All things are made up of atoms. When 42 of an atom travels at almost the speed of light, and we put more energy into it to 43 the speed, it begins to increase in mass. The energy that makes it travel fast cannot make it travel beyond the speed of light—nothing 44 light can travel that fast—so the energy goes into the thing itself and increases its mass. Energy 45 into mass.
