The four fundamental forces of nature are: gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force.
See lessThe weak and strong nuclear forces are very short-ranged, and we don’t directly experience them. However, they are essential to the structure of matter, and determine which nuclei are stable and which decay.
Here are some more details about these forces:
Electromagnetic force
Also known as the Lorentz force, this force acts between charged particles. Opposite charges attract, while like charges repel. The force can be felt from an infinite distance, but it’s very small at that distance.
Spontaneous symmetry breaking
This is the process by which the forces separated from each other in the early universe.
Standard Electroweak Theory
This theory unifies the weak and electromagnetic interactions. Glashow, Weinberg, and Salaam won the Nobel Prize for this in 1979.
