SUMMARY

The newly measured value for the gravitational constant G is 6.67387(0.00027)×10^–11 m^3 kg^–1 s^–2, which is 5 parts in 10^5 smaller than previously published values. This measurement was achieved by utilizing large masses made of stainless steel and copper, with results showing good agreement between the two materials. The findings further constrain variations in G related to nucleon type, enhancing the precision of gravitational measurements.

PREREQUISITES
  • Understanding of gravitational physics

They have just measured a better value for G, the granviational constant.

Announcement of New Value

"After combining all of the measurements we get a value of G = 6.673 87(0.000 27)×10^–11 m^3 kg^–1 s^–2. This new value is 5 parts in 10^5 smaller than our previous published values. "

Thanks SelfAdjoint.
from the same source: The new measurements have used both stainless steel and copper large masses. The values of G for the two sets of masses are in good agreement.
Further constraining differences in G due to nucleon type (etc). :smile:
