Using two separate tests, scientists have measured a new value for a fundamental natural quantity – G, the gravitational constant – that is slightly higher than previous experiments. Though ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers ...

This gravitational constant is used to give the value of the force between two objects with mass. It is used in the following gravitational model. In this expression, ...

"The gravitational constant is a fundamental constant of physics, so it is important to test this basic assumption using objects at different places, times, and gravitational conditions," added Zhu.

Newton’s gravitational constant — or “Big G” — determines the strength of gravity, affecting how objects like these apples fall. But Big G is hard to precisely pin down.

The gravitational constant, also known as G, provides an answer. A new method for measuring G could help scientists look for the subtle additional effects from extra dimensions.

Gravity, one of the four fundamental forces of nature, appears reassuringly constant across the Universe, according to a decades-long study of a distant pulsar.

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 ...

Because the value of the cosmological constant is very small (10 –52 m 2), it had been assumed that it would have a negligible effect on the mathematical descriptions of gravitational waves. However, ...
