The second form of energy is the electromagnetic force which works among the electric charged particles. It is more powerful than the gravitational force million times. It is represented in the repelling force among the particles of different charges and in the attracting force among the particles of like charges. This repelling and attracting forces annihilate each other. Hence, the total of the electromagnetic force in the universe is almost zero. However, as far as the particles and the matter atoms are concerned, this force remains the most powerful force in the Universe. The electromagnetic force is the force that compels the electron to whirl around the nucleus exactly like the gravitational force which compels the earth (and the other planets of the Milky Way) to whirl around the Sun. This proves the uniformity of the Universe from its smallest particle to its largest galaxy and that Allah is only One without a partner or a rival. Physicists say that the electromagnetic force is the result of the alternation of great numbers of particles which almost have no weight and called photons.

The third force is the third nuclear force which represents the glue that holds nucleons together. This force reaches its utmost in the ordinary levels of energy and it weakens with the gradual increase of these levels.

The fourth force is the weak nuclear force and it is the force responsible for the radioactivity. Whereas the strong nuclear force weakens in the high levels of energy, both the weak nuclear force and the electromagnetic force reach their utmost in these levels.

The unification of forces in the Universe:

Physicists presume that the electromagnetic, strong, and weak nuclear forces were a unified force described as the "grand unification theory." This theory is considered a step to another theory that unifies all the cosmic forces into one great force, the thing that proves that Allah is only One. From this great force, the four known cosmic forces (the gravitational force, the electromagnetic force, and both the strong and the weak nuclear forces) emerged right with Big Bang {Al-fatq} which means the phase when the earth and heavens exploded after being a one solid mass). Except for the gravitational force, all the other cosmic forces reach the same rate at very high levels of energy called "Grand unification energy). Hence, these three forms of energy are three facets of one force, the gravitational force could be part of which as it is a very long-range force that has control over the cosmic bodies and the great complexes of matter. Therefore, it could be, theoretically, neglected as a kind of simplification when dealing only with elementary particles or even with atoms of elements.

This uniformity of the Universe and the energy in it, along with the spread of pairs in creation is a clear-cut evidence that the Creator of this Universe, unlike His creatures, is only One without a partner.
