Four Fundamental Forces of Nature!

The interactions in the Universe are governed by four forces (strong, weak, electromagnetic and gravitational).

Physicists are trying to find one theory that would describe all the forces in nature as a single law. So far they have succeeded in producing a single theory that describes the weak and electromagnetic forces (called electroweak force). The strong and gravitational forces are not yet described by this theory. 

FUNDAMENTAL FORCES:

Interaction	Relative Strength	Range	Mediating Particle
Strong	1	Short	Gluon
Electromagnetic	0.0073	Long	Photon
Weak	10-9	Very Short	W,Z
Gravitational	10-38	Long	Graviton
