NIST's sealed findings,
A decade’s worth of effort,
Gravity still strange.
A decade’s worth of effort,
Gravity still strange.
A decade-long NIST experiment has produced a new measurement of the universal gravitational constant that differs unexpectedly from another leading result, deepening a 225-year-old physics puzzle. The discrepancy is tiny, but for one of nature’s most fundamental constants, it is large enough to keep scientists…
