Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps ...

It does not resolve the discrepancy, but it gives physicists one more data point in their ongoing quest to nail down a more precise value for Big G. Isaac Newton introduced the concept of a ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest numbers to nail down.

The gravitational constant, dubbed big G, determines the strength of the attraction between two masses anywhere in the universe. Scientists have been trying to measure big G for over 225 years, but ...
