Gravity is a fundamental force that affects everything in the universe, from the smallest particles to the largest galaxies. It governs the movement of planets, stars, and galaxies, as well as the orbits of moons and satellites. On Earth, gravity gives us weight and keeps our atmosphere intact, but in space, it creates fascinating phenomena like black holes and gravitational lensing.
In fact, gravity is so powerful that it can bend light, allowing us to observe distant galaxies that would otherwise be hidden behind other objects. It is one of the most mysterious forces in nature, and understanding its effects is key to unlocking many of the universe's secrets.
