The Force of Gravity and the Birth of the Solar System

The video explains gravity as a universal force of attraction affecting all matter, giving weight to objects and shaping celestial bodies. It describes the formation of the solar system from a dense interstellar cloud, leading to the birth of the sun through nuclear fusion. The process of accretion in the protoplanetary disk formed planets and other celestial objects, with gravity playing a key role in their development and orbits.

Discuss the significance of the sun's nuclear fusion reactions.
