WebIt turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less … The mass of the observable universe is often quoted as 10 tons or 10 kg. In this context, mass refers to ordinary matter and includes the interstellar medium (ISM) and the intergalactic medium (IGM). However, it excludes dark matter and dark energy. This quoted value for the mass of ordinary matter in the universe can be estimated based on critical density. The calculations are for the observable universe only as the volume of the whole is unknown and may be infinite.

For nearly half a billion years after the birth of the universe the only elements that existed were hydrogen and helium They aren't heavy. However, after stars were born, lived, and died, the universe started getting seeded with elements heavier than hydrogen and helium that were "cooked up" inside stars.
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. In everyday life here on Earth we think of weight and mass as the same thing.
