Gravity is the force that governs the motion of all celestial bodies, from the smallest particles to the largest galaxies. It holds planets in orbit around stars, governs the formation of stars and galaxies, and influences the structure of the universe. Without gravity, planets would not form, stars would not burn, and the universe as we know it would not exist.
In addition to its role in planetary and star formation, gravity also affects the passage of time, as described in Einstein’s theory of relativity. Massive objects like black holes create strong gravitational fields that warp space-time, allowing scientists to observe strange phenomena like gravitational lensing and time dilation.
