引力强度测量精度创历史新高

Gravity’s strength has been measured more reliably than ever before Leah Crane FOR centuries, physicists have been trying to measure the strength of gravity, a number called “big G”. The measurements have never lined up with one another, hinting that either we don’t fully understand our experiments or perhaps we don’t fully understand gravity. The latest test doesn’t confirm either of these scenarios – but the extraordinary precision and care taken in the newest big G experiment may finally bring researchers closer to a consensus. compare theirs to ours,” says Schlamminger. “In the end, I think it will be about which era of humanity can measure this best, with the most agreement between the measurements.” …
