Question

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

Answer 1

When 99% of the gas and dust materials were gathered into the center of a flattened disc during the formation of the solar system, gravity created the protoplanetary disk. This disk, also known as the accretion disk, consisted of rotating material surrounding the young Sun in the center. Within this disk, particles and materials gradually began to collide and stick together, forming larger and larger objects called planetesimals. Over time, these planetesimals further collided and merged, eventually leading to the formation of planets, moons, asteroids, and other celestial bodies within the solar system.
