❗️Mass is really just bound energy, and the rest mass of an object is its intrinsic energy content.
🔬The strong force is the most powerful fundamental force in nature and is responsible for 99% of the mass in atoms.
🌌The energy of gluons, the particles that mediate the strong force, translates into the mass of protons and neutrons.
🌟Confined energy in one spot becomes the rest energy of an object, which is what mass is.
🌍The mass of the universe is nature's way of confining vast energy and creating useful particles that give rise to life.
