The mass-energy formula E=mc2 shows that energy and mass can be transformed into each other, and the speed of light is constant. Scientists can use it to calculate the energy released by a certain amount of mass during transformation.
The most famous application of E=mc2 is not only to provide a theoretical basis for making atomic bombs, so researchers say that this calculation can be regarded as one of the most important digital calculations ever made.
Extended data:
The nucleus is composed of protons and neutrons, while protons are composed of elementary particles-quarks and gluons. Gluons transmit strong interactions, and are not components of matter, with a mass of 0.
In particle physics, it is one thing to know the existence of something, but it is quite another to understand its mechanism. Physicists have been puzzled by this problem since they discovered the existence of protons 1989 years ago.
