According to physicist Albert Einstein's famous equation $E=mc^2$, antimatter is theoretically the most energy-dense substance in the universe. The total annihilation of just one kilogram of antimatter with one kilogram of matter would release an extraordinary $1.8 imes 10^{17}$ joules of energy, a number far beyond anything produced by nuclear fission or fusion. However, this substance is not a viable energy source for humanity due to immense production and storage challenges.
