The weak force is much weaker than electromagnetism at typical distances within an atomic nucleus (but is still stronger than gravity), and has a short range, so has very little effect as a ''force''. What it has instead is the property of changing one particle into another. It can cause a down quark to become an up quark, and in the process release a high-energy electron and electron anti-neutrino. This is known as {{w|beta decay}}, a form of radioactivity. Over even shorter distances, {{w|electroweak theory|and much higher temperatures}}, the weak interaction and electromagnetism are essentially the same, thus being merged to form the {{w|electroweak force}}. The electroweak force was also mentioned in a later comic, [[1956: Unification]]. | The weak force is much weaker than electromagnetism at typical distances within an atomic nucleus (but is still stronger than gravity), and has a short range, so has very little effect as a ''force''.
