Gravity is one of the fundamental forces of the universe and is at the forefront of every moment of our conscious experience. It keeps us glued to the ground, kicks baseballs and basketballs out of the air, and puts something in our muscles to fight. From a cosmological point of view, gravity is equally consequential.

From clouds of hydrogen falling on their stars to galaxies swirling together, gravity is one of the few players that determines the wider evolution of the universe.

In some ways, the story of gravity is also a story of physics, with some of the biggest names in the field rising to fame by defining the force that governs their lives. But even after more than 400 years of study, esoteric power remains at the center of some of the discipline's greatest mysteries.

Four fundamental forces act on us every day. The strong force and the weak force act only within the centers of the atoms. The electromagnetic force controls more charged objects (such as electrons, protons, and shaggy rug socks), and gravity drives objects with mass.

The first three forces have largely escaped human attention for centuries, but people have long speculated about gravity, which acts on everything from raindrops to cannonballs.

Ancient Greek and Indian philosophers noted that things naturally move toward Earth, but it would take a flash of Isaac Newton's insight to raise gravity from an object's occult inclination to a measurable and predictable phenomenon.

Newton's leap, published in his 1687 thesis, "Philosophie Naturalis Principia Mathematica", was the realization that all objects in the universe, from grains of sand to the most massive stars, are attracted to all other objects. This notion integrates seemingly unrelated events, from apples falling on Earth to planets orbiting the Sun. He also set the numbers for gravity: When you double the mass of an object, it attracts twice the force you decide to have, and this gives two objects close to twice their composition. Newton incorporated these ideas in his law of universal gravitation. play bazaar

Newton's description of gravity was accurate enough to determine whether Neptune existed before anyone could see it in the mid-19th century, but Newton's law is incorrect. In the 1800s, astronomers noted that the ellipsoid sensed by Mercury's orbit revolved around the Sun faster than Newton's theory predicted, suggesting that there was little difference between his law and Newton's laws. There was a discrepancy. Newton. Nature. gives. This answer was eventually resolved by Albert Einstein's theory of general relativity, published in 1915.
