It is also known as the weak force.
This idea later found application in the quantum field theory of the weak force, and its unification with electromagnetism in the electroweak theory.
Beta decay is mediated by the weak force.
There's no way a weak force such as gravity can possibly hold everything onto the planet.
Rubbia and his collaborators conducted experiments there, again studying the weak force.
Gravity is the weakest of the four fundamental forces and appears to have unlimited range (unlike the strong or weak force).
During the quark epoch, the electroweak force split into the electromagnetic and weak force.
In particular one can assume that the landscape of universes contains ones where the weak force has a different strength compared to our own.
