Two vertical parallel number lines, scaled logarithmically. The left one refers to energies, listing the amount of energy of 1 cubic meter of empty space, or the energy gained by a grain of sand falling one meter. The right hand side shows masses, such as the mass of a proton, the mass of dark matter in a cubic meter of space, the mass of a water molecule, or the mass of a Higgs boson. The examples listed span a scale of a couple orders of magnitude, so, they're very loosely similar.
You may have heard of E=mc2.
You may have even heard of it written more properly with a squared symbol.
But... how do mass and energy *actually* compare? Spend your Friday exploring the scales of the universe in this Minute Labs project: Mass-Energy Scale. 🧪 ⚛️
