What are gravitons, and do they really exist?
Web19 mrt. 2024 · To Newton’s contemporaries, gravity was a terrestrial force; it was restricted to objects near the Earth’s surface. What Newton discovered in the family apple orchard was that gravity is a universal force. It extends all the way out to the planets, to the Moon, to the stars, and farther. 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, and causing masses to move along geodesic lines. Meer weergeven In physics, gravity (from Latin gravitas 'weight' ) is a fundamental interaction which causes mutual attraction between all things with mass or energy .

And Newton, who has just discovered gravity, decides to challenge his friend. With a sly smile he asks Lagrange to explain why the apple fell to the ground. Newton waits in suspense to see whether Lagrange is clever enough to figure it out. After some time, Lagrange exclaims, “aha!”. cioffi law pa
