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 ! dry.gif

Thanks biggrin.gif

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

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)

well, there's this way...that way....that way.....or that way.....or the other way.....


what is force? a current?

what is it?
