May 23, 2025 · In the end, gravity is not just a force that pulls objects together—it’s the story of connection, coherence, and the unity of the universe. It is the glue of the cosmos, the silent sculptor …

Gravity is the force of fundamental attraction between all things that have mass or energy. It feels powerful to us in our daily lives, but it is by far the weakest of the four known forces in nature.

Newton’s universal law of gravitation, formulated in his great work of mathematical physics, the Principia, published in 1687, was the first great work of force unification in physics.

We understand that gravity is fundamentally a purely attractive force – it can only pull, never push – and that it is generated by any object with mass. But humankind has been trying to find a better answer …

According to Newton's law of universal gravitation, gravity is a force between any two objects with mass. Three numbers affect its strength: the mass of each object, and the distance between them.
