A scene from the movie Gravity.

In real life, gravity is always bringing us down, particularly scientists who attempt to measure gravitational force.

Try as they might, physicists cannot agree on a precise value of the constant called Big G, which denotes the strength of gravity.

It's tough to measure because gravity is incredibly weak compared to other fundamental forces.

Big G is a fundamental constant of nature, and as such I think it is important to measure its value precisely.

Stefan Schlaminger of the National Institute of Standards and Technology.

The world's best experiments keep turning up different answers that are incompatible with one another

and diverge by about 40 times the uncertainty of the most precise experiment.

The discrepancy is not just embarrassing.

Knowing the true value of Big G is important in various fields,

for example, in efforts to unify general relativity with quantum mechanics in a quantum theory of gravity.

Aiming to solve the problem, Schlomenger is organizing an ideas lab,

gathering under the auspices of the National Science Foundation in July.
