Gravity is the universal force of attraction acting between all matter. Learn about its history, theory, measurement, and effects on Earth and the cosmos from Britannica.
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction which causes mutual attraction between all things that have mass. Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 ...
30 de jul. de 2023 · To summarize, according to Einstein, gravity is the curving of spacetime by all the objects in it, combined with the "geodesic" (straight) motions of those objects through the spacetime.
Gravity is the force that attracts massive objects and determines how they move. Learn how Newton and Einstein described gravity, and why it is mysterious and fundamental.
ESA / Science & Exploration / Space Science. We understand that gravity is 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 answer this question for thousands of years.
