Wheel turn round and round, well go back to Matt* and do it again. Do it again - Steely Dan (*adapted) But let me say that again, because it is so important: this relation E=mc^2 does not mean that energy is always equal to mass times c^2; only for an object that is not moving (and therefore has zero momentum) is this true. -Prof. Matt Strassler profmattstrassler/articles-and-posts/particle-physics-basics/mass-energy-matter-etc/mass-and-energy/
