Hi
I have a simple question if someone will be kind to answer - I know there are 4 forces (S,W,EM,G) , but why only 4 ? seems few to me !  Thanks  |

I QUESTION WHETHER RADIO ACTIVE INSTABILITY IS ACTUALLY A FORCE. IN THAT CASE THERE ARE ONLY THREE.

4? That many?
It was my understanding that W and EM have been unified, so 3. And unified with S, that would be 2. We just lack a unification with G to have only 1. |

When a baseball pitcher throws a ball and it accelerates off his hand what force is that among the 4? It is just called force because doesn't have a special name? When a bug orbits a bug light before getting zapped what force is causing this bending in space-time so he is able to orbit. And how does space-time suddenly bend even more so he hits the light? Do such bug have control over space-time?

All interaction between matter in everyday life is electromagnetic force between molecules (except for the small gravitational force, obviously) |
