials were gathered into the center of a flattened disc during the formation of the solar system?

Answer 1

During the formation of the solar system, as gravity caused about 99% of the gas and dust to gather into the center of a flattened disc, the primary result was the creation of the Sun. This process is part of the nebular hypothesis, which describes how the solar system formed from the gravitational collapse of a giant molecular cloud. The material that remained in the surrounding disc eventually coalesced to form the planets, moons, asteroids, and other bodies in the solar system. In summary, the central accumulation of material led to the formation of the Sun, while the residual disc material gave rise to the planets and other smaller celestial bodies.
