Here's what you need to know about gravity:
* It's a fundamental force: Gravity is one of the four fundamental forces of nature, alongside the strong nuclear force, weak nuclear force, and electromagnetism.
* It's always attractive: Gravity only pulls objects together, never pushes them apart.
* It depends on mass and distance: The more massive an object, the stronger its gravitational pull. The closer objects are, the stronger their gravitational attraction.
* It's a long-range force: Gravity's influence extends infinitely far, though it weakens rapidly with distance.
* It's responsible for:
* The orbits of planets around stars.
* The formation of stars and galaxies.
* The weight of objects on Earth.
* The tides.
The theory of gravity was first developed by Isaac Newton, but it was later refined by Albert Einstein's theory of general relativity, which provides a more accurate description of gravity, particularly in strong gravitational fields.
