The gravitational constant is the key to unlocking the mass of everything in the universe, as well as the secrets of gravity.

Yes gravity is constant wherever it's found in the universe, but we don't exactly know how forceful it is.

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 ...

Big G, known formally as Newton’s gravitational constant, describes the strength of gravity. But its precise value remains a mystery. Neil Webb ...

The results of a painstaking 10-year experiment to calculate the value of “big G,” the universal gravitational constant, were published this month—and they’re incompatible with the ...

A fundamental constant that sets the size of the gravitational force between all objects has finally been pinned down using the quirky quantum behavior of tiny atoms. The new results could help ...

Perhaps the most difficult constant to measure is the gravitational constant (G). This gravitational constant is used to give the value of the force between two objects with mass.

Mutual attraction: why is it so difficult to pin down the gravitational constant? (Courtesy: iStock/FrankRamspott) Two extremely precise measurements of the gravitational constant G have yielded ...

Researchers have measured Newton’s gravitational constant, known as Big G, with the greatest precision yet.

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 ...

Researchers at ETH Zurich 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 ...
