Why in physics, "weaklessness" might not be such a good thing for existence



Why the Weak Nuclear Force Ruins Everything” on Sci-Show. This is a little different from most posts on this blog.  It's only a hypothetical risk. 


Of the four major forces, the weak nuclear force is the only one to violate spin symmetry laws and to treat anti-matter and matter differently.

Some physicists have proposed some alternate universes might be “weakless” – which would mean no radioactivity and no decay of elements, and no nuclear weapons.

That means no North Korea’s.  But it might also mean that since matter and anti-matter would cancel out, there would be no universe at all.

So in physics, ideological equality, however correct politically, isn’t always what you want.
