What is Gravity?

The video explores gravity as a long-range attractive force affecting all objects with mass and energy. It discusses how gravity keeps celestial bodies in orbit and how every object in the universe is gravitationally attracted to each other. Isaac Newton's discoveries about the inverse square law and the proportionality of gravitational force to mass are highlighted. The video also explains that gravity affects not only massive objects but also light and energetic particles, leading to phenomena like light bending around the sun and being trapped by black holes.
