NIST Reports New Big G Value After Decade-Long Torsion-Balance Study

A new experiment deepens the mystery over gravitational constant, Big G

Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps our feet on the ground and holds planets in orbit.

The gravitational constant, known as Big G, still eludes scientists

A 10-year effort to measure gravity, a fundamental force in the universe, has failed to come up with a conclusive answer.

A new experiment deepens the physics mystery over "big G"

Newton's gravitational constant, G, is still known to just 3 significant figures in 2026. New measurements merely highlight our uncertainty.

Why is the gravitational constant, or big G, so mysterious

Scientists reveal findings from a ten-year experiment measuring Newton's gravitational constant, uncovering perplexing results that deepen the enigma surrounding Big G.

Scientists question gravity constant after new measurements

A major international experiment aimed at measuring Newton’s gravitational constant has produced results that conflict with previous calculations, reopening debate around one of physics’ most difficult fundamental constants. After nearly a decade of research, scientists obtained a new value for the gravitational constant “Big G” that differs from earlier measurements and from the reference values […] The post Scientists question gravity constant…
