Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...
