 * Strength of 4 Forces of Nature **

The four forces of nature are electromagnetism, gravity, the strong nuclear force and the weak nuclear force. Gravity is perceived as strong, however, by jumping from a building, I do not crash through the ground because I, or rather my body is levitating above the ground due to repulsion between electrons of atoms, a consequence of the electromagnetic force. Considering how a small piece of sidewalk can overcome the gravitational attraction between me and the earth, gravity is a very weak force. In fact, it is thousands of times weaker than the electromagnetic force and is even weaker than the weak nuclear force.

The weak nuclear force is released when atomic bombs are detonated. (This is the force detected by radiation detection meters) The strong nuclear force is what holds nuclei together and is the strongest of all forces.
