A new study examining some of Leonardo da Vinci's sketches in the Codex Arundel reveals the artist calculated the earth's gravitational constant at a 97% accuracy rate.

They've been used to measure Newton's gravitational constant, G, test the inverse-square law, and search for new gravitational phenomena," explains Shin.

Chae says, "The gravitational anomaly is clearly imprinted in the data. One cannot remove it. It is mysterious to many scientists why gravity is boosted by about 40% when the internal acceleration ...

The Einstein equations in their original 1915 (pre–cosmological constant) form did not describe a static universe but rather one that was constantly in flux — always expanding or contracting ...

Newton’s law of gravitation defines that force F as: In this equation, m1 and m2 are the masses of two objects, r is the distance between them, and G is the universal gravitational constant.

From apples to planets, the force of gravity can be described using this equation where G is something called the gravitational constant (6.67 × 10^-11 newton-metre^2-kilogram^−2, or big G ...

The strength of this force depends on the gravitational constant. Denoted by a ‘G’, it is a fundamental physical constant. It was first accurately determined by Henry Cavendish in 1797.

There was a secret inside the envelope in the hands of Stephan Schlamminger, one of the world’s leading experts in experimental tests of gravity. He appeared to be on the verge of opening the envelope ...

Big G, known formally as Newton’s gravitational constant, describes the strength of gravity. But its precise value remains a mystery. Neil Webb By James R. Riordon July 20, 2023 at 8:00 am ...
