What is the weak force?
The weak force pairs particles up and can turn one member of a pair into the other, and it grips only left-handed particles, those spinning like a left-hand screw as they travel. It is three of the twelve ways each smallest piece of the world can respond, a block that shuffles two slots. Matter therefore comes in weak pairs, the up quark with the down, the electron with its neutrino. In 1956 Chien-Shiung Wu's team chilled cobalt-60 close to absolute zero and watched it decay. The electrons flew out against the nuclear spin, where a mirror-image world would send equal numbers both ways, so the weak force tells a world from its reflection. Its carriers, the W and Z particles, are heavy because their ripples drag along the settled background read as the Higgs field.

This answer comes from OPH, Observer Patch Holography. OPH is a rigorous, consistent and complete description of the unified, self-creating computational Universe we inhabit. Its consistency is machine-checked: the fixed point at its core is constructed explicitly, and a theory with a model contains no contradiction.
To understand OPH and check every step yourself, start with the free book Reverse Engineering Reality. It builds the theory from the ground up, and the OPH Notebook answers your questions while you read.
