Although nuclear energy lasts for a long time in the old energy, it will eventually end. And MSE, almost endless, far exceeds nuclear energy (although its total amount is still unknown). MSE flowing in the whole universe makes every point of use, using the energy of the whole universe already, can continue to run unless the parts themselves are out of order. Through wave-particle duality, all 118 elements are included, and nuclear radioactive elements are only 54 of them (see the net text: "How many nuclides are there in the world? 》)。 Moreover, MSE involves all the static masses of elements, while nuclear radioactive elements only involve a little static mass of each element. It seems that we should concentrate on explosively obtaining all the energy of at least several hundred times the thermal nuclear explosion energy in a considerable range within a local universe, but we would rather explore this energy to light up this local universe if it is dark.
