La gravedad en nuestro universo

The video explains gravity as a fundamental force that attracts objects. Earth's gravity keeps the moon in orbit, while the sun's gravity holds the planets in the solar system. The Milky Way galaxy, with its 200,000 million stars, is held together by gravity. This force also maintains the structure of the universe, making it one of the most crucial forces in existence.
