Scientists continue to struggle with precisely measuring the gravitational constant 'Big G', one of physics' fundamental constants. Recent experiments have failed to produce a more accurate value despite advanced measurement techniques. The ongoing challenge highlights fundamental measurement limitations in physics.
Background
The gravitational constant G is one of the fundamental constants of physics that determines the strength of gravitational attraction between objects. Despite being first measured over 200 years ago, it remains the least precisely known fundamental constant.
