How big is Big G? Mystery deepens after ten-year effort to measure gravity’s strength
The Endless Pursuit of Huge G: Why the Gravitational Constant Remains Physics’ Greatest Mystery In the world of fundamental physics, some numbers are etched in stone. Others, though, remain frustratingly elusive. Big G—the gravitational constant that describes the pull between two objects—is the latter. Despite centuries of effort, it remains the least precisely known fundamental … Read more
