How much mass does the universe have
After months of measurements, Cavendish was able to determine the gravitational forces acting within his torsion balance — and, by comparison to Earth’s gravity, he was then able to calculate how much the Earth must weigh, and, from Earth’s known size, the average density that must correspond to that weight. The … See more Long before Mason and Dixon set to work, Sir Isaac Newton had demonstrated that gravity is a universal force, acting in the same way on both everyday objects and … See more Pause here for an important distinction.
