What is GRAVITY? How does GRAVITY work?
Gravity is an invisible force that pulls objects towards each other. In other words, Gravity or gravitation is a natural phenomenon by which all things with mass or energy, including planets, stars, galaxies and even light are attracted to one another. Anything that has mass also has gravity. Objects with more mass have more gravity.
On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the tides of the oceans. Earth's gravity is what keeps you on the ground and what makes things fall.
For most applications, Gravity is well approximated by Newton's law of universal gravitation, which describes gravity as a force causing any two bodies to be attracted toward each other, with magnitude proportional to the product of their masses and inversely proportional to the square of the distance between them.
But Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as the curvature of spacetime, caused by the uneven distribution of mass.
