Who calculated the mass of earth?
That's fascinating! Has anyone else ever measured the mass of the earth since then?
Yes, there have been many different methods used to determine the mass of the earth over the years. For example, in 1798, the French scientist Henry Cavendish used a torsion balance to measure the gravitational attraction between two large lead balls, and from this he was able to calculate the mass of the earth.
